Product Overview
The 174-862MHz VHF UHF DTV FM Car Antenna is designed for vehicle-mounted digital TV and FM radio reception. It operates across VHF 174-230MHz and UHF 470-862MHz, covering two commonly used broadcast frequency ranges in one retractable antenna.
The antenna provides 5dBi gain with a VSWR of ≤1.5 and a 75 Ohm impedance. Its telescopic antenna rod can be retracted and extended as needed, while the magnetic base allows the antenna to be mounted on a vehicle roof without drilling.
A standard RG174 coaxial cable is supplied with a length of 1.5±0.03m. Custom cable lengths are available for different vehicle installation requirements.
Application Scenarios
This magnetic base telescopic antenna is intended for vehicle-mounted DTV and FM radio reception where coverage of both VHF and UHF broadcast bands is required.
