Trimble 57860-20 • GPS Bullet III • 35dB Gain • TNC Connector • Rugged Outdoor Antenna • Replaces 41555-00
New Old Stock, Good Cosmetic Condition

New old stock, in good cosmetic condition, ships in
plain packaging. While these antennae have never been
deployed, they were stored loose in a carton so there
are a few nicks and scratches in the radome surface
(from contact with the other units' mounting hardware)
which have no impact upon the performance of the antenna
or its ability to withstand the elements. Mounting
hardware as shown is incuded (requires N Connector). If
you prefer, you can just mount the antenna on a 3/4" NPT
plastic pipe nipple (not included but available very
cheaply from Lowes/Home Depot etc) with the downlead
terminated in a TNC connector.
Description
The Bullet III GPS antenna is designed for marine and stationary timing applications. It is an active GPS antenna with 35 dB of gain and a single band-pass filter. The Bullets enclosure is all plastic, including the threaded socket in the base of the antenna used for pole mounting. The plastic enclosure is a textured off-white color and is both weatherproof and waterproof. The threaded socket accepts a 3/4" pipe thread for stationary timing applications.

Like the original Bullet antenna, the F-type antenna connector is located inside the threaded socket, which allows the antenna cable to be routed inside the pole and protects the cable connection. The Bullet III uses the same RG-59 antenna cable as the original Bullet.
