This is a two band antenna working on 20mtr and 40mtr Amateur
Radio bands.
The two band antenna (20m
and 40m) radiating elements are fed on the single coaxial cable and the plastic spreader are shown in the
below figure .
Two 34 Feet long wires are taken for the 40m antenna and two 17 Feet long wires for 20m antenna. Both the
live wires are joined at the connector hot end and the return wires are soldered to the ground terminal of connector. The 40m and 20m radiating wires are
separated by the insulating material. Here we have used the plastic spreader of
length 5.5 Inch.
After erecting the antenna the radiator wire length need to
be adjusted for best SWR. Typically 1.2:1 is achievable.
We will be adding photos soon after tuning.
