[TowerTalk] reversible Beverage

[RT Clay]

I used to have a DX Engineering reversible beverage here and did make my own homebrew open wire also because of the cost. I used aluminum electric fence wire. I did use a narrower spacing to try and stay closer to the ~400 ohms of ladder line (its actually lower than 450 ohms). I think my spacing was around 1.5-2 inches. It worked fine.
