Hi all,
After some info from someone with experience or knowledge in this area, rather than just hearsay or speculation, please:
If I have two radios, one horisontally and one vertically polarised, I know the interference between them is minimal so you can send two signals on the same frequency, with different polarisations.
How does this work with linear vs circular polarisation (my proposed setup)? In particular, a diversity linear vs circular (ie a spectrum transceiver with 3 satellites in each axis and a circular antenna for other stuff).
Assume for now that the powers of each radio are identical (eg 10mW), so one wont overpower the other.
Cheers,
Simon
PS: For completion, other people may be interested in interference between RH-circular & LH-circular, if this is in the knowledge bank!

It won't work.
Linear vs. circular has only a loss of -3dB so if you use two different sets of radios/receivers on the same frequency you will have a lot of interference.
Also: linear vs. vertical polarisation on the same frequency will interfere with each other too, but not as much. I don't think this will work either. especially if you are on the edge of your range.
