Mobile Antennas


Please contact us today for any additional information

The Scorpion Mobile Antenna will cover 10-80 meters. Our antennas are designed to be mounted on any vehicle including Cars, Vans, Pick-Ups, Buses, or RV’s.
We also offer a tripod mounting known as our Home Package for Backyard, Camping or Field Day Use.

Scorpion Antenna Mobile Package

Mobile applications set the focus for the initial requirements in the design of the Scorpion Antennas. Mobile operators need an antenna that will perform in all the different orientations a vehicle may operate, the highly interactive variable RF environment, and of course survive those “bird strikes”.

This antenna is built with physical security and survivability. Wind resistance, rotational and linear momentum forces, along with the “tugs” and “bumps” the antenna may encounter by people, tree branches, birds, other things that go “bump” in the night.

The Scorpion Antenna sits on a mount that is customer provided and must be rigid and securely attached to the vehicle frame. Mounting to a bumper clamp on mount or directly on car body sheet metal is NOT a secure mount point and NOT recommended by Scorpion Antennas. See the article “Mobile Antenna Mounts” for an example of a “pickup bed” and also the Gallery “Customer Mobile Installations” for visual ideas for mounting. Remember, the Scorpion Antenna will take a beating but to take advantage of it’s strength, it needs a secure and stable mount point.

Another point about mounting to the vehicle is a ground plane for the antenna. Remembering that the vehicle is the other half of the antenna! Not having the antenna mounted in an electrically sound fashion using good RF bonding of the vehicle sheet metal to the frame can be of a concern for “any” antenna’s performance mounted on any vehicle.



The high Q of the antenna coil is one part of the reason this antenna performs extremely well. The High Q coil means when the antenna is tuned to resonant operating frequency, all off center frequencies (noisy stuff) are reduced and the center frequency is stronger entering the receiver. That’s the trick, having a High Q coil and by using the right coil length and diameter, the proper shunt coil for impedance matching, and good vehicle bonding technique.

Speaking of Ground, your mobile vehicle is not all connected together, electrically, that is. All body panels are painted then bolted together. From a DC continuity stand point, just because the vehicle lights work, does not mean you have a good RF bond on the vehicle. “Bonding” is a must for any HF installation on a vehicle.

The other side of having a High Q coil is it can couple much easier to it’s environment. As the Scorpion Antenna moves down the road there are all kinds of objects that enter it’s near field signal and become coupled.

Objects can be other vehicles, trees, light poles & terrain. All of these things will effect the resonance of the operating frequency and will be seen in an VSWR change. And this does what? This means all the variables that define an antenna become dynamically changing. The High Q coil on the plus side means the swings in values have a “sharp” time impact and come and go quickly. That’s not a negative Q factor but a positive Q characteristic on side of performance.

The above is what we have experienced over the years using our antennas in a mobile environment 7 days a week.

Reviewing all the products in the Mobile group will explain some of the differences in design considerations. Review the other groups of antennas will give even more insight on performance and why we have different models. Not any “one” antenna covers all design considerations. It’s a compromise of how we adapt our High Q coil and manufacturing construction techniques that makes best fits for performance with Customer needs.

The Black Widow™

High Gloss Powder Coat Finish is available on our Antenna for an Additional $60.00


As far as paint goes, nothing will last longer or is more durable than powder coating. Motorcycle manufacturers through out the world use powder coating on their frames.
