Well, after three years up 50' in a maple tree my centre support line for my 80m OCF Dipole finally broke. The antenna is still up the tree, either the balun or the coax has found a branch to hang on to, but I could pull it all the way down using the coax.
Oh well, I can't complain after having to do little to no maintenance to it over the past 3 years. I'll have to get one of the guys to shoot a new line over the same tree with their compressed air cannon and I'll be back in action in no time.
The plan is to replace the current rope with UV resistant and to also use a piece of aircraft cable attached to the balun for extra strength.
The fun of amateur radio!!
