Optimal output on 80 and 40m because the full length of 9.8m is used on both bands. Optionally available is the "TLK" top loading kit for better bandwidth, as well as extension kits for 160 and 30m.
Included with the antenna is a 1¼" base tube (60cm long). The antenna requires a radial system, e.g. the Butternut GRK ground radial kit.
