Thuraya antenna

What's the rough cost?

A search on 42T1516P-XT-2 turns up this.

Yours seems to be on page 41 of the PDF. This is Antcom. It's funny how the same stuff goes round and round...

Antcom is the firm from which I bought mine for my roof mounted experiment.

Whether the 42T works better than the one they supplied me with back then (2009) is hard to say. They apparently could not test them because they are in the USA and Thuraya doesn't cover the USA. Under much pressure they eventually admitted this.

So I would ask them if it's any better than the one I used. But at $300 or so, that's an OK price even if it is the same one, especially if you get a piece of paper with it.

But you can test an antenna in a lab, you don't need satellite coverage. A signal generator, a power meter and a network analyzer (for the matching) does it nicely.

What kind of 8130 do they supply? 8130-3 dual release?

Antcom may or may not be EASA approved.

On an 8130-3 it will show any EASA approval in Box 13.

However an FAA 8130-3 is good for an EASA reg plane if the part is new.

Certain avionics shops also want the 8130-3 to come from the original manufacturer.

What is the time frame of your project?

Given that the Thuraya mobile transmit band is only about 50MHz away from GPS L1, do you expect any interference / desensitation of the GPS receivers? How far will the antenna be away from the GPS antenna on your aircraft?

50Mhz is no problem as there are no harmonics.

I'm not worried about harmonics, more about VCO/Transmitter noise
