[time-nuts] Re: Help needed IDing GPS antenna
Hi John, Since TOPCON is a manufacturer of topographic instruments, I think that this antenna is used for this kind of work. GPS antennas made for geodesy or surveying usually have a very good quality and their prices are according to it. But given the label at the bottom it could be used by UPS and its subsidiaries installed on their trucks and vans for tracking them. In this case the antenna class is a common navigation one.

It's marked Topcon on the top, II Morrow Inc model 590-1114 on the bottom. I've tried searching in all the usual places but haven't found anything yet. If anyone could send anything my way that would be much appreciated!

Looks like an Aeroantenna OEM device. May be a https://www.aeroantenna.com/PDF/AT7530-1_B.pdf The marine style antennae tend to be lower in gain (I assume because the downlead is much shorter), so could be 12dB gain and 5V power.

Hi Just a guess: Single band GPS with a preamp that runs on 12V (or 5V). Gain around 30 db.
