Listed on eBay as a L1/L2 antenna with decent specs. They seem to indicate it is as good as a choke ring antenna. I suspect it is just a patch in a fancy package. That is what the Leica and Trimble survey grade antennas I have contain anyway. I bought one but haven't had the chance to do any testing. I couldn't figure out how to get to the insides to take a peek without damaging it. My antenna testing abilities are pretty feeble. Mostly, I will just compare it to the Leica and Trimble to see how many satellites it sees and look at position wander of the uBlox. Is there any simple way to judge the quality of a GPS antenna? _______________________________________________ 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.
