Topband: "T"-Top Vertical Antennas

[Paul Christensen]

> "Paul, There's still some discrepancy here.  I have the Radio Club of
America commemorative publication on the 1921 tests.  In it
Amy and Burghard describe the station antenna:..."

Going back that far, there's bound to be some discrepancies about the 1BCG 
feed detail, but several references point to a "T" feed.  In fact, the same 
Radio Club of America website describes: "the antenna system consisted of a 
"T type cage with a 100 foot flat top 70 feet high."  Reference to the "T" 
would imply a center feed and not an end feed as implied by Amy and 
Burghard.

I've seen several photos of the ground detail, and just one of the antenna. 
Try as I could, I cannot locate where it is to take a better look at it. 
I'll keep searching my materials to see if there's a better photo of the top 
portion.

Incidentally, beginning on p. 52, Edmund Laport discusses early use of 
elevated radial counterpoise systems in "Radio Antenna Engineering."
