Thank you for reading this.
Ten years ago I built a pair of circular polarised aerials primarily for satellite use. The UHF aerial has 12 elements in each plane while the VHF aerial has 6 elements in each plane. My UHF received signal strength often seems to be below that of other stations and so I'm rethinking how I have set up these aerials. The received signal strength via VO-52 is S7 at the best, without a pre-amplifier, and so I'm happy with that. The UHF aerial is where the problem is even thought they are set up in the same way.
Both aerials are mounted in an X orientation. One set of elements is a quarter wave ahead of the other set. Because of the X mounting I cannot tell if the vertical set is ahead of the horizontal set or not. Each aerial is fed via a power splitter via equal length cables.
My question is; does this sound like a correctly set up right hand polarised aerial? Originally I thought it was now I'm not sure.
