1. Firestrike K-4A 3/8-24 Stud Mount: Best Overall
In our evaluation, the Firestrike K-4A stands out for its premium 303 stainless steel construction and precise machining. Owner feedback consistently highlights its ability to survive years of road salt and weather without rust. The stud mount provides a solid foundation for tall antennas, minimizing sway at highway speeds. Based on spec sheets, the 4-hole bracket offers all-around positioning on most truck beds, though you will need to drill or use existing holes.
A real limitation is the lack of a no-drill option; if you cannot or will not drill into your bed, this mount may not be suitable. Additionally, the exposed stud can be a snag hazard if not capped. We recommend this for serious radio operators who prioritize long-term durability and are comfortable with a permanent installation.
- Precision-machined 303 stainless steel resists corrosion in harsh environments.
- Accepts all standard 3/8-24 antennas; compatible with CB, ham, and GMRS.
- Includes stainless steel hardware and a 4-hole bracket for secure mounting on bed rails or stake pockets.
Pros: Exceptional build quality and corrosion resistance.; Excellent RF grounding due to direct metal-to-metal contact.
Cons: Requires drilling or existing holes; not a no-drill solution.
2. Breedlove Mounts Stake Pocket Antenna Mount: Best No-Drill
The Breedlove Mounts Stake Pocket Antenna Mount is our top pick for those who want a no-drill solution. Based on owner feedback, installation is straightforward: slide the mount into the stake pocket and tighten the set screws. The powder-coated steel provides good corrosion resistance, though not as strong as stainless steel. In our research, users report stable performance with antennas up to 5 feet, though taller antennas may sway in high winds.
A common complaint is that the set screws can back out over time, especially on rough roads. We recommend applying thread-locker or checking tightness periodically. If your truck lacks stake pockets or you need a mount for a very tall antenna, you might want to consider a more permanent option. Otherwise, this mount offers excellent value for its convenience.

Cons: May loosen over time; periodic retightening of set screws needed.; Not compatible with trucks without stake pockets.
3. Wilson Antenna W100A No-Drill Mount: Best for CB
The Wilson Antenna W100A is a purpose-built mount for CB enthusiasts. In our evaluation, the clamp-on design is secure on most bed rails, and the included coax is a nice touch. Owner feedback indicates good performance with Wilson antennas, providing a solid ground plane and clear transmission. The NMO mount is a standard for CB and some ham antennas, offering a low-profile connection.
However, the mount is not universal; it only works with NMO antennas, and the bracket can mar painted surfaces if you don’t add protective padding. Also, the coax length may be insufficient for some truck cab configurations. We recommend this for CB users who want a quick, no-drill setup and already own or plan to buy a Wilson antenna.
- Designed specifically for Wilson CB antennas; NMO connector for quick swap.
- Adjustable bracket clamps onto bed rails without drilling.
- Includes 18 feet of RG-58 coax with PL-259 connectors pre-installed.
Pros: Easy clamp-on installation; no tools required.; Pre-assembled cable saves time and ensures proper connection.
Cons: Bracket may scratch painted bed rails if not padded.; Only compatible with NMO mount antennas; not universal.
4. Comet RS-730NMO Trunk/Lip Mount: Multi-purpose Mount
The Comet RS-730NMO is a flexible lip mount that can be used on truck bed edges or tailgates. In our research, owner feedback praises its adaptability, especially for those who switch between vehicles. The stainless steel hardware offers decent corrosion resistance, though the bracket’s moving parts may wear over time. Based on spec sheets, the mount can handle antennas up to 3 feet, but taller antennas may cause instability.
The main downside is that it is not as secure as a dedicated bed mount; off-road use can cause the bracket to shift. Additionally, the lack of included coax means extra expense and installation effort. This mount is best for users who need a temporary or multi-vehicle solution and are willing to accept some compromise in stability.

- Stainless steel bracket and hardware resist rust.
- Low-profile design minimizes wind noise and snag risk.
Pros: Can be repositioned easily; adaptable for multiple vehicles.; Low profile reduces theft risk and wind noise.
Cons: Not as stable as a dedicated bed mount; may wiggle on rough terrain.; Coax cable not included; must be purchased separately.
5. Larsen NMO 3/4 Mount with Cable: Professional Grade
The Larsen NMO 3/4 Mount is a professional-grade option often used in fleet vehicles. In our evaluation, the build quality is outstanding, with brass contacts ensuring low loss. Owner feedback from commercial users highlights its reliability in extreme conditions. The included coax is high-quality, but the mount itself is just the base; you’ll need a compatible antenna.
The biggest drawback is the requirement to drill a 3/4 inch hole, which is irreversible. This mount is overkill for casual users and may be too expensive for those on a budget. We recommend it only for serious radio operators who need a permanent, high-performance installation and are comfortable with drilling into their truck bed.
- Professional-grade NMO mount requires a 3/4 inch hole for permanent installation.
- Heavy-duty construction with brass and nickel-plated contacts for reliable RF performance.
- Includes 17 feet of RG-58 coax with connectors attached.
Pros: Excellent RF performance and grounding.; Durable enough for commercial and public safety use.
Cons: Requires drilling a 3/4 inch hole; not for renters or those avoiding permanent mods.; Higher cost compared to consumer-grade mounts.
6. MFJ-347 Magnet Mount: Budget Pick
The MFJ-347 Magnet Mount is a budget-friendly option for those testing the waters. Based on owner feedback, it works well on flat steel surfaces like truck hoods or bed caps, but the magnet strength is only adequate for moderate speeds. In our research, many users report the mount sliding off on rough roads or when hitting bumps. The coax is decent for the price, but overall durability is lower than permanent mounts.
We do not recommend this mount for off-road use or for tall antennas. It is best for temporary setups or for users who want to experiment with CB without a large investment. If you need a reliable mount for daily driving, consider spending more on a fixed mount.
- Strong magnet holds antenna on steel truck beds; no drilling required.
- Low cost entry point for CB and ham radio hobbyists.
- Coax cable with PL-259 connectors pre-installed.
Pros: Very affordable; easy to move between vehicles.; No permanent installation; simply place on any steel surface.

Frequently Asked Questions
What is the best location for a truck bed antenna mount?
The best location depends on your antenna type and truck configuration. For optimal ground plane, mount the antenna in the center of the bed or on the bed rail. Stake pocket mounts are convenient and provide a solid base. Avoid mounting near the cab to minimize RF interference. Based on owner feedback, a centered mount on the bed rail offers the best balance of performance and clearance.
Do I need to drill holes for a truck bed antenna mount?
Not necessarily. There are no-drill options like stake pocket mounts, clamp-on bed rail mounts, and magnetic mounts. However, permanent mounts that require drilling (e.g., Larsen NMO) offer superior stability and RF grounding. If you are renting or prefer not to modify your truck, choose a no-drill mount. For long-term use, a drilled mount is more reliable.
Will a truck bed antenna mount affect my truck's resale value?
Drilled mounts can lower resale value if left in place, but they can be removed and the holes filled with plugs or covered. No-drill mounts have no impact. If resale value is a concern, use a no-drill mount or plan to remove and patch holes before selling. Based on forum discussions, most buyers don’t mind small holes if they are professionally filled.
What is the difference between NMO and 3/8-24 stud mounts?
NMO (New Motorola) mounts are low-profile and common for VHF/UHF antennas; they require a specific hole size and are often used for ham and GMRS. 3/8-24 stud mounts are standard for CB antennas and offer a threaded stud that accepts various antennas. NMO mounts generally provide better RF performance for higher frequencies, while 3/8-24 studs are more sturdy for heavy CB antennas.
How do I ensure proper grounding for my truck bed antenna mount?
Proper grounding is critical for antenna performance. Ensure the mount makes direct metal-to-metal contact with the truck bed. Remove paint or powder coating at the mounting point. Use stainless steel hardware and consider adding a grounding strap between the mount and the chassis. Based on industry standards, a low-resistance ground path minimizes RF interference and improves signal quality.
Our Verdict
For most truck owners, the Firestrike K-4A is our top pick due to its exceptional durability and performance. If you prefer a no-drill installation, the Breedlove Mounts Stake Pocket Antenna Mount is an excellent alternative. Both options offer reliable RF grounding and long-term value based on our research.
