Light Weight construction with common connector for both bands with very handy boom length of about 4.4 meter. Does not need guy rope support for stationary use. Because of quality construction with easy assembling, this antenna is suitable for portable use and two band contesting with one transceiver. Two or four antennas in stack are very efficient for competitions and EME communications. Easy Moon Bounce on single call and on both bands.

Antenna have been calculated using state of the art full 3D Electromagnetic Simulation Software including the influence of the boom, bracket, baluns and connectors. The performance of the antenna designed using these techniques are exceptional, far better than any antennas designed using “wire” programs like EZNEC Pro/4 – NEC v4.2 or NEC v5.0, 4NEC2, MMANA or AO.
