The most important asset of any amateur station is of course the aerial, however living in an urban environment the space at my QTH is restricted to back garden operation.

The size of which is approx (everything I do is approx) 25 feet wide X 35 feet long, and to make matters worse the ground slopes away from the main building (shack).

Many assorted vertical arrangements, wires and dipoles have been tried with varying degrees of success and failure, but the present arrangement works reasonably well on all HF bands 160-10 metres. It consists of a simple 28 ft horizontal copper wire, matched courtesy of the SGC 230 Smart Tuner atop a lightweight 5 section  lattice tower  which is painted olive drab.

This picture was taken early Spring, and I think you will agree the camouflage works quite well! In the Summer the surrounding trees form a heavy screen almost 360' around, and this inevitably also reduces the effectiveness of the aerial.
Being located on the side of a hill (the same ridge as the Greenwich Observatory) the ground conditions are that 1 meter subsurface is a layer of gravel, which although moist is not a good reflector, and it's not known how deep the water table is.
Although the SGC230 achieves a good "match" every time the effective radiation characteristics change with the weather and soil conditions, etc.
