The PROGRID138-10 is designed to meet the demanding requirements of a professional grade, severe duty directional antenna combined with the added advantage of a low profile reflector antenna.

This antenna provides 10.6 dBi gain and operates effectively across the operating range of 138-174 MHz with a VSWR of 1.5:1 or less.

This extremely rugged unit is manufactured using only high strength 6061-T6 aluminum and is fully welded to ensure optimum performance in the most severe operating conditions.

The dual-dipole design incorporates a 5' integral feed cable allowing ease of installation and ensuring long-term dependability. The antenna comes fully assembled so all potential intermod or misalignment problems are eliminated. Both dipoles are finished with Type III (hard) anodizing.

All other components are treated with a black thermoset polymer to ensure many years of dependable service.
