NSTALLATION
The supplied antenna provides good results over the entire frequency range of the trans-
ceiver. However, for enhanced base station medium-wave and shortwave reception, you
may wish to connect an external (outside) antenna.
The supplied antenna consists of two sections: the “Base Antenna” (used for operation
above 50 MHz), and the “Extender Element” (used for monitoring of frequencies below 50
MHz).
To install the supplied antenna
Hold the bottom end of the antenna, then screw it onto the mat-
ing connector on the transceiver until it is snug. Do not over-
tighten by use of extreme force.
When operating the
VX-7R
on the 50 MHz band and lower
frequencies, disconnect the antenna cap from the base antenna,
then screw the Extender Element onto the Antenna Base. Of
course, the
VX-7R
may be operated on frequencies higher than
the 50 MHz band while the Extender Element is still attached
onto the Antenna Base.
Notes:
¦
Never transmit without having an antenna connected.
¦
When installing the supplied antenna, never hold the upper
part of the antenna while screwing it onto the mating con-
nector on the transceiver.
¦
If using an external antenna for transmission, ensure that
the SWR presented to the transceiver is 1.5:1 or lower.
¦
Take care not lose the antenna cap when removing it from
the Base Antenna.
