Does anyone know what the impedance is on our sat. ant. cable 75ohm or 50ohm??

thx.

 

50 ohms nominal impedance
2320.0-2345.0 MHz Rx Frequency

 

You are definitely not a nimrod when you have answers to questions like this thread.

Thank you very much.

 

One more Q.

Can our OEM Sirius sat radio antenna support a GPS?

If yes, would I just have to get a T-adaptor connector and run a 2 cables from there (1 to the GPS and 1 to Sirius radio)?

 

"Can our OEM Sirius sat radio antenna support a GPS?"
Probably not, unless it is specifically designed for both services. Satellite Radio sits at 2320.0-2345.0 MHz, and GPS is at 1575.42 MHz, in the RF spectrum. The antennas for these services are amplified to permit sucessful reception here on earth of the extremely weak signals (usually below the ambient electronic noise levels, in fact) from the satellites; hence, they use sharply-tuned amplifiers, and unless the antenna amplifier is designed for both bands, satisfactory dual-service operation is not likely.

 

nimrod is correct. they will not support GPS ..

 

Well the good thing is that based on this information I now have one less mod to do.

Thank you guys.
