- Page 2 623-326-8780 Scorpion antennas, SA- 680, SA-680S “shorty” and the SA6-160, are supplied with a 6 foot whip, allowing efficient operation 10 through 80 or 160 meters. In addition, all antennas are shipped with 20 feet of antenna control cable, control box with two #31 type material split beads for the antenna coax and control cable decoupling, a cigarette lighter adaptor with fuse holder, and a shunt coil for antenna impedance matching.
- Page 3 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!
- Page 4 What follows are a few things to keep in mind when choosing where, and how to mount your Scorpion antenna. Please go to Breedlove mounts, Jerry has Scorpion Antennas listed on the main page of his site. He manufactures special mounts that will work with our heavy antennas.
- Page 5 While a large number of Amateurs use variations of a trailer hitch mounts, it is the least advantageous location. If you drive a pickup truck there are many mounting locations that will work quite well if the bed of the truck is properly bonded using tinned plated braid (strapped) from the frame to the body.
- Page 6 We Recommend using nothing smaller than 2" by 2" by 3/16" wall thickness..square tube for all right angle mounts that are attached to the frame of the vehicle and extend out to the side of the vehicle. Please Do Not take a chance with a lighter or smaller mounting material for your mount..it could break off and go through someone's windshield ! "See our mobile photo gallery"...
- Page 7 ANTENNA , YOU WILL VOID YOUR WARRANTY! Installing and Tuning the Antenna Matching Coil Your Scorpion antenna comes supplied with a base matching coil, sometimes referred to as a shunt coil. The shunt coil is almost invisible from the 20 meter band and higher frequencies.
- Page 8 “If your SWR is HIGH on 80 meters and it increases when you spread the coil then you need a coil with one more turn for a higher Micro Henry value”. It’s a balance of the SWR between the bands and this takes a few minutes of adjusting to find that sweet spot. If it is under 1.5:1, you’re done.
- Page 9 Our New sealed shunt coil enclosure Follow our 160 meter dual shunt coil enclosure instructions located on the previous page for installing our new sealed shunt coil enclosure for our 80 meter antennas the SA-680s “shorty” and our SA-680 standard.
