Light Weight Common Connector Dual Band Antenna PA144-432-29-4.5AP

Maximum power input 1000 W on 144-146 MHz with 9 active elements and 750 W on 432-434 MHz with 20+1 active elements.

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

The antenna has 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 is 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.
