Splitting GPS
Splitting GPS
(OP)
Here's the scenario:
I want to insert a splitter in the cable coming from the GPS antenna and connect it to multiple GPS receivers I obviously get a loss here, but compensate for this loss, would an LNA suffice without injecting too much noise? If the LNA compensated for the loss, let's say 10 dB, roughly how much of a hit in C/I would I see (in dB).
thanks,

RE: Splitting GPS
If you split 3 ways your loss becomes -5dB, four ways -6 dB and 5 ways -7dB. Those numbers are at each reciever plus your insertion loss.
Hope this helps.

btw, C/I = Carrier to Interference ratio
thanks for the info
