BEAM ANTENNA DESIGN
Posted: Tue Feb 28, 2006 4:36 am
For all you antenna home brewers out there.
I am going to build the 2-meter beam described on page 8-38 of the VHF/UHF DX Book.
Element lengths are given for Free Space, Full Contact with a metal Boom and thru the metal Boom but insulated from the Boom.
Question:
Does Free Space mean for use with a non-metalic Boom such as wood or fiberglass?
Second question:
The element diameter is specified as 4mm (0.157"). I assume I can use 3/16" (0.185") diameter aluminum with no change to the element length? But, you know what ASS U ME can do. Hi...
Tnx, Jerry - W8UJX
