This is an experimental antenna project- feedback appreciated!
Here's a very simple antenna to build which only
requires two supports and is easy to install. The only cost is some wire
and rope plus PVC scrap for the insulators!
A two element Yagi
will have a gain of about 3 to 4 dBd and have a driven element with either
a reflector or a director. The reflector is about 5% longer than the
driven element with the driven element nearest the receiving station
or use the driven element with a director that is about 5% shorter than
the driven element with the director nearest the receiving
station. Either way you use it, it should provide substantial
gain over a standard dipole!
Driven Element---- 8 feet and 10 1/4 inches per side (17'-8 1/2" total)
Reflector---- 18 feet 9 1/4 inches total length
Spacing----7 feet 2 inches
Some experimenting and a tuner will be required. I have not tried this design yet.
The dimensions should be good starting points. You can add a Director (16'-8" long and use same spacing of 7'-2") for a 3 element version to get about 5 -7 dBd gain!
Not bad for some wire, a few pieces of PVC and a little fun in experimenting!
Any and all feedback is appreciated.
