If you have one of the Symmetricom GPS Clocks with a BNC antenna jack, you'll probably know that the antenna supply voltage is (unusually) 12 Volts and that if you connect to your receiver a generic GPS antenna such as those most commonly sold on eBay you'll damage the antenna as almost all other antennae expect only 5 Volts of power. If in doubt, measure the voltage across the the antenna connector on your receiver. If you see 12V then you need one of these antennae.
Here's a chance to pick up an antenna that is specifically matched to the needs of the Symmetricom time servers.
The general specifications for the 142-614-xxx antenna are:
- Size: 2.625 in diameter x 1.5 in (6.67 cm dia x 3.81 cm)
- Weight: 0.55 lb. (0.250 kg) (including mounting mast)
- Operating Temperature: –40°C to +70°C (–40°F to +158°F)
- Storage Temperature: –55° to +85° C (–67°F to +185°F)
- Humidity: 100%25 condensing
- Power: 25 mA @ 12 V (supplied by the receiver)
There's a TNC connector on the underside of the antenna capsule. The cable connection is protected from the elements by two O-rings which keep out the elements. The mounting skirt is held in place by four small Phillips screws so no special tools are needed. Usually these are mounted to a convenient vertical structure with a full view of the sky using a couple of worm-gear type hose clips.
