What is the model number of your LNB ? Do you have a large, grey coloured, wedge shaped plastic box behind the antenna ? Best regards, Eric |

![]() This image above shows Hughes Universal LNB PN LNB 1501882-0002. The receive polarisation is Horizontal name. No adjustment amount has yet been applied. Please say if you have a large, grey coloured, wedge shaped, plastic box behind the antenna, similar to that shown on the left of the image below ?. ![]() This image shows the elevation angle being set using an inclinometer. Read how to make inclinometer Please look for a tapered grey adaptor tube between the conical feed horn and the LNB module. ![]() Does such a grey spacer tube exist ? The tapered grey adaptor tube has flanges at each end. The smaller flange, with 12 holes, has 2 tick marks on one place and 1 tick mark in another place. The single tick mark must be directly away from the feed support arm tube. On the throat of the conical horn is a 505 mark. This 505 mark should also be directly away from the feed support tube. The fat lump underneath must be towards the feed support arm. Best regards, Eric. |

to day i have tried alot the high signall i got a bout 29 ans stuck there \ my lnb detail HS 10.95-12.75GHz p/n 1501882-0002 REV.A S/N J09C025114C1 it is commitsstion pic that i have applied |

The signal scale works in two ranges: 0 to 29 refers to signal power. You will get readings on all satellites as you pass them. Really powerful satellites will give a reading of 29, which is the maximum value. The second range goes from 30 to 100. Expect a result in the 90's. This scale only appears once your receiver has detected the wanted carrier. This means you have the correct satellite, correct polarisation, symbol rate, frequency, LNB type, tone on/off, in the config screen are all correct. Pointing: Using https://www.satsig.net/maps/satellite-dish-pointing-afghanistan.htm I get quite different elevation angle. I don't know why the figures differ. Find and check your location on the map and check. What town are you in ? Polarisation: As per your picture with the feed arm at the bottom of the dish and the Universal LNB cable sticking out at the side. This is Horizontal polarisation name starting position. You want Vertical name receive polarisation. If you have a large grey wedge shaped plastic box behind the dish go there and loosen the 4 polarisation bolts and turn the dish anticlockwise by 90 deg (as viewed from behind the dish). You are now at vertical polarisation name starting position. Now adjust the dish by an amount of 47 deg clockwise. Use the scale to count the along the amount of 47. Ignore the numbers if they go backwards from 90, for example. Having the wrong polarisation will result in high signal power (a mixture from both polarisations) but the two signals, from each polarisation, will cause severe interference with each other so there is no hope of receiving anything. With the polarisation adjusted correctly (+/-1 deg accuracy) the unwanted interfering cross-pol signal will be nulled out and disappear. Best regards and Happy Christmas, Eric. |

![]() This shows the LNB BUC assembly turned in its yoke - which is not really a good idea as the 505 on the feed throat and single tick mark on the flange are no longer directly away from the feed support arm and the fat lump is no longer towards the feed support arm. The polarisation orientation is completely wrong. You need Vertical polarisation name, adjusted by +47.7 deg clockwise, as viewed, looking forwards from behind the dish. ![]() This shows the grey wedge shaped box. the elevation angle is set to about 45 deg. I think the elevation should be 26 deg. You think the elevation should be 31.6 deg. Set the elevation correct using an inclinometer. Read how to make inclinometer Are there 4 bolts and a giant circular polarisation scale on the left face of the grey wedge shaped box ? If yes then follow instructions at A below. If no then follow instructions at B below. The use of a satmeter is similar to the 0 - 29 scale on the screen readout. The satmeter will indicate at all satellites and to peak up on any. If you set the elevation correct, then swing boldly sideways, you may well find the wanted satellite on the first swing. Even if you get the wrong one, the wanted satellite will certainly be the next one either way along the diagonal sloping orbit line. Polarisation method A. You have a giant polarisation scale and 4 bolts on the rear of the grey wedge shaped box. It is possible to loosen the four bolts and rotate the entire dish through 360 deg. With the feed arm at the bottom of the dish and the Universal LNB cable sticking out at the side. This is Horizontal polarisation name starting position. You want Vertical name. You have large grey wedge shaped plastic box behind the dish; go there and loosen the 4 polarisation bolts and turn the dish anticlockwise by 90 deg (as viewed from behind the dish). You are now at vertical polarisation name starting position. Now adjust the dish by an amount of 47.7 deg clockwise. Use the scale to count the along the amount of 47.7 Ignore the numbers if they go backwards from 90, for example. The feed support arm will now be on the lower right hand side as viewed from behind the dish, facing forwards towards the satellite in the sky. Method A is best and in the unlikely event that you have been told the wrong name of your downlink polarisation it is very easy to turn the whole dish 90 deg. Note that the beam should stay pointed at the satellite even when you turn the dish. In practice you need to retighten the 4 screws and peak up again. Polarisation method B. The polarisation scale and 4 bolts on the rear of the grey wedge shaped box are missing. You cannot rotate the dish. The feed support arm is always at the bottom of the dish, near to the ground. Turn the LNB/BUC assembly in its yoke till the Universal LNB cable points upwards. This is a vertical polarisation start position. Now turn LNB/BUC assembly in its yoke by an amount of 47 deg clockwise, as viewed from behind the dish, facing forwards towards the satellite in the sky. Your system will probably now work, although the polarisation isolation will be poor. Undo the 6 screws at the 12 hole flange and reattach with the 505 and single tick mark as near as possible to directly away from the feed support arm and ther fat lump towards the feed support arm. Best regards, Eric. |

sorry my english is not good i took this info from the site that you gives the link it is my exact location and if possible show in a picture how i should polarize my lnb and other Satellite antenna dish aiming angle / pointing calculator for Afghanistan, with map Lat = 33 degrees, 8 minutes North Long = 67 degrees, 26 minutes East If you want to point a satellite TV dish at the Satellite at = 21.5 East orbit longitude Beam elevation= 28.0, Azimuth= 239.1 (magnetic compass), Polarisation= 47.7 |

Tell your service provider hub your correct location and modify the location on the config screen. Having wrong location will not affect your ability to receive from the satellite but it will prevent your transmit side from transmitting at the correct time so as not to interfere with other site uplink bursts. Best regards, Eric. |

one thing that now i notice that my Manual Commissioning page is difrent with the Manual Commissioning page wich i saw in this site this is my Manual Commissioning page pic and this is the picture i found from this froum https://www.satsig.net/bentley-walker/hx/hx50-system-manual-commissioning.gif some veules are not present in my commissioning page |
|
Dec 26th, 2011 at 2:22pm
Have they sent you a pdf page with all the information ? You should have been told: Your receive polarisation name. Your receive frequency. Your receive symbol rate. 22 kHz tone on/off. plus much more such as IP addresses etc. The information you use needs to be specific to your site now. Data related to another site, some time ago, on a different satellite etc is of no use. Best regards, Eric. |

in one prp.rtf file now the file incloud information that i dont know where to enter for example 1.Frequency Band / now in my commessiton page this 1 point there is not any place to enter this 1 point |

friends plz see this pic and tell me that i selected correct vertical recive for my lnb or no |

![]() Please send me eric@satsig.net a copy of your prp.rtf file so I can see what you have been told. I can also talk to Bentley Walker (not far from here) and clarify any problems. ![]() This shows the LNB BUC assembly turned in its yoke - which is not really a good idea as the 505 on the feed throat and single tick mark on the flange are no longer directly away from the feed support arm and the fat lump is no longer towards the feed support arm. The polarisation orientation is completely wrong. You need Vertical polarisation name, adjusted by +47.7 deg clockwise, as viewed, looking forwards from behind the dish. One option, which will get you working quickly but with poor cross-pol accuracy is as follow: Turn the feed system in its yoke till the Universal LNB cable points straight up. This is now Vertical polarisation starting position. Now apply the adjustment amount. Turn the feed system +47.5 deg clockwise, as viewed facing forwards towards the satellite in the sky. This is approx 90 deg clockwise from its present position in the picture above. The correct option, which gives perfect cross-pol accuracy involves turning the LNB so that the cable points sideways. The 505 on the feed throat and single tick mark on the flange are now directly away from the feed support arm and the fat lump is towards the feed support arm. Then turn the entire dish 90 deg anticlockwise, loosening slightly the 4 bolts at the rear and noting the 360 deg polarisation scale. The feed support arm is now on the right hand side, as viewed from behind the dish. Then adjust the whole dish by an amount of 47.5 deg clockwise. The feed support arm will now be on the lower right as viewed from behind the dish. |

Entering of this information into the config screen sets the displayed information only. Your antenna equipment does not have a remote control polarisation change capability. You cannot change the polarisation using the screen. The proper way to change polarisation is by manually turning the entire antenna 90 deg to change from Horizontal name start position (feed arm at bottom, LNB cable sideways) to Vertical name start position (feed support arm at the side and cable up/down). You can then apply the adjustment : an amount of +47.5 deg clockwise rotation of the entire antenna, while behind the dish and facing forwards towards the satellite in the sky. Count the amount along the scale - ignore the numbers if they go backwards. You can also change polarisation by rotating the LNB/BUC in its yokes but your antenna design (using asymmetric mode matched feed horn) is not designed for this to be done and it will cause bad cross-pol quality if the 505 and single tick mark are not directly away from the feed support arm. Please send your PRP.rtf file to me at eric@satsig.net so I can see what you have been told and talk about your site with Bentley Walker, if necessary. Best regards, Eric. |

Dec 27th, 2011 at 1:57pm
you need ; tv and satelite recevier . connect recevier to lnb , set this parameter your recevier . https://www.lyngsat.com/ew6.html tv channel name :Baghdad TV Channel frq:10972 pol:V sembol rate:2170 search this tv channel in your satelite recevier. if find him then are you find right satelite. |

Dec 28th, 2011 at 5:10am
And wich frequancy should i use to find the satalite thanx from all member and mr eric |
|
Dec 28th, 2011 at 9:37am
With sample reciver i can find hotbird 13degree and w7 just i cant find w6 21.5 it is realy strange i think the dish is small what u friends think |
|
Dec 28th, 2011 at 1:28pm
i fixed the dish on w7 with simple setalite then i upload the sbc file and changed the frequncy and sps the high signall i got was 29 i think some think is wrong with my medom what u friends think the dish was allready pointed on w7 |
|
Dec 28th, 2011 at 4:17pm
and instad of mr eric question all info is ok sbc file is new frequncy is new just i dont know a bout this 22khz tone on of what is this for if can give me more information thanx |
|
Dec 28th, 2011 at 6:20pm
In case what you are told about 22 kHz tone is wrong, try with the 22kHz tone off and on. This changes the LNB local oscillator frequency. One way should work. The other way will not work. Polarisation: The adjustment angle for W7 (36E) is an amount of 38.6 deg clockwise. The adjustment angle for W6 (21.5E) is an amount of 47.7 clockwise. These adjustments are applied after starting at either Vertical or Horizontal start positions, and viewed from behind the dish facing forwards towards the astellite in the sky. In case the polarisation is wrong name, try altering the polarisation quickly. Just turn the LNB/ORU in its yoke 90 deg or all the way round. There will be two good positions, opposite to each other. This only take a minute to complete the test. The modem RX LED will light up whenever the polarisation is about right. Centre the range. The tuning and symbol rate etc all should come from the rtf files you have been sent for each satellite. After inputting the sbc.cfg file, does a "Universal" option appear in the LNB pull down menu ? Power cycle your modem and look at the config screen. The data displayed should still match what is on your sheet of paper (rtf printed out). If the "Save" function does not work and the old values are stuck, please say. Is your modem an old one that has previously been used elsewhere ? Best regard, Eric. |

Dec 29th, 2011 at 1:52am
yes this device is second hand and used in one cafe net and pointed on w6 in other place and when i upload sbc file the lnb type automaticaly gos to universal and one thing my support sayed u must do telnet first what is telnet and it is neccessery to eich time and finall i think i fill the dish is and cant point to w6 mr eric i have sent u email see ur inbox my prp file see wich velue should use for 22khz on or off????? thanx you |

Dec 29th, 2011 at 9:39am
You might also include both cfg files. Thanks. Regarding you being told to use telnet. I would rather not tell you how to do this without seeing your email (please forward). If I tell you wrong it could stop your modem from working. You should only use telnet if told to do so by your service provider and then follow their instructions only. The rtf file for W6 21.5E says 22 kHz tone should be ON. Meanwhile make sure you can reliably find both the 21.5E and 36E satellites, noting for each the exact elevation and azimuth angles after peaking up (measure the lengths of the screws). I expect you will get a power reading of 29 on both satellites. Best regards, Eric. |

Dec 29th, 2011 at 12:49pm
and the new problem i face to day is when i am uploading SBC file then menul cammission and cliking on pointing the satelite to see the signall strangh sudanly all leds becom on for 1 second and after some second the system led become on and this massge came see the picture now i cant point to satailte becoz this problem stoped my work i restar the hx medom and my lap top but the same what is wrong now????? |

Dec 29th, 2011 at 1:47pm
I can't see your image. |
|
Dec 29th, 2011 at 2:09pm
this is the picture link when i power on the medom the only power is on when i connect the LAN cable the LAN led becom on and it is blinking when i enter https://192.168.0.1 |
|
Dec 29th, 2011 at 3:43pm
I note that you were told by WAFA (in their email of 19th Dec) to reset your modem to factory settings using rf command. You should only do this command if told to do so by your service provider and if your modem is not accepting (saving) new config data or not working properly. Once you have done this you will need to re-enter all the parameters from your rtf page. To do the rf command follow these PC instructions: Start, All Programs, Accessories, Command Prompt. You should see a black window. Enter telnet 192.168.0.1 1953 You should see a new line, then enter rf Best regards, Eric. |
|
Dec 29th, 2011 at 5:03pm
mr eric u r realy mastermind i did the telnet wrongly i did like this when open the CMD i wrote this telnet 192.168.0.1 1953rf this was my fault if it can makes this problem that i cant recive the signal i am sure this was my problem but the other i dont know why in my manual commission page this value dont exist or it is not important Frequency Band / KU / QPSK |
|
Dec 29th, 2011 at 6:41pm
If you did that mistake there was probably an error and there was no effect. The modem was not reset. Frequency Band / KU / QPSK Don't worry if there is no place to input this data. Best regards, Eric. |
|
Dec 29th, 2011 at 8:37pm
if u have windows xp click-star click-run scribe - cmd and press enter if is opened dark window , use this command "telnet 192.168.0.1 1953" press 3 time enter , scribe "cim" or "dim" i dont remeber try it , press enter and see menu. use "rf" command modem will reeboot. and modem turn back to factory seting. |
|
Dec 30th, 2011 at 2:21am
i think he use windows7 , telnet service is not installed as defautlt setting. if u have windows xp click-star click-run scribe - cmd and press enter if is opened dark window , use this command "telnet 192.168.0.1 1953" press 3 time enter , scribe "cim" or "dim" i dont remeber try it , press enter and see menu. use "rf" command modem will reeboot. and modem turn back to factory seting. hello thanx from ur help can u tell me can i use hx50 frquncy ans sps in sample dish to find satelite or i should find frequncy of tv |
