Someone asked about link coupled antenna feed.  The Mosley S-402 40 meter 
beam uses a big loading coil in the center of each element and is link 
coupled by a wire around the driven element coil at several inches out. 
Carl Mosley(SK) wrote a paper on link coupling 40 years ago or more showing 
how effective it was.

Most old timers used the same type coupling to attach a scope to watch their 
modulation from a transmitter.

The Mosley beam works well but my Cushcraft 402CD is better.
