The  Barrett 914 range of manual tapped whip antennas are designed for
land  mobile  installations  where a limited number of frequencies are
required.

Frequency  selection  is achieved by the re-location of a tapping plug
to  a  specific socket for each frequency. Barrett 914 antennas have a
maximum of 12 individual frequencies in the range 2 to 30MHz.

The  complete  assembly  consists  of  a helically wound whip section,
encapsulated  in  a tough polyurethane resin and a separate heavy duty
mounting  base  and  spring.  Connection  to the transceiver is via an
integral UHF coaxial connector in the mounting base.
