Hey,
I've got a halfwavelengh dipole hanging on the facade of my balcony, it's two 5 meters wires connected through a 1:1 balun to work in the 20m band. I tried to optimise the length by cutting wire to go to the minimum SWR measured on the nanovna, but to my surprised I ended up with only 4,25m wires, far from the theoretical 5m.
I'm just a newbie so I might have done something wrong but I don-t know what, can anybody give me a hint??
Thanks in advance!!!
