Will it work with my CB radio?

Yes, it covers the 26-30 MHz CB band and handles up to 100 watts PEP, so it suits standard 4-watt CB radios and many 10-meter transceivers.

Do I need to drill holes to install it?

No. The base is a magnet, so it sits on a flat metal surface such as a roof or trunk lid. Clean the surface first and route the coax through a door or window gap.

How long is the cable?

The braided coaxial cable runs about 15 feet 9 inches, which reaches most cabs, trunks and small boat cabins.

Is it good for marine use?

It is built for outdoor use with a stainless whip and chrome hardware, but the magnet needs a steel surface. On fiberglass boats you will need a metal ground plane under the mount.

How does it compare with a fixed NMO mount?

A fixed NMO mount gives a more stable ground plane and usually better range. This magnetic antenna trades some performance for portability and no drilling.

The antenna with its magnetic base and the attached heavy-duty braided coax cable. A radio is not included.

What reviewers say

Buyers of magnetic CB antennas in this class generally report easy setup and acceptable range for local use, while noting that magnet mounts need a good ground plane and periodic SWR checks. Reception and transmit quality are described as fine for a compact whip, not a long-range setup.
