Topband: DX-Enginneering Active Antenna System

[Mike Waters W0BTU]

Hello Joe,

I appreciated your post.

You said that "The "phasing" part of the W8JI design was on Tom's web site for a very long time."

Sounds like it isn't there any more; do you have a copy of it, or at least know what page it was on?

Thanks!

73,
Mike Waters
