President Maryland 5/8 Wave 500-Watt CB Antenna

When you want maximum reach out of a mobile CB, the President Maryland delivers. This 58-inch, 5/8-wave radial whip is built around an AC4 stainless steel element and a bottom-loaded coil, so it launches more of your signal toward the horizon than a typical short fiberglass stick. A set of tuning rings at the base lets you dial in a low SWR by hand — no cutting, no guesswork — while the heavy-duty build shrugs off weather and highway miles. Rated to 500 watts PEP with a universal 3/8" x 24 base, it's an ideal upgrade for truckers, overlanders, and off-roaders who spend real time on channel and want to be heard.

*Please note: All items that are more than 4 feet in length are charged a $9.95 oversized item shipping fee.

President Electronics is a long-established name in CB radio, and the Maryland is its flagship radial-whip mobile antenna. The 5/8-wave design and base-loaded coil give it an efficiency edge over shorter center-loaded fiberglass antennas, which translates to stronger transmit and clearer receive at distance. The AC4 stainless steel whip resists corrosion and stands up to weather, car washes, and trail branches, while the base tuning rings make SWR adjustment quick — slide them to lock in your lowest reading without ever trimming the whip.

If you're comparing it to a classic center-loaded trucker stick like the Wilson 2000, the Maryland trades the trucker coil for a taller 5/8-wave whip that many drivers find easy to tune and just as strong on the highway.
