Topband: HEBA antenna

[Richard (Rick) Karlquist]

No one has commented on the "High Efficiency" "Broadband" claims, so I 
will.  No antenna of this size will simultaneously have both high 
efficiency and wide bandwidth, according to established limits in the
literature.  See K6OIK's Pacificon paper with the latest refinements
to these limits.  Additionally, narrow band antennas typically don't
handle a lot of power.  I doubt that this would be extensible to 50 kW.
not that it matters for ham radio.

When placed over ground, even with an elevated counterpoise, there
would still be ground losses, which would affect efficiency.

Also, although the antenna technically only occupies 1/8 acre, the
fields will be very high within 1/6 of a wavelength, about 50 meters
at 1 MHz.  This covers 2 acres.  I know my 90 foot 160m vertical,
complete with guys, ground screen and top loading wires neatly
fits within a 100 foot radius circle. about an acre.
What's not to like about this?
