Sold Out - Backorder Available
The 20-40-71 consists of a high strength, low loss cylindrical glass/epoxy radome containing a vertical array of four co-linearly stacked dipoles combined in such a way as to maximize radiation in the horizontal plane (0° elevation).
The array is end-fed enabling the antenna to be ground-plane independent.
The entire assembly is foam filled for long term environmental protection. It has an N type (female) connector and a 2 inch diameter metal fitting to enable mast-head mounting.
- Suitable for mast head mount
- Covers full JTIDS band
- Pattern optimized for highest gain at horizon
- Less than 4.5 feet overall height
- Rugged design for MIL-STD-810 environment
- At least 1 kW peak power, 500W CW
- Interchangeable with NSN 5985 01 443 0282
