Interesting 160M Antenna QST

[flintstone mop]

There's a nice 160M antenna project in this month's QST.
Using 450 ohm ladder line. It gets good if the main support is over 60 feet high.
Two wires connect to each of the free ends of the window line at the top and are about 50 feet long. They form the shape of an "A" coming back down.
 
The bottom of the window line is joing together and is in series with a VAC cap to the center conductor of the coax. The shield connects to 1/4 wave radials 40 ea min.

Initial tuning with VAC cap and pruning the ends of the two wires from the "A". You need an analyzer and try to get to a '0' reactance.
Anteanna was modeled and the author claims it's a good low angle radiator for the small lot owners who want to get on 160M

i saw that article too but did not read it.  seems like one may as will put up inverted L or T.  I have a problem with the top part sloping down.   when antenna wires change direction angles should not be less than 90 degrees (my gut feeling).

There was an article in one of the pre WW2 RADIO Handbooks describing an antenna that was a 40m end fed zepp, up about 65 feet. On 160, you tie the feeders together and feed the whole thing as an inverted L, against a radial ground system.  The open wire line serves as the vertical part of the inverted L.

It would probably work well as an 80m inverted L as well.
