Unfortunately, a too-long vertical tends to send the radiation
up at a high angle. EZNEC sez a 6' vertical used on 151 MHz
will have a take-off-angle of about 38 degrees - not good for
vhf mobile.
RS makes a fiberglass CB whip. How about cutting one of those
to your desired length and drilling through the center conductor
at the proper 1/4WL point? Epoxy the hole? Paint the fiberglass
to make it look like metal?
Hi Bruno,
This is your best solution both for a correct length antenna and a
cosmetic appearance.
