Frequently Asked Questions About Best Low Profile CB Antenna

Do low profile antennas significantly reduce my CB radio range?

Yes, they do, compared to a full-sized quarter-wave whip (which is about 102 inches tall). Range reduction is inevitable because performance in CB radio is directly tied to the physical length of the antenna. However, the best low profile cb antenna models (like the 18-inch options) use specialized loading coils to electronically lengthen the antenna, providing a good middle ground. You may lose miles of range, but you retain essential truck-to-truck communication and local broadcasting.

How important is SWR tuning for these smaller antennas?

SWR (Standing Wave Ratio) tuning is extremely important, perhaps even more so with low-profile antennas. Because these antennas are inherently compromised in length, improper tuning can quickly turn a mediocre signal into a useless one, and it can potentially damage your radio transmitter. We highly recommend using an SWR meter, though models like the pre-tuned Uniden reduce this necessity greatly.

Can I install a magnetic mount low profile antenna on a fiberglass RV?

No, traditional magnetic mount antennas require a ferrous metal ground plane (like a vehicle roof or hood) to function correctly. Fiberglass, aluminum, or composite materials will not provide the necessary ground plane. For RVs or vehicles without a metal roof, you must use a drilled mount system that is explicitly designed to create an artificial ground plane or use a mirror mount.

What is the ideal location for mounting a low profile CB antenna?

The most ideal location is the center of the largest metal surface on your vehicle, typically the center of the roof. This provides the most efficient and symmetrical ground plane, leading to the best radiation pattern and maximum range. If mounting on the roof isn’t possible, the center of the trunk or the hood are acceptable secondary locations for a magnetic best low profile cb antenna.

Are the Midland GMRS antennas compatible with standard CB radio frequencies?

No. The Midland MXTA25 and similar “Ghost” style antennas are specifically designed for the GMRS frequency band (around 462 MHz). Standard CB radio operates on 27 MHz. You cannot use a GMRS antenna for CB, nor can you use a CB antenna for GMRS, as they are tuned to drastically different wavelengths.

What wattage rating should I look for in a low profile CB antenna?

For a standard mobile CB radio (which legally transmits at a maximum of 4 watts), an antenna rated for 30 watts is sufficient, such as the Bingfu model. However, if you plan to use an older radio, or a single-sideband (SSB) radio, or ever incorporate an amplifier (where legal), you should choose an antenna rated for 100 watts or more, like the Uniden or President Virginia, to prevent burnout.
