G4FPH's Amateur Radio Pages - Aerials
Below is a picture of the 2 element wire delta loop that I use on 20 metres. With only two lengths of wire, one coil, three plastic poles and a 10m tall lightweight mast, it delivers a substantial 'bang to buck' ratio for this band. The direction of fire is due West from the UK and it works well into North and South America and VK-land (via long path).

The success of this aerial has put future use of the quad (below) in severe doubt. 15m and 10m have not been up to much recently anyway!
Below is a picture of the 2 element cubical quad being tuned and tested (on 20 metres). When finished, it will cover 20, 15 and 10 metre amatuer bands. It is an absolute beast to get into the air single-handed! Initial tests were most promising. Pointing it at the US, I could even hear stations using G5RV aerials!

The dipoles for 160, 80 and 40 metre bands are supported by a combination of ex-military aluminium and mother nature! All three dipoles are independently suspended and connect directly to the same coax feeder going straight back to the shack. Click on the thumbnail below for a bigger picture.
