CB & Two-Way Radios: what Claude and GPT would buy
Two AI models chose on their own, with no web access. Nobody tested these products: this is what each one says, and how to check it.
They disagree: Claude chooses Cobra and GPT chooses Motorola
In Electronics, Claude and GPT choose the same brand in 21 of 42 categories.
Claude Opus 5.5 · October 27, 2026
Cobra 29 LTD Classic
It is the long-running standard 40-channel mobile CB, with full-size controls, an SWR meter for antenna tuning, and parts and installers that know it everywhere.
Not for: People who only need short-range talk between hikers or family cars, where licence-free FRS handhelds are simpler, and drivers with no dash or under-seat space for a full-size chassis.
GPT 6.1 Sol · November 10, 2026
Motorola Talkabout T800
License-free FRS operation, weather alerts, and smartphone-assisted offline location sharing make it versatile for family outings and outdoor trips.
Not for: Reliable long-distance communication through dense buildings or rugged terrain.
Claude also lists Motorola among the brands that matter.
Which one fits you
compact CB for tight cabs and Jeeps
Uniden PRO520XL
It is a small, simple 40-channel CB that fits where a full-size radio will not.
Not for: Users who want an SWR meter, weather alerts or a large display on the radio itself.
handheld CB that can also go in the vehicle
Midland 75-822
It works as a portable CB and converts to a mobile unit with an adapter, which suits occasional off-road or trail use.
Not for: Anyone expecting full mobile-CB range from the stubby antenna it uses in handheld mode.
GMRS vehicle radio for convoys and repeaters
Midland MicroMobile MXT275
It is a compact GMRS mobile with the radio controls in the handset, a removable external antenna, and much clearer audio than CB for group trail runs.
Not for: People who do not want to get a GMRS licence, and groups whose members already use CB.

Brands that matter
- Cobra: Mainstream CB maker with full-size and compact mobiles and the long-running 29 series.
- Uniden: Well-known CB line from compact to SSB-capable models; also makes scanners.
- Midland: Strong in GMRS (MicroMobile mobiles and handhelds) and also makes CB radios.
- Motorola Solutions: Talkabout consumer FRS line; the business radios are a separate, pricier world.
- Galaxy: Known for SSB-capable CB base and mobile radios used by enthusiasts.
What to avoid
- Choosing a radio on 'miles of range' claims, which assume ideal line of sight and are rarely achieved on the ground.
- Using uncertified multi-band handhelds to transmit on FRS or GMRS; it is not legal even though they will tune the frequencies.
- Installing a CB without checking SWR, or using a short magnet-mount antenna on a vehicle with a poor ground plane.
- CB 'export' or modified radios sold with extra power or extra bands, which are not legal for CB use.
Questions
Should I get CB or GMRS for off-roading?
Use whatever your club or convoy uses. GMRS gives clearer FM audio and repeater access but needs a licence; CB needs no licence and is still common with truckers and older off-road groups.
Will a more expensive radio give me more range?
Mostly no. Within a service, legal power limits are fixed, so antenna height, antenna quality and terrain decide range far more than the radio does.
