About Whip Antenna Frequencies:
Frequencies for whip antennas are specified by the
block number. For example, AMM-25 is the straight
whip model cut to the block 25 frequency.
L-Series transmitters and receivers tune across a
range covering three blocks. The correct antenna for
each of these tuning ranges is the block in the middle
of the tuning range.
