Product Description

For public safety and LMR fleets working across multiple UHF channels, the A15HD450WBB provides no-tune coverage from 380 to 520 MHz. The wideband response can reduce antenna changes when radios must operate across different portions of the supported UHF range.

Installation conditions affect matching: VSWR is below 2:1 with a ground plane and below 2.5:1 without one. The integrated shock spring, stainless-steel whip, and −40°C to +80°C operating range support exposed vehicle use without adding unsupported environmental ratings.

Ideal applications: law enforcement vehicles, public safety communications, and mobile UHF LMR systems.
