HYS UHF VHF 2m 70cm 21in NMO Antenna - Durable Mobile Radio Mount

Our review of the HYS UHF VHF 2m 70cm 21in NMO antenna finds it best suited for vehicle mobile radio users who need a simple, tough install and reliable reception on both VHF and UHF bands. The single biggest reason to buy is its combination of a true NMO mount, a 13ft RG58 cable terminated in a PL259, and a stainless steel L shape fender bracket that makes mounting straightforward and corrosion resistant. Installers get a ready-to-use mobile antenna package without hunting for separate mount or cable parts.

Key Features

• Dual-band operation: Covers 136-174 MHz and 400-470 MHz so the antenna works for common 2m and 70cm mobile radio channels.
• NMO mounting: The NMO connector on the antenna and mount lets users fit it to compatible bases or use the included stainless steel fender bracket for a secure vehicle install.
• Long RG58 cable with PL259: A 13ft RG58 coax with a PL259 UHF male connector provides ample reach from roof to dash-mounted transceivers without extra adapters.
• Robust construction: The stainless steel L shape fender bracket resists corrosion and deformation for dependable mounting on trucks and cars.
• Moderate power handling: Rated to 100 W input, the antenna is suitable for most mobile transceivers used by hobbyists and professionals.
• Compact length: At 21 in the antenna keeps a low profile compared with taller whip options while still providing usable gain.

Who It's For

The HYS 21in NMO antenna is aimed at amateur radio operators, truckers, and mobile radio users who want a straightforward install with a complete kit: antenna, 13ft cable, PL259 termination, and a stainless steel fender mount. It is particularly useful for people who need both VHF and UHF coverage from a single antenna and want corrosion resistant hardware for long-term vehicle use.

Those who need maximum long-range performance on a specific band, a very low-loss cable such as LMR series, or a different mount style should look elsewhere; this package prioritizes convenience and durability over ultra-low coax loss or the very highest gain figures.
