ANTENNA INSTALLATION
TOP COVER POSITION
The antenna must be installed in accordance with good engineering
practices for best results. See Figures 14 and 15.
Mount the antenna in the 3/8 inch hole provided in the top of the
weatherproof case according to the antenna manufacturer's instructions
with the following exceptions:
1. Discard the lockwasher provided with the antenna and use the thin
lockwasher provided.
2. The 1/2-inch braided ground strap is required for 29-50 MHz operation
and is recommended for all other bands.
3. For 29-50 MHz, 136-174 MHz, and 450-512 MHz antennas, use the
antenna whip cutting chart provided in this manual (see Table of
Contents). Do not use the cutting chart supplied by the antenna
manufacturer.
When cutting the antenna cable, be sure to have enough slack so that the
case can be opened without straining the antenna cable connections. Route
the antenna cable to the radio along the opposite side of the radio from the
antenna jack and radio heatsink as shown in Figures 2 and 5.
REAR MOUNT OPTION
Mount the antenna on the rear antenna support 19D904965P1 (See Figure
16). Mount the support to the weatherproof case mounting plate using four
1/4-20 x 3/4" cap screws and 1/4-20 locknuts provided. Cover the hole in
the top of the weatherproof case with the plug provided and seal with RTV
compound, if required.
Connect the sleeved, braided ground strap from the rear antenna support to
the motorcycle chassis.
Slip the supplied grommet over the antenna cable and route the antenna
cable through the cable entrance cover plate on the weatherproof box to the
radio.
Connect the ground strap from the rear support bracket to the motorcycle.

8.
Remove the wire metal handle (if present) from the 13.2 Mhz plug-in
reference oscillator located on the synthesizer board.
9.
The logic board in the top of the RANGR radio contains one or two
plug-in crystals. One of these is located under the removable metal
shield. Put a drop of RTV on each end of the crystal to stake the
crystal to the printed board.

10. Set the transmitter power to 25 watts (except 30 watts on low band).
The power adjust pot is accessed through a hole in the logic board
adjacent to the synthesizer module.
11. Assemble new RANGR radio top cover 188D5003P1 and torque
screws to 21 inch-pounds.
12 Apply label in vacant recess on the RANGR rear casting.
CABLE INSTALLATION
Cable installation consists of making the power connections, and then
running the radio power/control and vehicle system cables to the control
unit.
To assure the feasibility of the cable routing, it is suggested that the
cables be run before installing the two-way radio. Try to route cables
away from exhaust pipes, mufflers, and moving parts, or where mechanical
