Description
This reduced-height 1/4-wave antenna is ready for years
of use thanks to a flexible internal helical that is
overmolded with a heavy-duty protective jacket. It’s an
excellent choice for outdoor applications or for use in
adverse environments where the antenna must resist
shock, harsh weather, and tampering. HD Series antennas
attach via an FCC Part 15 compliant RP-SMA connector.
