From top of a fire engine, ladder 30m high, viewing towards Japan 30 degrees

from a hotel room

look at it at google earth and count my neighbours and noisemakeing industry :-)

the grey area is from my neighbours, the white one is mine


Tower is 3 sektion motorized crank up tower with 20m height.

On top is a Optibeam 17-4 17 element 4-bander ( 3element on 40m, 4 el on 20m, 4el on 15m and 6 el on 10m )with 11,8m Boom 100kg
and a 9el 2m Yagi DK7ZB style.
I worked on 2m: OZ, LA, PA, G, GW, EI, GM , F, OE, HB9, OK, OM, ON, SP
( and S5 via Aurora)



160m is covered with the 24m tower, with omega feed system.
There is galvanized fence under the tower. Let's say 20m by 35m.
I have to add longer radials, I know.


I am working on a 80m 4 square for many years and still have not finished.

meanwhile (January 2011 I have two fullsize elements NE and SE and two loaded elements NW and SW ( those at the building)

For 40m I am also working on a 40m 4 Square. Yet, I have all four verticals installed and just need to connect the cables to my Comtek 4 Square Controller . Four steel post are 1m deep in concrete and 2m above earth.
Then I mounted wood posts each 5m long to them. The alloy tubes are mounted on the wood post with plumber mounts. The Verticals are fullsize. I will have to try to find the best scheme for the elevated radial layout because the garde ist not wide enough in that area to hang radials to east and west. Have a look on the map above. Email me if you have an idea what might work best in my situation.
The feed points are at 2m/6ft above ground. Under each vertical are 4 elevated radials. On the grass is galvanized chicken fence.






For better lowband-receiving I have a K9AY
with galvanized chicken fence under the two loops.
I also use a 160m long two-wire beverage switchable for east and west direction.
But on a city lot there is always a higher noise floor.
