The SuperLoop 80 is a high performance, full size, full wave, 80m loop antenna. On 40m it is a 2x wave length open loop or Bi-Square. The stub in the top leg of the antenna opens the loop when operating on 40m and selected other bands. This improves the antenna's radiation pattern. Its gain is around 4dB, but it will seem a lot higher due to its excellent, low angle, radiation pattern. The overall length of the SuperLoop 80 is 34m (112ft) with the HD ladder line switching stup 9m (30ft). The 50 Ohm coax from the dedicated matching unit to transmatch is not critical but recommended to be 1/2 wave length. Coax not supplied with antenna.
