ESE ES-ANT Active Multi-GNSS Antenna

The ES-ANT is an active, multi-GNSS antenna that drops in as a direct replacement for the standard GPS antenna on an ESE master clock when the installation site has heavy RF interference or a marine environment to contend with. A 40 dB active amplifier stage and 50 dB minimum filtering at plus or minus 50 MHz keep out-of-band interference from swamping the GPS signal before it reaches the receiver.

It mounts with a screw-mount bracket and connects over a 19 ft TNC-to-TNC cable, drawing 2.7 to 10 volts and 25 mA maximum from the master clock it serves. The radome measures 2.6 inches in diameter by 2 inches high and is rated -40C to +85C, which covers rooftop and outdoor installs as well as the marine and industrial sites it is built for.
