Can a CB antenna be trimmed/tuned to work for GMRS? I have a Wilson Little Wil magmount base. The antenna is a stainless steel rod.
Trusting the internet I converted 465.000 MHz to wavelength of 25.38248 inches. I cut the CB antenna whip off at about 27". Then started cutting little pieces off and checking with a surecom swr meter. I never got a reading under about 2.5. My antenna length is now about 20". And the swr reading is 2.9 to 3.0.
Obviously I started my experiment with very little knowledge. Do you have any suggestions / corrections or where to go to learn?
