ANTENNA GUIDE
This guide is intended to provide information and instructions
regarding antenna installation and antenna tuning.
PLASTIC WASHER
METAL ROOF
• 3/8” Hole
• Scrape away paint
on UNDERSIDE to
provide metal-to-metal
contact
INSTALLATION
• F or best performance, mount the antenna on a metal or
aluminium roof in the center. The ½ wave NGP (No Ground
Plane) antennas do not require a ground plane (meaning,
metal surface) but it is always best to have enough metal
surface area over 2’x 2’ area.
•M
ount NMO connector to a 3/8” hole in roof or roll bar
top. Be sure to scrape away any paint on the underside so
the NMO mount gets a good metal contact. Route the coax
cable away from ignition boxes, coils, HID ballasts, amps,
headset cables, and other components that carry power or
emit RF interference.
• I MPORTANT! If there is any excess coax cable after
installation DO NOT COIL THE CABLE! Coiling coax cable
will cause transmit problems and limit radio range. Ideally,
the coax should be cut to exact length and re-crimped with
connectors. However, if that option is not available, route
the cable further around the car. We have a video online
that offers detailed information about cutting coax, proper
antenna installation and tuning. Visit our YouTube page
(youtube.com/ruggedradios) and search for “Rugged Radios
Mobile Radio Antenna Tuning, Trimming, and Connector
Installation.”

ANTENNA GUIDE
This guide is intended to provide information and instructions
regarding antenna installation and antenna tuning.
ANTENNA TUNING
ost antennas are already pre-tuned (cut to length) to perform at a specified frequency range. If the length of your antenna
M
does not match the frequency range you need as shown below, then modifications may be required. Refer to the charts
below for your antenna type and proper cut length.
