For most pickups, buy a 4-foot fiberglass CB antenna on a mirror or stake-pocket mount, or a Wilson T2000 on a solid stud mount, and get at least half of it above the cab. If you can't drill or clamp, the Wilson Little Wil magnet kit on a steel roof is the no-tools choice. Then tune it with an SWR meter before you talk.
The antenna brand matters less than three things you control: where it mounts, how much of it clears the roof, and whether the mount is grounded to the truck.

How we picked
We pulled Amazon's results for "cb antenna for truck," "cb antenna mount" and "cb coax cable" on October 13, 2026. The Wilson T2000 with the 5-inch shaft led with 700 bought in the past month and 2,000+ ratings; the Prostick 2', 3' and 4' fiberglass antennas followed at 400 a month each. We kept antennas from makers that state the frequency range and connector, and checked each listing's claims against the FCC's CB rules.
Then we leaned on what the installer-run sites agree about, especially Right Channel Radios' antenna guide and the tuning guides from Cobra and CB Radio Supply: length, height above the roof, and ground plane decide performance.
"How we pick" means listings and published installation guidance, compared with 47 CFR Part 95 Subpart D. We didn't mount these on our own trucks. How we research.
What makes a CB antenna work on a truck
CB channels sit between 26.965 MHz (channel 1) and 27.405 MHz (channel 40) (47 CFR 95.963). A quarter wavelength at channel 19 is about 108 inches in free space, which is why the classic full-size CB whip is 102 inches: add a spring and mount and you're close to resonant. Anything shorter uses a loading coil to make up the length, and gives up some efficiency doing it. Right Channel Radios' rough guide puts a 3-foot fiberglass antenna at 3 to 4 miles and a 102-inch whip at "at least 10 miles," with terrain and mounting deciding the rest.
Two more things decide whether any antenna works:
- Ground plane. Most CB antennas need the truck's metal as the other half of the antenna. A mount that isn't electrically bonded to the chassis gives high SWR no matter what you screw onto it. Fiberglass bodies, RVs and boats need a no-ground-plane kit.
- Tuning. Every install is different, so every antenna gets tuned with an SWR meter on channels 1 and 40. Our CB antenna tuning guide walks through it.
Ignore the watt ratings
Antenna listings advertise 300, 1,000 or 3,500 watts. A legal CB radio puts out at most 4 watts carrier on AM or FM and 12 watts PEP on SSB (95.967), and using an external RF amplifier on CB is prohibited "under any circumstances" (95.939). A higher watt rating means a heavier coil that survives abuse. It doesn't add range to a legal radio, so don't pay extra for it.
Pick the mount first
| Mount | Good for | Watch out for | Pair with |
|---|---|---|---|
| Mirror mount | Pickups and semis with tube mirror brackets | Ground through the mirror bracket; may need a ground strap | 3- or 4-ft fiberglass, or dual antennas |
| Stake pocket / bed rail | Pickups; uses the steel bed as ground | Low on short-bed trucks; tailgate clearance | 4-ft fiberglass or a trucker antenna |
| Roof magnet | No drilling, moves between vehicles | Needs a steel roof; won't hold on aluminum | Wilson Little Wil, Tram magnet kit |
| Stud (drilled) | Permanent roof or toolbox install | Drilling a hole; seal it | Wilson T2000, 102-in whip on a spring |
| No-ground-plane kit | Fiberglass bodies, RVs, boats | Somewhat less range than a grounded install | NGP-specific antennas |
The best CB antennas for trucks
Wilson T2000 (5-in shaft)
The best-selling CB antenna on Amazon right now, and the classic center-loaded trucker design: a coil in the middle, a 49-inch stainless whip on top, and a standard 3/8 x 24 ferrule that threads onto any common stud mount. Wilson calls it "AM/FM ready" with a large coil housing. The shaft is what you choose; the 5-inch suits most mirror and roof mounts.
- Typecenter-load trucker
- Whip49 in stainless
- Shaft5 in
- Frequency26-30 MHz
- Ferrule3/8 x 24 chromed brass
- Impedance50 ohm
Why it stands out
- 2,000+ ratings and 700 bought last month
- Standard 3/8 x 24 thread fits common mounts
- Steel whip shrugs off branches
Think twice if
- You need it to clear a low garage (it's about 51 inches tall)
- You have no solid, grounded mount for it
Need the coil higher, above a toolbox or bed rail? The T2000 with the 10-inch shaft is the same antenna with a longer base.
Prostick 4' fiberglass
A 4-foot fiberglass stick is the sweet spot for a pickup: long enough to clear the cab from a mirror or stake-pocket mount, light enough not to whip around on washboard roads. Prostick pre-tunes it for the CB band and builds in its VibraSorb anti-breakage base. It's made in the USA, and the 935 ratings say it holds up.
- Length4 ft
- Typepre-tuned fiberglass
- Frequency26-29.5 MHz
- Ferrulenickel-plated brass
- Built-inVibraSorb anti-breakage
Why it stands out
- Good length for most pickups
- Light and quiet at highway speed
- Made in the USA
Think twice if
- You park in a low garage every night (look at the 3')
Shorter clearance? The Prostick 3' gives up some length to fit under garage doors and drive-through canopies.
Wilson Little Wil magnet kit
Wilson's compact magnet kit is the quickest way to put CB on a steel-roofed truck without tools. The heavy 10-ounce magnet holds the 36-inch stainless whip, and the low-loss coil sits in the base. Put it in the middle of the roof and it outperforms many antennas bolted lower on the truck, simply because of where it sits.
- Whip36 in 17-7 PH stainless
- Magnet10 oz
- Coil14-gauge copper
- Impedance50 ohm
- Mountmagnetic, needs steel roof
Why it stands out
- No drilling, roof-center height
- Moves between vehicles
- Wilson coil quality
Think twice if
- Your truck has an aluminum roof (it won't stick)
- You drive through a lot of low branches
Tram 300-watt magnet trucker kit
A complete kit: magnet base, coil, a 35-inch whip and 17 feet of coax with the PL-259 already installed. The rubber boot keeps the magnet from scratching paint. It's the one to buy if you want everything in one box and don't want to source coax separately.
- Whip35 in tapered stainless
- Magnet3.5 in with rubber boot
- Coax17 ft RG58A/U, PL-259 installed
- Frequency26-30 MHz
- Housingone-piece coil and magnet
Why it stands out
- Coax and connector included
- Rubber boot protects paint
Think twice if
- Aluminum roof
- You want lower-loss coax than RG-58
ProComm HSD995-4B dual 4' kit
Two antennas on the mirrors is the trucker look, and it has a real use: when you tow a trailer or have a tall box behind the cab, co-phased antennas fill in directions a single side-mounted antenna leaves weak. Right Channel Radios notes that a single antenna near the center of the vehicle performs best, and duals are usually a poor choice off-road. This kit has everything, including the co-phase harness.
- Antennastwo 4 ft fiberglass, top-loaded 1/4 wave
- Mountstwo 3-way aluminum mirror mounts with SO-239 studs
- Coax9 ft co-phase harness
- Rated750 W
Why it stands out
- Complete kit with mirror mounts and harness
- Helps when towing or with a tall load behind
Think twice if
- You off-road (more to snag, less benefit)
Pro Trucker 102-inch stainless whip
A full-size whip is about as close to a resonant quarter wave as a mobile install gets, with no loading coil in the way. That's why it's the benchmark for range. It's also more than 8 feet of steel that will hit garage doors and trees, so it belongs on a heavy-duty ball mount with a spring, on a truck that lives outdoors.
- Length102 in
- Material17-7 PH tapered stainless
- Fits3/8 x 24 mounts
- StudSWR-adjustable
Why it stands out
- No loading coil losses
- Fits standard 3/8 x 24 mounts
Think twice if
- Clearance is ever a concern
- You don't have a heavy ball or spring mount
Nagoya CB-72 magnet kit
A short, inexpensive magnet kit with 18 feet of coax. Its listing is refreshingly honest: steel surfaces only, check SWR before transmitting, and it's a PL-259 kit for mobile CBs, not a handheld adapter. Expect the shorter 28-inch whip to trail a longer antenna in range.
- Whip28 in
- Magnet3.5 in
- Coax18 ft RG-58A/U, PL-259
- Frequency26-28 MHz
- VSWR1.5 or less under proper install (listing)
Why it stands out
- Low cost, complete kit
- Clear install instructions in the listing
Think twice if
- Range is the priority (short whip)
Mounts and coax that go with them
Most CB antennas thread onto a 3/8 x 24 stud with an SO-239 connector underneath. The Firestik K-4A heavy-duty stud mount (3,600+ ratings) fits any 1/2-inch hole. For mirror brackets, the Aries single-groove mirror mount and the 3-way aluminum mirror mount both include the SO-239 stud. For a flat roof or toolbox, Wilson's gum drop stud is made for surface mounting.
For coax, mini-8 beats thin RG-58 on loss. Two well-rated 18-foot runs: the Wilson 18-ft Belden mini-8 with PL-259 and FME, whose small FME end is easier to feed through a firewall hole than a PL-259, and the RoadPro 18-ft mini-8. Coil any extra loosely rather than cutting it after the antenna is tuned.

| Nagoya CB-72 | 28 in whip | Magnet | 18 ft RG-58 | Budget starter |
Install checklist
- Pick the highest mount your truck allows, with at least half the antenna above the roof.
- Make sure the mount is bonded to bare metal on the chassis, or use a ground strap. Paint and plastic brackets are the usual culprits for sky-high SWR.
- Route coax away from sharp edges and door seals, and don't pinch it in a door.
- Tune with an SWR meter on channels 1 and 40 before you talk on it for long (step by step here).
- Keep it legal: no amplifier (95.939), and channel 9 is reserved for emergencies and traveler assistance (95.931). Our CB channels chart lists the rest.
Still choosing the radio itself? The best CB radio guide covers in-truck and handheld units. Running a trail group? Read GMRS vs CB for off-roading first; many groups end up with both. For the GMRS side of the truck, the best GMRS antenna guide covers NMO mounts and 462 MHz whips.
