Matt, with shortwave, isn't there some weird formula to determine the length of the wire you need to run? I remember once for fun a buddy and I took his shortwave radio and made a clip on system for his antenna jack. Then we went to a water filtration plant that had a fence around the perimeter with barbed wire around the top and clipped the antenna to a wire that had to run close to a mile with no breaks in it. Just because we could!!!
