Is the length of a mobile antenna the only factor that determines its tuning?
Can there be anything else added to the internals of the antenna that aids its tuning?
For example, I have a Mitex radio and it's antenna is tuned to 400-470 mhz. Going by this logic, my SDS100 antenna is the same length, so would it perform in the same way to a tuned antenna in that part of the radio spectrum?
If so, why is the length important?
