Hello all,

I have an issue regarding a turnstile wire antenna, with RHCP. I have built two models that are exactly the same, but they have a different behaviour and that worries me a bit.

When I measure the pattern data, that looks fine for both antennas.

For the Gain my method is the following: I measure separately V.Pol and H.Pol and then I combined the data.
V.Pol is the same (it is alright) for both antennas. However, for H.Pol there is an angle where there is a huge difference between both antennas.

Any idea about what is going on?

Thanks in advance for your time!

Best regards
