I made a 6 meter antenna from 1/2 inch copper pipe. Center fed(gamma match using 12 inches of 1/4 copper tube), mostly like a letter U with the upper ends folded in towards the center but not connect
I am thinking of dragging a 2 meter collinear vertical up in a tree. I am under CC&Rs like many of us and just cannot make out some of the group on simplex that I like to frequent using the vertical
An 80 lb bag is rated at 1/2 cubic ft. 27 cu ft=yd = 54 bags/per yard. Home depot 2.38 I think for the cheap stuff per bag = 128.54 plus tax and a lot of work. Probably cheaper to have the readymix t
Not being an engineer, will someone tell me why? What are the actual important things about the tower base? My thoughts: 1. must extend below the frost line. 2. weight 3. surface large enough to atta
