Has anyone stumbled across the 12V antennas for Symmetricom 2500 Time Source units. The basic 23 dB model was a Symmetricom 112-00001-02, furnished as part of the 093-03110-11 kit.


They also offered a 40 dB model, 112-00008-02 with the 093-30110-12 kit and a 50 dB model, 112-00008-03 as part of the 093-30110-13 antenna installation kit.


I have never seen noticed any of these offered on eBay, even though the model 2500 Time Source (with its SRS PRS-10) is now obsolete. It appears antennas may have been left behind on the roofs when these installations were upgraded.

I have one, Bruce, do you have questions about it? They are readily
available. Search on

TELECOM SOLUTIONS TS-3500 090-71010-87

It says TS-3500 but the same part is used on the 2500.

I have a Symmetricom "Replacement GPS Antenna Kit" P/N 142-614-50 which
consists of "one wide range 5-12 VDC L1 antenna" and 50 feet of Belden
9104 coax terminated with a BNC.  Plus the hardware and stub mast to fix
it to a vent pipe or similar.  I don't know what system this antenna was
designed for but the 5-12V spec is interesting.

Note that many Antcom antennas are 2.5 to 24VDC...
