Ve6fi Amateur Radio





I built the K9AY receive antenna from 1.5 in AL pipe and 1.5 ABS pipe at the top where all the wires pass through.  The anchors are pieces of 1 inch pipe about 18 inches deep.  I did not terminate the wires directly on the relay box at the bottom.  I terminated or anchored them on a piece of fiberglass angle. This makes the attachment point a bit more robust.

The transmission line back to the shack is 75 ohm 7/8 inch cable. |In the shack there is a controller which which change the direction of reception in four directions.  I used a control cable with six wires in it.  The base at the tower has a low level amplifier that can be switch on and off from the shack.  This particular unit was sold by Array Solutions.
