.Model S9v 31’ Multiband Vertical Antenna Installation Guide.Thank you for purchasing the S9v. The S9v is a tapered, ultra-lightweight 31’ vertical antenna designed for portable and fixed Amateur Radio use from 40 through 6 meters. We believe the S9v to be the lightest, most efficient and safest full-size vertical antenna available. Whether you’re at home or in the field, we sincerely hope that you enjoy your S9v.2:1 in the upper, SSB portion of the 40 meter band without an antenna tuner. So, if you operate a lot of SSB on 40, you may be able to use the S9v on 40 meters without using an antenna tuner. In this configuration, the coax feed line can be directly connected to the S9v.S9v 31’ Installation Guide When a remote tuner is used at the S9v feedpoint, a 4:1 unun is not required.
A 1:1 current choke balun may be required between the tuner and your transmitter if you experience RF current in your shack. (Burying your coax cable also helps minimize RF current from flowing back into your shack.).E openings. Ground or Elevated Mount A pipe or mast is required for the S9v to be mounted on the ground or in the air. For standard ground-mount installations, use a 40-inch long (minimum recommended length), 1-1/4” (1-5/8“OD MAXIMUM) galvanized pipe. You can also use our optional Portable Mount for permanent or temporary installations.S9v on the mast, simply install the optional S9v Pipe Mount Clamp 15” from the top of the mast. The S9v will slip over the mast and rest on the flat portion of the clamp assembly. In this elevated configuration, the S9v functions as a ground plane (GP) antenna and only 4 radials are required, as discussed below.S9v base.
If possible, drop the radials away from the S9v at a 45-degree angle to the base. Attach insulators to the ends of the radials.

Connect your coax shield to the clamp and radials. Do NOT run a wire from the radials/clamp/coax shield to an earth ground.S9v 31’ Installation Guide INSTALLATION – QUICK REFERENCE. INSTALLATION – DETAILED INSTRUCTIONS 1. Select the Site. Try to use a clear and open area to deploy the S9v.
Even though the S9v is completely insulated, you absolutely MUST locate the antenna site at least 46’ away from power lines (1.5x the length of the antenna).Drive the 1-1/4” (1-5/8” OD MAX) x 40-inch long pipe into the ground leaving 15 INCHES MAXIMUM above the ground. If you have purchased the optional S9v Pipe Mount Clamp, bolt it to the pipe an inch or two above the ground. 4. Assemble the S9v. To assemble the S9v antenna: a. Lay the S9v on the ground near the ground mount and unwind the vertical element wire from the base tube. Now, “walk the wire” away from the antenna base tube in a straight line.
Don’t pull unnecessarily on the wire –.S9v 31’ Installation Guide c. Now we are ready to extend the antenna sections. The S9v should still be laying flat on the ground.
To extend the antenna, grab a section of the wire near the bottom end cap and push the wire into the base tube. This action should cause the top, thinnest section of the antenna (it has a cap on its tip) to pop out of the top of the base tube.S9v 31’ Installation Guide e. All of the sections (except the top section) have been pre-drilled to accept a stainless steel screw (9 needed; 10 provided). Starting at the bottom of the antenna, grasp the base tube in one hand and twist and pull the.S9v 31’ Installation Guide h. The top section does not require a screw.

To secure the top section, hold the section below it with one hand and firmly twist and pull the top section out with your other hand until it is firmly locked in place.S9v 31’ Installation Guide 1. Hold top part of 2. Use your other wire firmly. Do hand to pull the not pull on this loose end of the part of the wire. Wire out of the base tube Bottom of Antenna Top of Antenna k.5. Raise the S9v.
This is the fun part! To raise the S9v, simply grab the base tube with one hand and the next section with your other hand and raise the antenna.Refer to the picture below. Wrap some electrical tape around the coax center and shield. Then, using the supplied stainless steel hardware, connect the coax center connector to the S9v vertical element wire. (The bolt head should face the base tube, as shown below.) Secure the coax center lead to the bottom of the base tube with electrical tape.S9v 31’ Installation Guide b. If you are using the S9v as a multi-band vertical, position the 4:1 unun (or remote antenna tuner) at the base of the S9v and connect the S9v vertical element wire ring terminal connector to the unun stud marked Vertical (or to the remote antenna tuner connector marked Antenna).16 radials, each at least 26 feet, 9 inches long spaced as evenly as possible around the S9v base – like wheel spokes. For best performance, use 32 (or more) radials.
How To Use Bosch Dishwasher First Time
It is suggested that you use 14 AWG insulated.If winds above 40 MPH and/or ice are expected, you should lower the antenna to protect it from becoming damaged. To lower the S9v, simply disconnect the vertical element wire from the coax center connection (or unun/remote antenna tuner) and carefully lift the antenna straight up off of the ground mount pipe.MAINTENANCE The S9v requires little, if any, maintenance. The S9v is finished with a durable painted surface, but it is subject to oxidation – just like an aluminum antenna. If you notice oxidation (color becomes lighter), use a soft cloth and Armor All restore the finish. SUPPORT If you have any questions or problems installing your S9v, please contact me.
