CB Antenna - MS145 CN
The MS145 CN is a professional-grade Citizens Band antenna designed for reliable two-way radio communication in mobile and base station applications. This omnidirectional antenna is widely used by professional truck drivers, emergency responders, and radio enthusiasts who require consistent signal transmission and reception across extended distances. The MS145 CN solves critical communication challenges by providing superior gain, low-angle radiation patterns, and excellent impedance matching for crystal-clear audio quality in CB radio systems operating on the 26-27 MHz frequency band.
Product Overview
The MS145 CN operates as a quarter-wave vertical antenna with a sophisticated radiator design that maximizes electromagnetic radiation efficiency in the CB frequency spectrum. The antenna utilizes a helical coil loading technique to reduce physical length while maintaining optimal electrical performance, making it ideal for vehicle-mounted installations where space is limited. Its construction incorporates a fiberglass-reinforced radome that protects the internal elements from weather exposure, UV degradation, and mechanical stress, ensuring long-term durability in harsh environmental conditions.
This model stands out through its engineered ground plane interaction, which produces a low takeoff angle radiation pattern approximately 15-20 degrees from the horizon. This characteristic is particularly advantageous for long-distance skip propagation and ground-wave communication, delivering superior performance compared to standard monopole designs. The MS145 CN features a 50-ohm impedance match with a VSWR of less than 1.5:1 across the entire CB band, ensuring efficient power transfer from your transceiver and minimal signal reflection losses.

How to Use
Installation of the MS145 CN requires proper mounting on a vehicle roof or fixed base structure with adequate ground plane clearance. Position the antenna at least 12 inches away from other metallic structures, electrical lines, and communication equipment to prevent impedance detuning and signal degradation. Mount the antenna vertically using the supplied hardware, ensuring all connections are tight and weatherproofed with appropriate sealants. Connect the antenna feed line to your CB radio transceiver using quality 50-ohm coaxial cable, keeping cable runs as short as possible to minimize insertion loss.
Once installed, perform a VSWR check using a CB radio SWR meter to verify proper tuning. Adjust the antenna position or ground plane configuration if VSWR exceeds 1.5:1. For vehicle installations, ensure the coaxial cable is routed through the interior with proper grommets and strain relief to prevent water ingress and mechanical damage. Test communication at various distances and directions to confirm omnidirectional coverage and optimal signal quality before full operational deployment.
Frequently Asked Questions
What is the optimal ground plane size for the MS145 CN antenna?
The MS145 CN performs best with a ground plane of at least 4x4 feet for fixed installations or a full vehicle roof for mobile applications. Larger ground planes improve radiation efficiency and lower the radiation angle. For vehicle mounting, the entire roof acts as the ground plane, providing excellent performance. Minimum ground plane should not be less than 24 inches in any direction to maintain VSWR below 1.5:1.
Can the MS145 CN be used with amplified CB radios?
Yes, the MS145 CN is fully compatible with amplified CB radio systems. However, ensure your coaxial cable is rated for the increased power levels, typically using RG-8 or equivalent low-loss cable for amplified setups. The antenna itself can handle continuous power output up to 12 watts without degradation. For higher power applications, verify your local regulations regarding CB radio power limits in your region.
How does the MS145 CN compare to standard CB antennas?
The MS145 CN offers superior performance through its engineered low-angle radiation pattern, which provides better long-distance communication compared to standard vertical monopoles. The helical coil loading maintains full electrical efficiency while reducing physical height, making it ideal for vehicle installations. Its VSWR stability across the entire CB band ensures consistent performance across all 40 channels without retuning.
What cable and connectors do I need for installation?
Use 50-ohm coaxial cable such as RG-58 for short runs under 25 feet or RG-8 for longer installations to minimize signal loss. The antenna typically features a PL-259 connector, so ensure your CB radio has a compatible SO-239 connector or use an appropriate adapter. Always use quality connectors with proper weatherproofing to prevent corrosion and signal degradation.
