Dragon Super Heavy-Duty SO-239 Stud

With the newer heavier antennas on the market today, the old standard antenna stud mount may not be up to the job. Standard antenna mirror mounts come equipped with a standard chrome plated brass stud mount.

Brass is fine for the standard fiberglass whip antennas, but its a soft metal and the threads can strip from constant vibration from these heavy center-loaded antennas. In addition, the large coiled antennas create a great deal of wind resistance.

As well as stripped threads, other failures include corrosion to the completely snapping of the mount taking the antenna with it.

Some of these antennas run up to $150.00 for the high-power specialty aluminum types, which aren’t that heavy, but their open flat coil design does create considerable wind resistance.

The beehive type stud mount adds strength to the stud supporting with a rubberized plastic beehive shape molded section. At high power levels, this material has been known to break down and cause a resistive path for the RF signal to arc across.

This has caused intermittent SWR problems that were difficult to locate because the arcing generally occurred either under the mount or inside the beehive mount. Amplifier failure has been caused by these mounts!

The other weak aspect of this type of mount is the treaded portion where the antenna screws in. Still being composed of brass, this is still subject to failure.

The threads will still strip out of these mounts and if you weren’t paying attention, you could loose you’re antenna.

This is a great product and can be purchased from Bob’s CB & Wireless for $15.95. A heavy-duty stainless steel mirror mount without stud is also available for $10.95. These will give years of trouble free performance.
