SCORPION SA- 680 Installation Manual Download Page 3

Our coil cover wall is the thickest in the industry, it is made of .125 inch Lexan. This is the same type material 
that is used for bullet proof windows on armored trucks, only a lot thicker.

 

We are the only manufacture that includes counterpoise or radial wire connecting bolts built into the base of our 
antennas. This makes backyard, field day or camping install of counterpoise or radial wires a snap.

 

Our antennas have a reed switch installed for use with digital display antenna controllers. We use two magnets 
mounted on the motor coupling that generate two pulses per revolution.....this equates to better antenna 
positioning from a Digital Antenna Controller 

The SA-680 coil has a Q of 410 and is wound with #10 gauge tinned wire, at 6 turns per inch.  
The SA-680S and SA6-160 coils have a coil Q of 380 and are wound with #14 gauge tinned wire, at 10 turns 
per inch.  

 

Unpacking and Installing the 

Scorpion

 Antenna 

 

Please read these instruction sheets completely before opening the shipping tube!

 

 
Your 

Scorpion

 antenna was carefully packaged to prevent damage during shipping. Failure to follow the 

directions could damage your antenna. Damage thus caused is not covered under warranty. 
 
1). Remove the packing tape from both ends of the shipping tube.  
 
2). 

There are 15 Phillips head wood screws safely holding the antenna in the shipping tube. Eight at the bottom of 

the tube, 3 in the middle of the tube and 4 at the top of the tube. All were located under the packing tape that you just 
removed. Please remove all of these screws.

 

 
3). Using two of the removed screws, partly thread them into the end caps. These screws can then be        

      used to pull out the end caps. 
 
4). Remove the end caps carefully! 
 
5). 

AT THIS POINT DO NOT TRY TO REMOVE THE WHIP, IT WILL NOT SLIDE OUT! 

 

6). Remove all the contents at the top end of the tube. This includes the Antenna Controller, Shunt      
     coil, and antenna control cable. 
 
7). At this point, you should see the ¾ inch threaded rod, washer and nut at the bottom end of the tube.    
     The whip is at the top end of the tube. 
 
8). Place the shipping tube in the upright position. Note the arrows and the word Top printed on the 
tube. 
 
9). The antenna will be stuck in the shipping tube from the indents of  the wood screws on two more 
wood  supports that hold the Antenna inside the shipping tube. Slightly bump the tube on the floor. 
This should release the antenna from the tube.  
 
10). Lay the tube on the floor, and pull the antenna out of the tube threaded rod end first! 
 
11). The 6 foot whip can now be removed from the body of the antenna.
