INSTAllATION
Location
Prior to begining operation of the transceiver, a basic installation must be done.
Installation of the transceiver itself is a rather simple procedure.
In selecting the location for the unit, two factors must be considered:
~v
1. Access to a ~ AC, 60Hz power source for your BASE STATION installation.
Be sure to connect the AC power cord to an AC power source, not to a DC power
source.
2. The location must be convenient for running the antenna lead-in cable to your
transceiver.
BASE STATION ANTENNA
Since th'e maximum allowable power output of the transmitter is limited by the
F.C.C., the antenna is the most important factor affecting transmission distance.
Only a properly matched antenna system will allow maximum power transfer from
the 52 Ohm transmission line to the radiating element.
The recommended method of antenna tuning is to use an in-line watt-meter or VS-
WR bridge to adjust the antenna for minimum reflected power on channel 19.
The radio may be used with any type of 52 Ohm base station antenna. A ground
plane vertical antenna will provide the most uniform horizontal coverage. This type
of antenna is best suited for communication with a mobile unit. For point-to-point
operation where both stations are fixed, a directional beam will usually increase
communicating range since this type of antenna concentrates transmitted energy in
one di-rection. The beam antenna also allows the receiver to "listen" in only one
direction thus reducing interfering signals.
Antenna height is an important factor when maximum range is desired. Keep the
antenna clear of surrounding structures or foliage. F.C.C. regulations limit antenna
height to 20 feet above an existing structure.
MOBILE OPERATION/EMERGENCY POWER OPERATION
It is possible to operate the WASHINGTON from an external 13.8V DC power
supply for emergency power conditions or from an automobile battery for mobile
operation. The WASHINGTON is supplied with a polarized plug for operation with
an external DC su pply .
Negative lead is black.
Positive lead is red and has the in-line fuse holder as an integral part of the
positive lead.
