Title: Starband with Direcway sp antenna Post by navopache on Sep 21st, 2009 at 1:18am
I am currently using a starband system and I have found a very clean Direcway SP Dish, LNB, and transmitter. My questions are:
1. Can I attach this assembly to my Starband Modem? 2. Will I see and improvements? My current dish is a .74 and the new dish looks like a .98 with a larger feed horn and transmitter. David |

I moved your post, since technically it's a Starband question. First impression is that it should work, depending upon whether or not you can configure tje newly purchased ODU for the required Tx/Rx polarization scheme. Some of the Hughes 98cm ODUs are configured for Enterprise grade service, and may not be compatible with consumer grade Starband polarization schemes.
Let me start by asking - what does the "SP" stands for? and is there a fluorescent green sticker anywhere on the TRIA (usually on either the TX waveguide or the OMT/filter) ? //greg// |

I do not know what the sp stands for. There is an orange sticked on the LNB it says Direcway LNB RSS 10.95 - 12.75. On the transmitter there is a stcker that says 1 watt radio.

Ok, a picture is worth a thousand words. But here I have to work with numbers. It sounds like you have a consumer-grade Hughes rig there, but perhaps you'd be so kind as to post the part number from the TRIA (if it's readable). Something like;
Pure ISIS 1 Watt #1032009-0003, -0004, 0005 or OSIRIS 1 Watt #1035007-0001, 0002 //greg// |

There is a number its 1032009004

Very hard to read almost gone but the number is 1032009-0004

That works partially in your favor, as the ISIS responds to voltage shifts from a compatible modem (13v=Vertical/18v=Horizontal) to change receive polarization. But from what I've read about the Gilat (Starband) modems, they put 24v on the cable. If that's accurate, it means - short of making physical modifications to the feed - you'll be limited to working H/H polarization only. That's something you'll have to work out with Starband.

Is there something I can buy to do this or will I have to build it?

Starband tells me they have no H/H assignment

Then you might want to find another buyer for that very clean Direcway SP dish, LNB, and transmitter. //greg// |
