I need to replace my 20m antenna, which is a end fed 1/4 wave wire on my apartment balcony, made of speaker wire (the antenna, not the balcony), it's 22 AWG, just the basic stranded wire with clear jacket that you use to hook up stereo speakers. Before I do that, I'm wondering if I should go buy something heavier, 18 AWG or maybe even bigger? My thinking is bigger wire may give better performance. I have lots of the speaker wire around, but if it'd make a difference, I may go get something thicker. thanks for any suggestion on this..
