I am trying to understand what appeared to be a faulty LHG antenna with one polarity ! ( screenshot with -88/-72 Ch1)
We tried 2 other LHG antenna's and exactly the same issue with the others, We raised the hight of the antenna and there was no issue with fresnel zone clearance,
Finally we tried a high gain LHG XL (screenshot with -61/-61 on Ch1) which solved the issue!
Can someone explain how this can occur, Higher gain antenna has a narrower beamwidth but why is the LHG antenna's effected so much on one polarity?
