The PROGRID403-18-N4 is designed to meet the demanding requirements of a professional grade, half parabolic antenna.

This antenna provides 18.5 dBi gain across the operating range of 806-896 MHz with a VSWR of 1.5:1 or less.

This rugged unit is manufactured using only high strength 6061 T6 aluminum; all grid components are fully welded to ensure continuous optimum performance in the most severe operating conditions. The grid is shipped fully assembled.

The directive feed element is easily installed and permits either Vertical or Horizontal polarization. (A selection of tuned feed elements is available, providing a choice of different operating frequencies utilizing the common grid. Contact Sales for your specific application requirements)

The design incorporates a 5' integral feed cable allowing ease of installation and ensuring long-term dependability. The antenna is finished with black powder coat to protect against environmental degradation.
