It worked quite WELL here.

I have no exact figures but the feedpoint resistance of my antenna was
30-40 ohms depending on WX, all losses included.

- The 160 mm (approx.) steel tube in my well is 12 meters long,
 11m through soil and 1m into the rock.
- Loading coil loss was 6 ohms.
- 40m of 2.5 mm^2 wire laying on the gnd from steel tube to feedpoint.
- Inverted L, 85m long, 12 - 15m above gnd, also 2.5mm^2 wire.
- Vertical part of antenna just a few meters from a tall birch tree (not 
good...)

My signal was "armchair copy" at 100km with only 4 watts of output power.

BTW, I strongly believe in Laurie's "footprint theory".
