Have been looking around for plans for a 1/2 or 5/8 2 meter mobile
antenna to play with. I have several Iron Horse whips I no longer use
and thought id use them as a starting point for a 5/8 2 meter mobile
whip I could use on my CB mount for most of the time. (I use the CB only
when our RV club travels as a group).


I did a ton of google/bing searches but have come up fairly empty. I
know I could buy one cheap but thats not what ham radio is about .

It has been many years, but I recall some CB antennas that were
outwardly similar to a 5/8 wave Two Meter antenna. They consisted of a
base loading coil connected to the vertical whip. The Two Meter antenna
had a grounded coil with whip at the top, with a connection from the
connector's center conductor to a tap on the coil.

The CB whip may have been a little shorter than 5/8 wave on Two Meters,
but it might still be possible to rework the CB coil to match it.
