I have 3 AT504 Antenna's.. They look good just as artwork on the wall. Two are GG and one is gps only. I am still using one for a base station but was wondering what happened to all the other 504's out there - I would buy them for scrap value with ideas to make a sculpture.
Does anyone have ideas how to upgrade the guts for these antennas to listen to all the new signals or if it is technically possible?
Nothing wrong with an AT504, especially the GG version, lots still in use in networks around the country, I don't think they are being dumped on the scrap heap quite yet.
I don't know about upgrade on those, haven't heard of one, I know there was upgrades of the equivalent Trimble GPS model to make them into "GG" models.
