Pagoda Antenna - RHCP v LHCP

Should be a nice quick one.   I';m going to order a set of these antenna.  I';ve determined I need SMA, but there';s a choice of RHCP or LHCP versions.  I presume RHCP refers to a right hand thread direction and LHCP means left hand, yeah?  If so great, but what does the CP bit stand for?  Had a good Google and I can';t find reference to it anywhere.

RHCP - right hand circular polarised
LHCP- left bla bla bla

It refers to the orientation of the lobes on the antenna, and thus the orientation of the signal, you need to use the same orientation on the Rx and tx.

There is no real difference between the two, rhcp is most common.
If two or more pilots are in the air, using different polarisation will reduce interference between signals

VooDoo

Great, I';ll get some ordered.

Once again, thank you for sharing your knowledge.
