My QTH  

Most of the wires you can't see as they are burried about 5 cm below the surface. Ca. 1.5 Km copper wire is used to get a reasonable ground counter- pole as the ground conductivity in most places of Sweden is very low.
This gives at least an acceptable low ground impedance, but doesn't help too much to decrease the radiation angle on the lower frequencies of course. A slight improvement was the result of this artificial ground on 80 mtr DX, using the sloper system.
The self-supporting retractable tower is ca. 21 meters high, on top you see the Cushcraft X9 and a 5.5 mtr stacked 2 mtr / 70 cm vertical.

In July 2004 I replaced the X9 with the mechanical tunable /computer controlled 4 el. Steppir antenna. This is a very innovative design and performs as a monobander at resonance at every frequency between 14-30MHz. Making it a resonant Yagi at 'all' frequencies also keeps the F/B and gain almost constant and makes it an almost perfect 50ohm resistive match. Hence, the top of the tower looks now like this:

The tower itself is successfully used as a vertical for topband. Look here how I matched the tower for 160 meters. Other antennas are a delta-loop for 80 and a separate one for 40 mtrs.
The whole area is scattered by tall trees which makes sat. tracking or even just sat. TV quite tricky. Last summer I cut down several birch trees only to get a narrow opening for some sat. TV dishes.
So, I have to save my interests in EME for another time and leave mother nature just as she is..
