INSTALLATION
■ Antenna installation
Antennas play a very important role in receiver operation.
Connecting a poor quality antenna to the IC-PCR100 will re-
sult in less than optimum performance.
Select antenna(s), such as a well-matched 50
Ω
antenna and
feedline. 1.5:1 of Voltage Standing Wave Ratio (VSWR) is rec-
ommended for a desired band. Of course, the antenna line
should be a coaxial cable.
CAUTION:
Protect your receiver from lightning by
using a lightning arrestor.
NOTE: The supplied antenna is a simple plain antenna which
may not obtain indicated specifications. To obtain maximum
performance from the IC-PCR100, you must purchase an ex-
ternal wide band antenna such as an optional Icom AH-7000
(25–1300 MHz), etc.
Contact your nearest Icom Dealer or Service Center for re-
garding optimum antenna locations.
The antenna connector type is BNC, so an adapter may be
necessary to connect an optional antenna.
■ Grounding
R WARNING: NEVER use a gas pipe or electrical
conduit pipe for grounding.
To prevent accidents involving electricity and interference
from computers, ground the receiver through the GROUND
terminal on the rear panel.
For best results, connect a heavy gauge cable to a water pipe
or long, earth-sunk copper rod. Make the distance between
the [GND] terminal and ground as short as possible.
