15/20/40m WIRE DIPOLE "UN7JOT" version 2



It's the same UN7JOT triband dipole ( link to the first version ),there's only a different center support and a different positioning of the choke.

I've used a perspex disc (7 cm in diameter,1 cm thick ),where I've installed an SO239 connector, together with the two dipoles (20m and 15/40 m).

The choke (few turns of coax cable),is now strapped to the support pole.

Like in the first version,I've decided to keep the support rope,that act as a guide line for the 40m dipole,in order to minimize the strain on the wire.
