The PCTEL Low-Band Quarter-Wave Antennas are high-performance mobile antennas designed for low-band VHF communication. These antennas are engineered to provide reliable and efficient radio signal transmission, making them ideal for public safety, emergency services, transportation fleets, and industrial applications that operate on low-band VHF frequencies (typically 30-50 MHz or similar ranges).

A quarter-wave antenna is a type of monopole antenna where the length of the antenna is one-quarter (1/4) of the wavelength of the operating frequency. This design allows for efficient radiation and reception of radio signals, making it a cost-effective and reliable choice for low-frequency communication.

PCTEL’s low-band quarter-wave antennas are designed to be mounted on vehicles, base stations, or other fixed installations, ensuring strong signal transmission over long distances, even in challenging environments.
