Know the OP asked about antennae and you are discussing receivers, but I??ve definitely experienced a geofenced data collector. ?ÿBought a used tablet allegedly with SurvPC TS/GPS from overseas. ?ÿIt worked great with my gun, no point limits. ?ÿIt worked well with my GPS receiver??until I saved a point.
Got a ??out of authorized region? error and it deactivated the license. ?ÿI liked SurvPC so much I bought a copy from my local dealer, wiped the tablet, installed a clean upgraded version of Windows, and installed my SurvPC. ?ÿThe tablet was in great shape so I made out ok $-wise on the deal, though I lost a bunch of time figuring it all out. I probably wouldn??t have gone to the tablet & SurvPC if I hadn??t tried it all out on the cheap, so Carlson racked up a full price sale due to a very dodgy ebay listing. ?ÿ
