When it comes to right hand and left hand antennas
I know I should stick with one or the other
So if the antenna that’s on the quad is rhcp then the one on my goggles should be the same...
Yes, stick with RHCP, any polarized antenna will work with like polarized antennas AND linear dipoles. If you end up flying with a bunch of others then a LHCP set for the goggles and quad could be a benefit, but as an example, I have an LHCP set and I have only used it once to test it. If one day you find that you are flying or racing with a bunch of other pilots all the time, then maybe invest in an LHCP set to give you more rejection of the others signals, but if you can stay 20-40 MHz away from others frequencies you should be good to go.
