A Quad antenna at 33 feet supported by the 20 foot Tower
The modest 20 foot Tower
This tower was originally a windmill tower but it can be built from scratch...
It basically consists of four, 7 metre ( 23 foot ) lengths of galvanised angle iron, 60mm wide and 4 mm thick, a metre of
which is concreted into the ground... The width of the base at ground level is about 1.3 metres ( 4.5 feet )...
The windmill tower was disassembled, refurbished and painted at my home QTH in Adelaide and then
transported 150 kilometres to the Radio QTH near the town of Morgan...
The holes were dug and the tower assembled using new galvanised nuts and bolts...
It was then erected by two of us using a long pole to push it up and into the holes...
Four holes, one metre ( 3 feet ) deep had been dug with the central area dug to a depth of 400mm to allow
reinforcing rod to connect the legs diagonally...
About 2.5 cubic metres of concrete was poured to support the tower...
A concrete base was poured to support the rotator and antenna...
