Antenna

General Description

The UA864 antenna provides active directional RF coverage in an easy-to-install, low-profile enclosure that can be 

mounted on walls, ceilings, or metal surfaces with improved reception. The paintable, neutral white housing allows 

the antenna to blend into corporate or classroom settings. The 4-position selectable gain switch provides attenua-

tion and boost settings to match the antenna to the environment. UHF variants provide wideband RF coverage.
