Hi: I just got an Ashtech Z-12-R Reference Station and it needs the subject antenna. http://www.prc68.com/I/AshtechZ12.shtml I've got a bunch of GPS antennas but none with the needed combination of features. It would be good to learn which antennas are 10 Volt types. For example is the Trimble 4000ST L1 Geodetic, Model 14177-00 a 10 Volt antenna? http://www.prc68.com/I/Trimpack.shtml#4000STant -- Have Fun, Brooke Clarke http://www.prc68.com

You could put a regulator on the voltage line for the antenna so that you could use a 5 Volt antenna. This would get you away from the specific voltage requirements for their antenna. 73 Glenn WB4UIV At 09:54 PM 5/20/2009, you wrote: >Hi: > >I just got an Ashtech Z-12-R Reference Station and it needs the >subject antenna. http://www.prc68.com/I/AshtechZ12.shtml > >I've got a bunch of GPS antennas but none with the needed >combination of features.

Hi Glenn: Yes, I've thought about doing that, but then priced a small Pomona box at $50 and thought just getting the proper antenna would be easier and not that much more money.

Hi Brooke, Check Ebay # 270386792376 & #200243560108 They are probably dual frequency splitters. Then you connect your Z12 to a DC-block port and either just DC-power or a fitting GPS receiver to power the antenna through the DC-through port. http://gpsnetworking.com/GPS-antenna-splitters.asp http://www.gpssource.com/mysql/splitters.php Both GPS Source and GPS Networking splitters surface on Ebay from time to time. The HP/Agilent/Symmetricom line of splitters are L1-only. -- Björn > Hi Glenn: > > Yes, I've thought about doing that, but then priced a small Pomona box > at $50 and thought just getting the proper antenna would be easier and > not that much more money. > > Have Fun, > > Brooke Clarke > http://www.prc68.com > > > > Glenn Little WB4UIV wrote: >> You could put a regulator on the voltage line for the antenna so that >> you could use a 5 Volt antenna. >> >> This would get you away from the specific voltage requirements for >> their antenna. >> >> 73 >> Glenn >> WB4UIV >> >> At 09:54 PM 5/20/2009, you wrote: >>> Hi: >>> >>> I just got an Ashtech Z-12-R Reference Station and it needs the >>> subject antenna. http://www.prc68.com/I/AshtechZ12.shtml >>> >>> I've got a bunch of GPS antennas but none with the needed combination >>> of features.

Thanks Björn: I've got both of them on order and it's a way to start using the Z-12. But my L1/L2 antennas are military patch types and for the Z-12 I'd like to use a geodetic grade (ground plane or choke ring) antenna long term.
