I want to run about 4 separate GPS units of disparate manufacture from a single antenna. My plan is to provide power for the antenna via a bias tee (power inserter) at the bottom end of the antenna's cable, then use an isolating splitter on the receiver side of the bias tee to split to the various receivers.
My question is: how much isolation between receivers is likely to be necessary? Real life splitters are only so-so in isolation performance (15-25 dB), and may e significantly worse if the antenna's LNA's output is a poor match. So I'm wondering if I'm going to need more amplifiers in the splitter's outputs just for the sake of adequate isolation between the GPS receivers. Thanks, Dana K8YUM _______________________________________________ time-nuts mailing list -- time-nuts@lists.febo.com To unsubscribe, go to http://lists.febo.com/mailman/listinfo/time-nuts_lists.febo.com and follow the instructions there.
