Apart from the challenge of making reliable connections to aluminium, are there other "issues" that come to mind in using such wire for antennas? Hi Owen, I've used ordinary house wiring for long-wires and they have survived 100# limb falls that ripped out my matching box from its post. The survival was with the wire, not the box. [warning to Reggie, the prose that follows contains literary allusions] What price tensile strength? The worst thing you can do is pull a wire tight in an attempt to totally eliminate sag. The inverse sine angle of its depression magnifies the stress by huge amounts. A slight sag will never yield a tensile failure in the most pedestrian of wire. 73's Richard Clark, KB7QHC |
