I think the 'cage' type antenna - where several conductors are spaced in
a long cylinder-type arrangment using circular spreaders, was originally
called a "Marconi" type antenna. A friend here in Northern Nevada, where
the weather is certainly a factor - has considered a dipole using 4"
aluminum irrigation pipe - suspended on 5/8ths or 1" nylon rope inside the
pipe - but he's afraid that a a few inches of ice in an 80-mph wind might
BTW, the Marconi, Beveridge, and other 'aerials' are from the days when
"Amplitude Modulation" meant putting a (huge) carbon microphone directly
in the primary of the "transmitting coil" - basically you'd be talking
(shouting) into a mic connected dirctly to your high power tuned Tesla
I, for one, much prefer 833s, 405s, hell even 4CX30,000s.....
Cheers and Best of the Season
PS: Any 80M weekend QSOs planned? Time to burn the dust off the 6146s in
