[UK-CONTEST] More about DX loops

[Callum]

Thanks to Alan and John who both mentioned similar aspects of loops for DX -
also to Adrian who brought the topic up.. 

In my mind, I have a loop for 80 meters, slung off the 100 foot trailer
tower at a club field day event. I was going to use a 4:1 balun, however
perhaps I could get away with a few turns of coax? 4:1 might be too steep.

My dilemma is that if I feed this 1/4 wave down one of the legs, the weight
of the balun / coax / feedline etc will pull the delta loop into an odd
shape. 1/4 wave "down" is just about a third up from the bottom (I'll work
it out - this is just for example!) - I wonder the best way of supporting
this, or perhaps I use a heavier gauge wire than I normally do and just pull
it tight to take the "bend" out? I don't want to snap the balun etc. I built
a 40 meter vertical delta loop for CQWW last year and fed it like this, but
I supported the weight by managing to take the coax off at 90 degrees to an
upstairs room so there wasn't mush real weight on the thing.

Any ideas on the engineering side, how I might do this as it's really
nagging me?

Callum.
