After a long preparation time, a lot of gardening work and a failed attempt to set up the 8 m mast, the double delta antenna is ready and waiting for the connection of the balun / resistance box and the coax cable. As soon as the weather permits, initial tests can be carried out.
The DDA is suspended from 2 guy points at a height of approx. 6 m. A compromise already resulted in the suspension. Anchoring points 8 m high were not possible because a mast bar could not be set up in this length. The horizontal wires run 1 m high. It is fitted with a 16: 1 balun. A terminating resistor has 1 kOhm. The resistor sits in a fuse holder and can be easily replaced with another if necessary. The total scope of the DDA is approx. 78 m. The targeted receiving direction at approx. 325 °. By using quick-change termination boxes, the DDA can also be quickly changed to approx. 155 °.
