Hi Chuck,

In the early 90's, Doug DeMaw had a piece in QST called "The Beverage
Antenna Re-visited" (or SOMETHING like that, anyway!)...

As part of the piece, I recall he had an insert on his personal experiences
with a very long Michigan Beverage in the 50's --- in that part of the
article, I believe he referenced using the toroid core out of an old TV set
picture tube deflection yoke coil for the foundation of his matching
transformer...

In any event, that's the very thing I did with my first Beverage here some
time ago. I've since replaced that antenna with a switchable array of K9AY
loops, and I've used the same core material for that set-up. In fact, I
wound de-coupling coils for the feeders of the K9AY loops, too, using ---
again --- the cores from these old TV relics.

One thing for sure, Chuck, the price is certainly right for these
cast-offs --- the only hassle is removing all that heavily-enamelled copper
wire that encases the cores...but it's well worth the effort, I think...
