Hi,

Thank You for the interest in my LNA problem!

To clarify, I'm going to test the Linrad system, so need the H and V 
channels at the same time.
Unfortunately when I built the antenna (4x9H)  didn't know the importance of 
polarization switching separately for rx and tx.
Now going to upgrade the antenna system to 4x14X.

I have one Icom AG-25 preamp, bying a a second one has two problems:
- pretty expensive
- DC power via coaxial cable

Probably I'm going to build a pair of the nice designs:
