Toot

I want to run some wire antennas between two trees. If I put a steel I-hook on each tree 20-25 ft up, how do I simultaneously keep the EFHW antennas from drooping and allow for the trees to sway independently in the wind and not snap the wires? #hamradio #amateurradio #antennas

@profoundlynerdy

Hang a weight over one side so there's always 20kg of pull on the wire, long or short?

@RoyBrander @profoundlynerdy Would ARRL have something on that specific issue? Maybe page 264 onward, sag calculations.
