In this video I will walk though how to build a 30 ft / 9 m antenna support for yourself using simple lumberyard lumber and hardware. I will also show you the modifications I made for my own version that I used at Moose Lake.
Not everyone has a place to support one or both ends of a wire antenna.
This problem is not foreign to the amateur radio operator. Back in the long past, they devised a way of creating their own 30 foot or 9 meter support using basic stuff from the lumberyard. It was 40 foot (12 meter) back then when they could get 22 foot lumber!
I found this design in a 1940 American Radio Relay League (A.R.R.L.) "The Radio Amateur's Handbook." It is what I used as a starting place to create the antenna mast I used in Moose Lake, Manitoba, Canada when I lived there back in the 1990s.
I made some modifications for my own application and it worked great.
