Homebrew AS-2259/GR NVIS Antenna By N3OC - Fracassi
Homebrew AS-2259/GR NVIS Antenna By N3OC. The AS-2259/GR is an NVIS (near vertical incident skywave) military Antenna for short to medium range communications on the lower HF bands. It has been made over the years by several manufacturers, and when available, they are usually somewhat expensive. This is pretty much the same Antenna as the Collins 637K-1, the Telex Model 1990, and the Harris RF-1936. The ionosphere generally supports NVIS communications at 10 MHz and below. At frequencies above the critical frequency (CF), the signal never returns to earth.
