| 131.8 | pylon antenna | 25421::FALKOF | Fri Feb 14 1997 16:01 | 16 | |
I was reading in a 25 year old antenna book (from 73 mag) about an
antenna often used (then?) in commercial applications. Something about a
"mumble pylon" antenna. It is like a cylinder with a vertical split
along a seam, and two inward folding plates whose distance apart formed
a capacitor. Supposed to have some gain also.
Although it may have a greater diameter than a small pipe, it looks
like it couldn't be more simple than rolling a sheet of aluminum or
copper sheeting and soldering at the right place. Then use a cable wrap
tie to adjust the spacing of the cylinder gap and thus the plate distance.
Does anyone have any further info/details/notes?
