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:
