homemade external/internal antenna for handheld.

("RST Engineering" wrote)
1. With a standard handheld, what would the average length be (approx)
for the rod(s)?

It is a function of rod diameter. With an infinitely small diameter wire,
the length for each rod would be about 23.2" for a geometric (*) band
center of 127 MHz. With a half-inch diameter rod, that would reduce to
20.2 and in between is in between. (*) The geometric center of the band
is the square root of the (bottom end of the band times the top end of the
band).


Thanks for the answers.

I wonder if I could take a SO-239 to BNC male adapter, solder the coat hanger rod into the SA-239 and use the setup instead of the rubber ducky antenna on my Icom A23. Will it work?

Thanks a bunch,

Victor

works well for me. It consists of 4 parts: a length of RG-58 coax
cable, one SO-239 coax connector, one PL-259 coax connector and one coat
hanger. The coax and connectors are available from your local Radio
Shack and you can raid the hall closet for the hanger!
