First you get a 53’ wire, then cut the string to the same length. :-) When I was cutting wires for SOTA use, I attached one end to something that wouldn’t move, hooked the end of my 25’ tape measure to the same spot, then stretched them both out. I marked the 25’ point on the wire, then repeated the procedure.
For HF, exact dimensions rarely work. Anything close to the wire, like trees or houses, will electrically shorten the wire thanks to the capacitance. So a wire can be different electrical lengths with leaves on and off a tree. wunder K6WRU Walter Underwood CM87wj http://observer.wunderwood.org/ (my blog) > On Feb 9, 2016, at 1:12 PM, Lynn W.
