This is my homebrew vertical antenna for 40m and 20m.

Here we have a 10m (in length) fibre glass pole with 10 metres or 1.5mm pvc coated cable running up it.

The same for the 5m (in length) vertical..

Outer braid of coax is connected to an earth rod and 4 radials. Two 5m and Two 10m radials in length.

After recording this video I worked VA2PW in canada so I'm pretty chuffed my homebrew works ok!

This antenna seems to be resonant on 40m but swr on 20m is about 1.7 but using the internal ATU on my FT-450 brings this down.

I will be playing with the length of the 5m cable to try and make the 20m element more resonant.

73's for now...
