QRPGuys 80/60m Vertical Antenna

This will be used on 80m QRP as M1K in the RSGB IOTA contest 2018 from EU011 St Agnes.

It is going to basically be a centre loaded GP on 80m.

The last contest on 80m was from C6 and from there I had two full sized phased 80m verticals. Wanted to work loads of G stations, this time I'm 4000 miles closer so this should do fine :-)

Of course I know from St Agnes looking West I have nothing but salt water path to NA.

Propagation might be metaphorically in the toilet but I suspect a contest will test that hypothesis.

Anyway as the build goes on I will add to this post. As per the 40m-10m UnUn there are no antenna wires, I'll add this a bit later as that will need me to get the poles out etc.

All the parts laid out before start.

That winding

Not got any more photos from the build..

Also have a 1:1 and 1:4 balun so will make those up too.

Had to add some M6 screw and nut hardware on the 4:1 as the ones I had failed. My mistake tightened the bolt too much.
