ANTENNAS

Antennas For Peterbilt Trucks

Reliable communication and navigation start with the right antenna. Whether you're running CB radio, satellite, GPS, or cellular-based fleet tracking systems, a properly matched antenna keeps drivers connected and dispatchers informed. We carry replacement and upgrade antennas compatible with Peterbilt trucks, including magnetic-mount, roof-mount, and mirror-mount styles suited for long-haul and regional applications.

Frequently asked questions about antennas

What type of antenna do I need for a CB radio on a Peterbilt?

Most Peterbilt drivers use a 102-inch steel whip or a co-phase dual antenna setup mounted on the mirrors or roof. The co-phase setup is popular for long-haul drivers because it provides better signal propagation front to back. Make sure your antenna is tuned to a low SWR (ideally 1.5:1 or lower) to protect your CB radio and maximize range.

Can I use the same antenna mount for both CB and GPS?

Generally no — CB antennas and GPS antennas use different frequency ranges and connector types. GPS antennas are typically low-profile, adhesive or magnetic-mount units that connect to a fleet telematics module or in-cab navigation unit. Running them on separate mounts ensures each antenna performs optimally without interference.

How do I know if my truck's antenna or cable is causing poor signal?

Start by checking the coax cable for damage, corrosion at the connector, or kinks near the mount. A bad ground is one of the most common causes of poor CB performance — the antenna mount must have a solid metal-to-metal connection to the cab. If the cable and ground check out, use an SWR meter to test the antenna itself before replacing it.
