The Antron 99 is a top-notch vertical antenna for the 10–12 meter bands. It comes with the Solarcon Twin Ring Adjust-A-Match tuning system. Additionally, this system lets users easily adjust the antenna for the best SWR across various frequencies. Adjusting the tuning rings up or down lets you get the antenna just right.
This versatility makes the Antron 99 a favorite among CB radio users and amateur operators that need a reliable base station antenna that works well.
Does the Antron 99 Require Radials or a Ground Plane?
The Antron 99 does not require ground radials for normal operation because it functions as a half-wave vertical antenna. However, adding a radial field or elevated mounting system can improve signal stability, reduce RF noise, and improve overall performance in some installations.
In addition to the elevated mounting option, ground mounting with a radial field can be used in amateur radio.
Lightning Protection and Station Grounding
Even though the Antron 99 is DC grounded, proper lightning protection is still strongly recommended. Use a grounded mast, lightning arrestor, and proper station grounding to protect equipment and reduce static buildup. Electrical grounding and RF grounding serve different purposes but both improve safety and reliability.
What Is the Antron 99 Antenna?
The Antron 99 is a 17-foot fiberglass vertical base station antenna designed primarily for CB radio but widely used on the 10 and 12 meter amateur radio bands. It is a half-wave antenna system with adjustable impedance matching that allows tuning across multiple frequencies without cutting the antenna.
The antenna is end-fed, which means feedpoint impedance can vary depending on mounting height, nearby objects, and feedline routing. The built-in matching system compensates for these variations to maintain an efficient 50-ohm feedline match.
Radiation Pattern and Signal Coverage
The Antron 99 produces an omnidirectional horizontal radiation pattern, allowing communication in all directions without rotating the antenna. When mounted at sufficient height, it also produces a low radiation angle that improves long-distance propagation and DX performance on the 10 and 11 meter bands.
Introduction to the Antron 99 Vertical Antenna
At 17′, it is a medium sized fiberglass antenna that was designed for CB radio, however, it works equally well on the 10-12 meter amateur radio bands.
This antenna stands out because it can be grounded with DC. This means you don’t need a ground to use it. It’s perfect for setting up in fixed or remote stations.

The Antron 99 is a top pick for base station operators with its Solarcon Twin Ring Adjust-A-Match Tuning System. Its popularity for local and DX operating shows how well it works with different radio systems.
The Solarcon Twin Ring Adjust-A-Match Tuning System
The Antron 99 vertical antenna is known for its light weight and three piece design. Additionally, the Twin Ring Adjust-A-Match tuning system lets users easily adjust the antenna’s input to get the best SWR across many frequencies.
This system has two metal rings that can be moved up or down the antenna. By changing where these rings are, you can tweak the antenna’s frequency. Moving the rings up raises the frequency, and moving them down lowers it. A good SWR meter or antenna analyzer will be needed for tuning.
This feature is a big deal for radio fans. It means you don’t have to cut the antenna when tuning, meaning you will not have to lengthen it if over tuned. With the Solarcon Twin Ring Adjust-A-Match, you can quickly make the Antron 99 work better for your needs.
- Easily adjust the antenna’s frequency by raising or lowering the twin metal rings
- Achieve optimal SWR across a wide range of frequencies for improved signal quality
- No need for complicated antenna modifications or replacements
Typical SWR Targets When Tuning the Antron 99
Most operators tune the antenna for these SWR ranges:
1.1:1 to 1.3:1 — excellent match
1.3:1 to 1.5:1 — very good performance
1.5:1 to 2.0:1 — acceptable but can be improved
Always tune at operating height and with the final coax installed for accurate results.
Basic SWR Tuning Procedure
- Install the antenna at final mounting height
- Connect an SWR meter or antenna analyzer
- Transmit on desired operating frequency
- Slide tuning rings slightly up or down
- Re-test until lowest SWR is achieved
Small adjustments produce noticeable changes, so tuning should be done gradually.
If SWR Will Not Tune Properly
Nearby metal objects detuning antenna
Loose or poorly installed coax connectors
Antenna mounted too low
Feedline routed near electrical wiring
Incorrect tuning ring position
Always verify installation before repeated tuning adjustments.

Using low-loss coax improves transmit efficiency and receive sensitivity.
Feedline Choking and RF Control
Because the Antron 99 is an end-fed vertical antenna, RF current can travel on the outside of the coax feedline if not properly controlled. Installing a choke balun or several turns of coax at the feedpoint helps prevent common-mode current, reduces noise pickup, and stabilizes the radiation pattern.
Recommended Coax Cable for Best Performance
Using low-loss coax improves transmit efficiency and receive sensitivity.
Under 50 feet — RG-8X acceptable
50–100 feet — RG-8 or RG-213 recommended
Over 100 feet — LMR-400 or equivalent low-loss coax
Feedline quality directly affects signal strength and noise performance.
Common Antron 99 Installation Mistakes
Mounting too close to buildings or metal objects
Tuning antenna at ground level before raising it
Using low-quality coax or poor connectors
Installing without proper mast grounding for lightning safety
Mounting too low for efficient radiation
Correct installation has a major impact on final performance.
How Mounting Height Affects Performance
Higher mounting height significantly improves signal coverage and reception. Installing the antenna above roof level reduces ground absorption and obstruction from buildings or terrain. Even an additional 10 feet of elevation can noticeably improve transmit range and receive clarity.
Takeoff Angle and DX Performance
Vertical antennas produce lower takeoff angles as installation height increases. A lower takeoff angle improves long-distance propagation by directing more signal energy toward the horizon rather than upward. This is especially important on the 10 and 11 meter bands where DX communication depends heavily on low-angle radiation.
