Hi Andrew, That is exactly to be expected. 435.300 MHz is RHCP and 435.150 MHz is LHCP.

Gudday

I tried a crossed offset yagi on the one boom.

When I threw just one part of the yagi on the boom, AO-51 was really good,

Now I am finding that with the second yagi on the boom I am seeing a big drop between 435.300 and 435.150 voice / data.

I think I might remove the second yagi from the common boom and add it to

a

new seperate boom

Comments ?

I think I am getting -20db due to the cross polar RHCP LHCP with the data

The voice is great , the data is down in the mud
