I kind of have to believe the specs. The two survey grade antennas I already have, a Leica and a Trimble, both have regulators in the preamp sections. The Leica has an 8 volt one and the Trimble has a 5 volt one. I intend to hook it up to a variable supply and watch the current as I increase voltage. If it has a regulator, the current should stabilize at an input voltage just above what the internal preamp operates at. If not, it should continue to rise. I am tempted to pry it apart, even if it risks damage just so I can see for myself what they are using for the preamp stages. _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there. _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
