Has anyone installed a skyedge pro with a seatel? If so how?

I have a customer that is requesting to use Gilat with a sky edge pro with a seatel antenna. I can not find anything on how to install it.

Gilat have been working with Seatel for a while now and have installed few SE Pro modems with Seatel Shipboard antennas.

Not sure what exactly the support you require but feel free to contact Gilat through its support website- https://extranet.gilat.com/Extranet/login.aspx?ReturnUrl=%2fextranet%2fHome.aspx

Another option is to send a direct e-mail to Yaniv at yanivm@gilat.com

No Luck I emailed him with no reply. So if any can help I am still in need of help. The type of help I am looking for is How to install the Sky edge pro with the seatel antenna. I can get the Antenna to lock on the satellit but the modem does not get a receive lock.

Check that the antenna has locked to the correct satellite by observing the receive spectrum. Beacon/tracking receivers may lock to beacons on wrong satellites if the beacon frequencies are similar.

Check that the signal to the modem is the correct polarisation.

Check that the wanted carrier L band frequency is as expected (i.e. the correct LNB local oscillator frequency is in use).

That the modem is pre-tuned to the wanted carrier.

If you are using the Gilat modem as the tracking receiver I would check that it works well with a fixed antenna on land first. Then, the modem will need to output an analogue "noise power/signal level, e.g. agc + Eb/No" and logical signal "correct carrier found". These will need to be fed to the Seatel antenna tracking controller. The Seatel tracking controller may need to be told the scaling facor for the signal level dB/volt, and the logic polarity of the "correct carrier found" lock wire. I can't remember the details. Proper common grounding of the antenna, SeaTel electronics, modem chassis and ship metal is important. The Seatel tracking controller will need to know the orbit position of the wanted satellite, the polarisation of the wanted signal and also the ship's GPS position.

Continue trying to get help from Gilat and SeaTel, otherwise it will take a long time to learn all this from scratch.

Best regards, Eric.

Thanks Eric I have already checked with Gilat and they told me if I did not buy it from them then they will not help. As for as seatel they stated that they never saw this config before. I have used Gilat modems with fixed dishes before and also seatel with iDerct modems before. But Never the gilat with the seatel. I know it can be done Becuase I know of a company (competitor) is doing it. Thanks for the help.
