Hello Sion
it is easier then you think, i made it also with a relay as M² does, i use a Tohtsu 120 coax relay on 1 off the 2 directors. Just switching the CENTER conductor at 1 director changes the polarisation; without a relay, just turn 1 dipole opposite so the center conductor is on the other side of the boom,this gives the other polarisation; you can buy a switch from M², but very pricy for +-1m alu element, 1 relay in a alu box i made myself that switches, and works FB; i also made a 4pol switch for 2m and 70cm with 4 cx-120 types per box, but on 70cm i gonna change them into 4 SMA relays i found on a hamfest, they have less loss.

Dear All,
We are trying to setup determine how to setup the M2 436CP42UG & 436CP30 antennas for fixed LHCP polarity. However the manual only provides instructions for RHCP.
Tried to Google this up but failed to find any information too. Any pointers or advice will be greatly appreciate.
Thank you.
73, Sion, 9M2CQC
