Description
When the Network Fails, the Air Does Not. Every communications plan that depends on a tower has a single point of failure, and that point is somebody else's decision. The Long Wire is a citizen band radio module covering 25.615 to 30.105 MHz at 8 watts, built in the ultra-mini CB-40M form factor: a transceiver small enough to live inside a vehicle, a go-bag or a bench build, and loud enough to be heard well past the edge of mobile coverage.
The specification matters more than the marketing here. Forty channels across the citizen band with an 8-watt output is a genuine working radio, not a toy walkie-talkie, and 25.615 to 30.105 MHz covers the CB band plus the neighbouring segments used in different regions. The ultra-mini chassis is the design decision that makes the product useful: a radio that fits behind a dashboard or inside a portable case gets installed, whereas a full-size set gets discussed and then forgotten. Combined with the compact antenna supplied in the bundled configurations, it is a complete station rather than a component waiting for a project.
The people who buy this are not buying a gadget. They are buying a second channel of communication that does not require permission from an infrastructure owner: overlanders on remote tracks, farm and site operators coordinating across open ground, event crews, and households that want a radio in the house that works when the fibre does not. Screen colour and antenna bundle are the only variables, and both are decided by where the radio is going rather than by what it looks like.
Range is not a feature of the radio. It is a feature of what you can still reach when everything else stops.
Key Features
- ✦ 8 W output. Real transmit power in the CB class, not the sub-watt figure typical of handheld consumer radios.
- ✦ 25.615 to 30.105 MHz coverage. The citizen band plus adjacent segments, usable across regions with different channel plans.
- ✦ CB-40M ultra-mini chassis. Compact enough for a dashboard recess, a console build or a portable case, which is the difference between installed and abandoned.
- ✦ Antenna-bundled configurations. Order as a bare module or with a compact antenna included, in orange or blue.
- ✦ Two screen colours. Blue or orange backlighting, selected for night visibility in a vehicle rather than for aesthetics.
- ✦ Five fulfilment origins. United States, Spain, Poland, Russian Federation and China, so lead time can be matched to the region.
- ✦ Infrastructure-independent. No subscription, no account, no coverage map: the link exists as long as the two radios do.

Where It Belongs
Overlanding and remote travel is the primary use: a convoy link that survives beyond the last cell tower and does not depend on a satellite subscription. Farm, ranch and construction sites use CB because the alternative is shouting across open ground, and a fixed module inside a machine or a site hut is more useful than a handheld that goes missing. Event and security crews take it for short-range coordination without channel licensing overhead. The domestic case is the quiet one and perhaps the most sensible: a compact radio in a kitchen drawer is the difference between knowing what is happening during a regional outage and simply waiting it out.
Questions, Answered
Q: Does this need a licence?
A: Citizen band operation is licence-free in most jurisdictions, but the rules differ by country and the 25.615 to 30.105 MHz span crosses segments that are not universally allocated. Check your local regulations for the channel plan you intend to transmit on.
Q: What does 8 W actually buy me?
A: A meaningful step up from low-power handhelds, particularly with a decent antenna and a clear line of sight. Terrain and antenna height still matter far more than the wattage figure.
Q: Should I order the version with the antenna?
A: If you do not already have a matched CB antenna, order the bundled configuration. Running a transceiver without a suitable antenna is the most common way these modules are damaged.
Q: Blue or orange screen?
A: Blue backlighting is easier to read in daylight and works well in a bright cab. Orange preserves night vision better for dark-cab and night-driving use.
Q: How quickly can it reach me in Europe?
A: Spain and Poland are available as fulfilment origins alongside the United States, Russian Federation and China. European buyers should select a European origin to avoid import handling.
Q: Is it a complete radio or just a board?
A: It is a finished ultra-mini transceiver module with a display and controls, sold either bare or bundled with an antenna. It is not a bare circuit board and it is not a handheld.
