[TowerTalk] Hi Z Sales

[Bill Alexander]

I have the 4 square and it is amazing.
It is my understanding that if he sales the parts and you configure it as a 4 square no one has a complaint, he can not sale as a package, I also agree not to purchase any thing else from DXE. They have lost my business for good.

Apparently the government, at least MITRE, has been
building frequency-independent directional phased
arrays for quite a while now, with voltage probe
antennas, an amp at each antenna and coax delay
lines.

Since the late 1980s or very early 1990s, at least.

Thank you for that schematic.

How can you aim your array east or west, when the west
element has reversed polarity on its transformer?

Am I missing something?
