The Scorpion Antennas 680S, 680 & 6160 models.
All Scorpion antennas come with a 6 and 2 foot whip, the 2 foot is for 6 meters. 20 feet of antenna control cable, control box with a “coil at end of travel” LED indicator, snap together type ferrite core for the control cable, cigarette lighter plug with built in fuse holder. For mobile installs we supply a shunt tuning coil.

All antennas have a 3/8 by 24 stud with a stainless coupling nut already installed for the whip to be screwed into.

Our antenna body is .065 inch wall 304 Stainless Steel.

We use Delrin for the base of the antenna, the motor support, the ball bearing support, the upper coil cap that supports the whip. This material is extremely expensive, dense and heavy. Our finger stock and coil support housing is polished 6061-T6 Aluminum. It houses the tin plated finger stock and the one inch wide Phenolic coil support. The housing also works as a heat sink during high power operation. Our finger stock is special ordered tin plated beryllium copper and maintains 37 pounds of combined pressure on the coil at all times.

Yes, all steel gears – not plastic!
We use an Industrial grade robot motor that has steel gears in its planetary gear box. We install capacitors on our motors and ferrite beads on the motor leads so tuning the antenna by ear is static free. We are the only antenna manufacture that uses Two Double Sealed Ball Bearings for our coil support.

We use a 3/8 by 16 Stainless allthread in conjunction with a 3/4 inch piece of threaded oil light Bronze that is the nut. This assembly moves the coil in and out of the Stainless tube when rotated by the motor. The allthread is lubricated with very expensive Teflon grease that will withstand -30 to a plus 475 degrees Fahrenheit.

We use a 1/4 inch wall Industrial grade phenolic tube that has a heavy resin base formula that is specially manufactured to our specs. This is our coil form.

Our SA-680 coil is #10 gauge tinned wire wound at 6 threads per inch.
We have wound and tested every size wire at just about every thread pitch you can imagine and testing confirms that #10 gauge wire at 6 TPI on a 3 inch coil always produces the strongest signal!

We use the thickest coil cover in the industry. Our coil cover is made from Lexan, the same material that is used for bullet proof windows on armored trucks. We use .125 inch wall for all of our coil covers .

We are the only manufacture that has a built in counterpoise connecting bolts at the base of our antennas. This makes the backyard, field day or camping install of counterpoise wires a snap .

Our antennas come with the reed switch antenna position counter installed. We use a two pulse per revolution signal that gives better antenna positioning. Ameritron manufactures two digital readout antenna position controllers that work really well. One controller has memory presets and the other is a manual controller with just a digital readout.

Our antennas can be mounted three different ways:
Please remember this antenna weighs 18 pounds and has to have a rigid mount.

1. The Scorpion Quick Mount stud comes with a Stainless .750 inch by 2 inch piece of allthread installed inside it. The stud can be mounted to a bumper or a rigid mounting bracket.

2. A one inch pipe can be screwed into our Stainless One Inch Coupling.
The Stainless coupling screws onto the .750 inch allthread that is located at the bottom of the Scorpion Quick Connect
mounting stud.

3. We machine 6061-T6 aluminum round stock for a sleeve that is threaded. It is installed onto the 3/4 inch allthread on the Quick Mount stud. This allows the antenna to be installed onto a mast or piece of pipe that is mounted either on a mobile or a backyard install.

The Scorpion quick mount. This mounting system uses a 1.5 inch diameter by 4 inch long 6061-T6 Aluminum mounting stud that the antenna Delrin base slips over. A 1/4 inch button head screw that is longer than the other counterpoise bolts and marked red stops the antenna from rotating. The 4 inch quick connect stud is machined to accept a 3/4 inch bolt or allthread. We supply the allthread, washer, lock washer and nut for antenna mounting. With the Scorpion Quick Connect mount, you can move your antenna from your vehicle to the backyard in just minutes. Connect the counterpoise wires for vertical operation or install it onto the dipole support arm and you’re ready to talk to the world.

We use a Craftsman #3 Phillips for tightening the antenna mounts. We think this is one tool that everyone would have in their tool box.
