Product Overview

Southwest Antennas Part # 1001-178 is a half wave dipole omni antenna with a frequency range of 1,250 - 1,850 MHz and 2.05 dBi of peak gain. This product features an integrated GPS band notch filter inside of the antenna to help prevent radios utilizing this antenna from impacting co-located GPS receivers.

1001-178 features an integrated 3" RF Gooseneck with black chrome SMA(m) RF connector, which contributes to the improvement of RF link margin and overall antenna performance. Our proprietary antenna design and manufacturing process ensures optimum antenna RF performance.

The SMA(m) RF connector can be easily secured or removed from equipment in the field by a single gloved hand, no tools required.

Antennas with integrated RF Goosenecks are ideal for handheld video receivers, portable radio systems, or any other mobile communication platform. The RF Gooseneck can be threaded through MOLLE gear or other tactical vest hardware for added security while moving.

A rugged flat black fiberglass radome provides protection from damage and gives the antenna a low visibility finish. The integrated RF Gooseneck allows the antenna to bend and deflect away from impacts during indoor or outdoor operations.
