Hello Mike,

I believe that gamma-matching a very short antenna also introduces a
practical problem as the feedingpoint impedance will be extremely low
(probably some milli-Ohms). Apart from problems with the impedance
matching, the current at the feedingpoint will be extemely high.

When I thought about this suggestion again,  I realised that it would match
the antenna OK, but of course it would not help to resonate it. Gamma
matching is a good way of feeding a grounded resonant Marconi, but it is
still necessary to use top wires to bring the vertical to resonance. Back to
the drawing board . . .
