[UK-CONTEST] Antenna for SSB field day

[Callum MØMCX]

Yes. The 40m legs are resonant on 7 mhz and 22 mhz however the K3  
tuner handled the slight mismatch on 15m.

I designed it for rapid deployment using caribinas and paracord at  
around 10m to feedpoint. Terry was very happy with it and had it up in  
a few minutes at 5B4. Coax was 7mm Aircell, very light but similar  
characteristics to 213.

It was a fun project and took a weekend to iron out all the bugs. 80m  
was not factored in but additional legs could easily be manufactured.  
It rolls up to the size of a toilet roll.
