Don,

Took me forever to put the antenna together. The instructions aren't Ikea easy.

Page 4 step 9.

If I am not mistaken, to get LHCP you should swap right with left -> Driven Element Block mounts to the LEFT hand side of the boom.

For desensing I added a Comet Duplexer CF-416 between the antenna and the preamp in an enclosure today (with the low pass unconnected). So far so good to get rid of my desense issue with both antenna configured for RHCP.

I am assembling my new LEO pack, and the instruction manual for the 2M antenna tells you that you can change from RHCP to LHCP by repositioning the driven element and phase line.

The 70CM antenna however does not have this ability explained in the manual. I have asked this question of M2 but haven't heard back yet.

If possible, I would like to have the 2M antenna configured for RHCP and the 70CM for LHCP to minimize any desensing.

The antennas will be up about 80 ft on top of my tower, so I would like to get this configured correctly the first time so I don't have to bring the tower down.

Does anyone have any experience changing the polarization on the M2 70CM antenna in the LEO Pack?

73,
