Hi Zack,
I have 4 Cushcraft 17B2's that I have had in EME operation since the CW days
back in 1990's.
There "may" be better designs these days but they have garnered me WAS and DXCC
on 144 MHz.

Hi Joel,
What kind of antenna system are you using on 144 MHz?
Bob KH6O (now an SK) had a large array of helical antennas for EME on 432.
It looked like a giant box spring. He sent me some photos years ago.
