TWAYRDIO 13in Magnet Mount CB Antenna 26-28MHz - Compact Mobile Signal

In this review the TWAYRDIO 13in magnet mount CB antenna is evaluated for drivers and hobbyists who need a compact, easy to fit antenna for 26-28MHz CB radios. The single biggest reason to consider it is its combination of a short 13in whip and a strong magnetic base with 13ft RG58 coax and PL259 connector, which makes mobile installation straightforward while still delivering a usable 3dBi signal and a low VSWR for efficient transmission.

Key Features

• Frequency range: Covers 26-28MHz (10-11 meters), making it compatible with the common CB band for reliable voice communication.
• Compact size: The 13in antenna body keeps the overall profile low so it can be mounted on vehicles where a full-length antenna would be impractical.
• Magnet mount: The 2.7in magnet base provides quick, non-permanent mounting and helps place the antenna where reception and clearance are best.
• Ready cabling: Includes a 13ft RG58 coaxial cable terminated with a PL259 connector for plug-and-play connection to most mobile CB radios.
• Power handling and performance: Rated to 50W max with a VSWR <= 1.5 and about 3dBi gain, which balances compactness with acceptable transmit/receive efficiency.
• Durable build: Constructed from a simple antenna body, magnet mount and coax designed to be lightweight and withstand routine mobile use.

Who It's For

The TWAYRDIO 13in magnet mount antenna suits truckers, RV owners, and casual CB users who need a small, unobtrusive mobile antenna that still works across the 26-28MHz CB band. Its 13ft coax and PL259 termination make it particularly convenient for people who use mid-market CB radios from brands like Cobra, Uniden and Midland.

It is not aimed at users who require maximum range or heavy-duty base stations; those wanting long-range performance or a fixed rooftop installation should consider a full-length or professionally mounted antenna system instead.

Pros & Cons

Pros

• Compact 13in size that fits many vehicles without major clearance issues.
• Included 13ft RG58 cable and PL259 connector enable fast installation and compatibility with common CB radios.
• Low VSWR (<= 1.5) and 3dBi gain provide efficient RF transfer for its form factor.
• Magnet mount allows temporary placement and easy repositioning to improve reception.

Cons

• Short whip and magnet mount limit ultimate range compared with full-size or professionally mounted antennas.
• Magnet mount requires careful securing on rough roads to avoid shifting; not a substitute for permanent mounts in severe conditions.
