Twin lead Marconi to the rescue

[N6YW]

This was sent to me by my friend Jim K6SXD. It may be the only way I will get my station
on 160.

..this makes no sense...if you have the space for 125-130ft of  wire, just run 1/4 wave on 160 (125ft) feed it with coax, and attach a ground system to the ground side...i see no advantage to this...and this is not a marconi anyway...

Tim is correct. Just put up an inverted-L and a lay down some radials.

  The antenna as shown was in an old Bill Orr book. So increasing the feedpoint impedance 4X over a just a wire antenna of the same length would decrease the ground current 2X. That is a 6DB decrease in ground loss in my book, and when the Z with a single wire is low, like 10-15 ohms, doing the 4X impedance transformation gets you up near 50 ohms. I guess this is like 1/2 a folded dipole.

YMMV.

Oh, an antenna that is a DC short has some advantages as well over the single "floating" wire antenna.
