- Page 2 INTRODUCTION Thank you for purchasing the S9v 18’ Mk II multiband vertical antenna, hereinafter referred to as the S9v. We believe the S9v to be the lightest, most efficient and safest full-size vertical antenna available and we sincerely hope that you enjoy your new S9v.
- Page 3 If you want to use the S9v as a multi-band antenna, you will need a 4:1 unun and a quality antenna tuner in your shack. (Internal rig tuners do not have adequate range to match the higher impedances presented by the antenna on bands above 20 meters.) We recommend the LDG Electronics series of auto tuners for...
- Page 4 A 4:1 unun helps lower the higher impedances presented by the S9v on frequencies above 20 meters. Balun Designs sells two 4:1 ununs specifically for the S9v, depending on the amount of power you expect to run. These ununs may be purchased on-line at www.balundesigns.com:...

For permanent ground-mount installations, we suggest using a 2 foot length of ¾-inch galvanized plumbing pipe from a hardware store like Home Depot...
- Page 6 To create a mount for the S9v, simply install a U-bolt (not supplied) around the fiberglass mast about 12” from the top of the mast. The S9v will slip over the mast and rest on the u-bolt. You can then attach the four ¼-wave radials to the u-bolt using ring terminal connectors.
- Page 7 If possible position the radials equally around the S9v base. You may drop the radials away from the S9v at a 45- degree angle to the base, if desired, or lay them flat on a roof. Attach insulators to the ends of each radial.

- Page 9 S9v 18’ M k II Installation Guide _____________________________________________________________________________ ABOUT THE TUBE RINGS… The polymer tube rings are not clamps – they are “stops” that are used to keep the associated tube section from collapsing down into the tube immediately below it.
- Page 10 S9v 18’ M k II Installation Guide _____________________________________________________________________________ ABOUT THE TUBE RINGS (Con’t) Next, slide the ring down the tube to see if it fits tightly against the top edge of the adjoining lower tube. If the ring is not tight, slide the ring back up the tube, use your thumb and index finger to advance the latch ONE MORE CLICK.

Page 11: How To Unlatch A Tube Ring
S9v 18’ M k II Installation Guide _____________________________________________________________________________ HOW TO UNLATCH A TUBE RING Unlatching a tube ring is easy! Use both hands. Push forward on one tab while pulling back on the other tab to free the latching mechanism, as shown below. - Page 12 _____________________________________________________________________________ INSTALLING THE S9v 1. Select the Site. Try to use as open an area as possible to deploy the S9v. Even though the S9v is completely insulated, you absolutely MUST locate the antenna site at least 27’ away from power lines (1.5x the length of the antenna).
- Page 13 Radial Plate. (The S9 Radial Plate simply slips over the pipe.) 4. Assemble the S9v. To assemble the S9v antenna: a. Lay the S9v on the ground and unwind the vertical element wire away from the base tube in a straight line. Don’t pull unnecessarily on the wire –...
- Page 14 BOTTOM end cap where the wire exits. Put the top cap plug in your pocket so that it will not be lost in the grass. c. 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.
- Page 15 S9v 18’ M k II Installation Guide _____________________________________________________________________________ d. Gently pull the top, thinnest section straight out of the base tube (pull the section, not the cap) until it catches and pulls the next, lower section out. Gently twist the top section to lock it into the lower section. Now, pull the lower section straight out until the next section appears.
- Page 16 S9v 18’ M k II Installation Guide _____________________________________________________________________________ g. Next, slide the ring down the tube toward the lower, larger tube section. All tube diameters are tapered, so the goal is to have the ring fit tightly against the top of the adjoining lower tube section. You may have to slide...
- Page 17 Note how the rubber band is looped around itself on the tip of the connector. Now, remove the rubber band from the connector and unscrew the black plastic cap from the bottom of the S9v base tube. Next, poke the bare connector through the hole near the center of the black plastic cap and remove the cap.
- Page 18 S9v 18’ M k II Installation Guide _____________________________________________________________________________ n. To retrieve the vertical element wire from the antenna, use the hook tool to fish the rubber band loop out of the exit hole in the side of the base tube (as shown below).
- Page 19 S9v 18’ M k II Installation Guide _____________________________________________________________________________ 5. Raise the S9v. This is the fun part! To raise the S9v, simply grab it and lower it down over the ground pipe. 6. Connect Feed Line (or Unun) to Antenna. If you are using the S9v as a 20 meter monoband vertical, proceed with step “a”, below.
- Page 20 If you are using the S9v as a multi-band antenna (20 – 6 meters) position the Balun Designs 4:1 unun at the base of the S9v and connect the S9v vertical element wire ring terminal connector to the 4:1 unun stud marked Vertical.
- Page 21 16 radials, each at least 13 feet, 5 inches long spaced as evenly as possible around the S9v base. For best performance, use 32 (or more) radials. It is suggested that you use 14 -16 AWG insulated stranded copper wire (available at Home Depot and sold in a 500-ft roll for around $35).
- Page 22 If winds above 50 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 ring terminal connector from the coax center connection (or unun) and carefully lift the antenna straight up off of the ground mount.

(color becomes lighter), use a soft cloth and Armor to restore the finish. Automotive spray wax is also an excellent product to seal and protect the finish. The S9v may also be repainted, if desired, using a quality exterior spray paint such as Krylon or Rustoleum . - Page 24 S9v 18’ M k II Installation Guide _____________________________________________________________________________ SUPPORT If you have any questions or problems installing your S9v, please contact us.
