DX or local contacts. It now features stainless steel hardware for all electrical and
most mechanical connections.
The antenna is self-supporting and can survive winds in excess of 80 mph. It is
highly portable and knocks down to an overall length of 5 feet.
WARNING
When installing your system, take extreme care to avoid
any accidental contact with power lines or overhead }

shown in Figures 2, 5 and 7. After attaching the coax, seal it from moisture using
Coax-Seal® or some similar substance.
