1  VSAT technology and installation / Satellite dish installations - pictures and descriptions / Re: SatLink meter questions--Bell sats
 on: Yesterday at 11:03am 
   
Regarding the Satlink WS-6906 satellite meter, there is a copy of the manual on the internet at https://ftp.dipol.com.pl/TV,TV-SAT/Miernik%20WS6906/6906manual.pdf

The Satlink web site at http://www.sat-link.co.uk/store/SatLink-WS6906-DVB-S-Satellite-Finder-Meter-WS69... has an option to download (at cost) a software update.
If you want this I suggest you check first by phone or email that the new software has up to date data for Nimiq 4 and Nimiq 6

What to do:
You can try adding a new satellite yourself. Examine the data for Nimiq 4 to get an idea of what needs to be input.

If you use the meter as a simple power meter, at maximum sensitivity, you can swing the dish sideways across the top of the orbit arc and you will see multiple tiny blips as you pass each satellite. You can peak up on any of these and repeat the sweep.

At a powerful satellite you can use your set top box or the meter to try and identify. Getting Nimiq 4 would be a good start.

Once you know what satellite you can then step along to your wanted satellite.

Satellites near your longitude and the carrier frequencies, polarisations and symbol rates are listed here: https://www.lyngsat.com/america.html

2  VSAT technology and installation / Satellite dish installations - pictures and descriptions / SatLink meter questions--Bell sats
 on: Apr 16th, 2024 at 2:49pm 
   
Hello out there ! Wonder if someone can help.
I just bought a SatLink meter model WS-6906; it can't be that old; it's for sale on Amazon.
Googling support for this meter seems non-existent. (?)
Anyway--I'm using the meter to locate Bell sats Nimq 4 & 6.(82 & 91)
Going thru the meter menu; I found Nimq 4 but Nimq 6 wasn't there.
From my understanding; it's Nimq-6 that's critical.
Has anyone out there used this meter to find this info ?
Also---anyone know how to check / find the firmware update for this meter ?
Wondering if that might be needed so the meter will show Nimq-6
Thx in advance

3  VSAT technology and installation / Hub and VSAT satellite equipment for sale and wanted / Newly 4.5 Meter C & Ku Dual-Band Satellite Antenna
 on: Apr 10th, 2024 at 3:19am 
   
Along with broadcasting and Internet access, satellite communications have transformed the way of global connectivity, enabling seamless communication over long distances. As one of the basic components of the satellite communication system, the satellite antenna is responsible for transmitting and receiving signals to satellites in space.

Previously, we had shipped one set of 7.3M C/KU Dual bands receive only antenna to Europe and the antenna operates well with local network until now. In this article, we will explore the excellent performance and advantages of the newly updated 4.5m C & Ku Dual Band Satellite Antenna.

1. What is satelliteantennas?

Before going into the details of the 4.5m C & Ku dual band satellite antenna, first let us briefly discuss the basics of a satellite antenna. Satellite dishes are parabolic reflectors used to focus and direct electromagnetic signals toward or from specific points in space. The size of an antenna is a key factor affecting its performance, with larger antennas generally providing higher gain and better signal quality.

It has to be said that C&Ku dual-frequency technology is a major improvement in satellite communications. General satellite dishes usually work in a single frequency band, but with dual-band technology, one antenna can now cover both C and Ku bands. The C-band operates in 3.4 to 4.2 GHz, while the Ku-band operates in 10.95 to 12.75 GHz. This dual-band capability ensures flexibility and adaptability to changing communication needs, making these antennas more versatile and cost-effective. Below is the technical specification and diagram of 4.5m C & Ku dual band satellite antenna for reference.

Here is some extra advice about Bell satellite dish pointing.

General guide:

Set the dish elevation carefully and then boldly swing the dish sideways to find the wanted satellite. Peak up on both az and el.

Details:

Set the pole accurately vertical and set the elevation angle on the scale.  If the clamp is initially slightly slack the LNBF will sag a bit and adding 2 deg to the elevation angle will help.  This 2 deg should disappear when all is peaked up and tight.

Note the direction line on your house image and acrossthe garden. You can judge the approx sideways direction considering garden fence corners, adjacent buildings etc.

As you boldly swing the dish sideways around the az direction be alert to even the slightest signal, which may then be peaked up. When you look due south you are looking at the top of the curved orbit line. For you, at 78 west deg site longitude, 82 west is just west of due south and thus near the top of the geostationary orbit where there are several more satllites, either way, in an approx horizontal line. Futher to the west the satellites will be lower down.

You may well find the wrong satellite, in which case move along till you get to the wanted one.

If you seem to get nothing at all, check the coax cable connections. Turn the power off and verify good center pin and good braid connections both ends. Remove any braid fragments that may be short circuiting the power supply.

Familarise yourself with the Bell set top box instruction manual, particularly anything about initial acquisition of the satellites and dish pointing.

...

You mention aiming for two different satellites.

Some antennas have a dual or triple LNBF and in such cases the composite LNBF will need the be tilted slightly clockwise (polar angle), while you are facing forwards towards the satellite in the sky. The lower feed will correspond to the higher elevation (82 deg) satellite. Set the elevation scale to the average value. The small amount of clockwise rotation will correspond to the slope of the red line between 82 and 91.  The distance between the two feeds may well be preset to suit sites across Canada and satellites 9 deg apart. Triple feeds are possible for 82, 86.5 and 91 satellites with 4.5 deg spacing.

Thx Eric ! Yes---I've tried that already---was hoping someone had already done this & could confirm those angles. Hopefully someone else will respond  Smiley

This page should help you:
https://www.satsig.net/maps/satellite-tv-dish-pointing-canada.htm
Move the map around till your location is in the middle.

You should see something like this below:

...

Switch to Satellite View to see your house and proposed antenna location on wall / roof etc.
Select satellite at 82 west or 91 west and write down the angles.
You need to move the map slightly to get the calculations redone.

Hello--new member here !
Hoping someone can verify something re: Bell satellites Nimiq-4 (82) & Nimiq 6 (91) Could someone advise on the correct elevation & skew angles for the sat dish. I am located in Trent Lakes, Ontario, Canada; just north & a little east of Peterborough, Ontario, Canada. Thx a lot in advance---great website !  Smiley
