Whatever you use for wire, it needs to float at the supports. Anchor it at only one end and tension it tightly at the other end.
I use my own ladder line, made from .061" diameter plated steel electric fence wire and spacers made from 1/4" dia. plastic coat hangers. Supports are 10' high and 100' apart. It's taken a lot of abuse, including large tree branches falling on it and a porch roof hurled against it by a small tornado. Some supports broke during the flying porch roof incident, but the wires never broke either time. WD-1A military telephone wire works well, if you have the right impedance matching transformers. Having said all this, I know that a lot of Topbanders use that brown plastic window line for their Beverage antennas. Which kind lasts? 73, Mike http://www.w0btu.com/Beverage_antennas.html _________________ Topband Reflector
