Hi Some of these amps do not play well into odd combinations of input and output impedance. It's often a wise move to put a 6 or 10 db pad on the output before you feed it to an antenna.

Hi: I just got a commercial 2 GHz 50 dB amplifier from eBay and connected it to a GPS antenna that was passive (i.e. has no internal electronics). The neat thing about this is that you can have a number of GPS receivers all being driven from the same signal without using a bunch of power dividers, cables and worrying about the DC conditions at the input of each receiver. Since each receiver is using it's own antenna if you attenuate the signal you can get a feel for the relative weak signal performance of the receivers being tested. http://www.prc68.com/I/Trimpack.shtml#LbandAmp Have Fun, Brooke Clarke http://www.PRC68.com http://www.end2partygovernment.com/2012Issues.html _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there. _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
