432XP50圆极化八木天线专为EME地月通信、卫星通信和长途对流层散射用途而设计。双极化的灵活性对于长时间等待中消除法拉第极性旋转的EME特别有价值。为卫星通信和长距离对流层路径提供极性灵活性也是非常有用的。这种极化灵活性也可以处理由于丘陵、山地人和建筑物而产生的极性变化，更不用说工作的移动电话和具有垂直方向的小型电台了。
432XP50圆极化八木天线的增益和前向后向比（F/B）非常好。天线的方向图非常干净。
为了使天线的噪声温度与当前流行的低噪声前置放大器相匹配，该方向图非常重要。使用单只432XP50、两支或四支八木天线组成的天线阵列都是一个非常小、易于管理的组合，即使使用像Dxpeditions这样的非常普通的电台，也可以进行月球地（EME）天线！
The 432XP50has been specifically designed for EME, Satellite and long haul tropo-scatter use. The dual polarity flexibility is particularly valuable for EME where the long waits for Faraday polarity rotation are eliminated. Having polarity flexibility for Satellie and long haul tropo paths is very useful as well. This flexibility handles polarity shift due to Hills, mountians and buildings, not to mention working mobiles and modest stations with verticals. Gain and F/B are excellent. The extremely clean pattern maximizes forward gain and F/B. The pattern is important in order to match the antenna’s noise temperature with modern low-noise preamps. Using the 432XP50 in and array of two or four antennas is a very small, manageable package that can make moonbounce (EME) contacts even with very modest stations like Dxpeditions!
The driven elements areCNC machined aluminum,O-ring sealed connectors assure low maintenance and long-term peak performance. Internal connections are embedded in a space-age silicone gel that seals out moisture and improves power handling. The 3/16” 6061-T6 rod elements are centered in the boom to minimize polarity interaction. Insulators are UV stabilized and locked in place with stainless retainers. The central boom section is 1-1/2" dia., tapering, front and rear,through 1-1/4" sections to 1" ends. A built in, non conductive vertical mast and Dacron cord supports the boom., M2 can supply all the parts for arrays of any size. M2makes the HPR-1, high power relay for polarity selection.M2 makes the best switching and non preamps using the latest device technology. See web site for more details.
