Description
The VHF 136–174 MHz 3 dB Omnidirectional Ground Plane Antenna is designed for fixed VHF communication installations that require dependable RF coverage across the 136–174 MHz frequency range. With a 3 dB gain, 50-ohm impedance, vertical polarization and a 360° omnidirectional radiation pattern, the antenna is suitable for applications where communication coverage around the installation is required.
The antenna operates throughout the 136–174 MHz VHF band and has a maximum specified VSWR of 1.5, helping provide suitable impedance matching for compatible 50-ohm VHF radio equipment. Its ground-plane configuration is intended for fixed installation and can be used with VHF communication systems where an omnidirectional antenna is required.
Typical applications include VHF base stations, two-way radio communication systems, industrial communication networks, infrastructure communication, public-safety communication installations, field communication systems and other fixed VHF radio applications operating within the specified frequency range.
The antenna features vertical polarization and a 360-degree radiation pattern, making it appropriate for communication requirements where signals need to be distributed around the antenna rather than concentrated in a single direction. The specified termination is N-Type PL-259 female, as provided in the product specification.
For installation, the supplied double clamp with nut and bolt provides mounting hardware for the antenna assembly. The manufacturer specification also states a 1-year on-site OEM warranty.
This VHF GP antenna is a practical choice for organizations looking for a 136–174 MHz omnidirectional antenna for fixed VHF communication infrastructure, subject to compatibility with the radio equipment, mounting arrangement and installation environment.
