- Page 2 ** Note, the quantity of these items in the kit depend on whether the multiband coil or standard coil kit is purchased.. All antenna hardware is the same for both kits, only the coil kit hardware will vary. Feed point insulator assembly Parts: PVC base tube (1) Aluminum end caps (2)
- Page 3 BNC connected to the antenna and the shell to the radials. PAC-12 standard coil kit assembly Full size coil kit assembly Note: If assembling the multi-band coil version, skip ahead to that section.
- Page 4 This is what the coils will look like when completed. The instructions below will step through the process of assembling and winding the coils for your PAC-12. The loading coils are assembled using the 2 larger end caps, the larger light gray PVC coil form, 4 of the 8-32 x 3/8”...
- Page 5 Compact coil kit assembly For winding the compact coils, use the same technique and winding chart as for the full size 6” coils. There is sufficient space on the form for winding coils for 30M and higher. The coil forms have 4 holes used for securing the ends of the coils during and after winding.
- Page 6 Determine the hole set to be used from the winding chart and pass the end of the enameled wire through one of the holes so that is passes through the coil form from one side to the other. If the inner set of holes are being used, pull enough extra wire to loop back through hole set A and to reach the screw on the end of the coil form.
- Page 7 PAC-12 Multi-band Coil Kit Assembly The PAC-12 multi-band coil kit is designed to replace a fixed coil in the antenna system to provide continuous tuning from 40 meters through 10 meters. The coil kit is wound with tinned copper wire and has a tap lead to adjust the effective inductance and tune the resonant frequency of the antenna system.
- Page 8 Contents: 1 PVC coil form 2 aluminum coil end caps 4 #8 screws and washers 3 crimp or solder lugs 1 roll of #18 tinned copper wire 1 clip lead 1” heat shrink tubing Coil Assembly: To assemble the coil kit, start by feeding the bare #18 wire through the holes at the end of the lengthwise slot along the coil...
- Page 9 Next, leave a few inches (~6) beyond the last turn on the coil and cut the wire from the spool. This end should be long enough to be passed through the holes in the form. Push this end trough the holes at the end of the coil as was done when starting the coil winding so that it comes out the other side.
- Page 10 Operation with multiband coil: The multi-band coil kit is installed into the PAC-12 antenna system by screwing it onto the top of the base rods and screwing the whip adapter and whip into the top end. The multi-band coil can be installed either with the tap lead up or down. The coil can be adjusted for operation on any frequency between 40M and 10M.
- Page 11 The chart and sketch are included on this page for assistance in finding the tap points for each band. This page can be printed and held next to the coil to aid in determining the tap location. This guide may be cut out and laminated and carried with the kit to aid in coil adjustment.

- Page 13 Telescoping Antenna Assembly Parts: 72” telescoping whip (1) Aluminum whip adapter 1) 8-32 x 1/4” Phillips head screw (1) To assemble the whip, slip it into the whip adapter until it hits bottom. If the fit is tight, it may require rotating the whip slightly while inserting.
- Page 14 First, separate the 16-conductor ribbon cable into 4-conductor sections giving a total of 4 sections of 4 wires each. Strip the ends of the wires back a half-inch or so, and twist them together. Crimp the terminal and use electrical tape or heat shrink tubing to strain relief the connection.
- Page 15 Also, use caution with the ground spike as the end is sharp and can cause injury. Do not allow children to play with the antenna. Assembling the PAC-12 To assemble the antenna, gather the parts that have been prepared. In addition to the components that you have already assembled, you will need the 2- 12”...
- Page 16 Once you are happy with the coil, you can solder the end to a solder lug or just leave it looped under the screw. Thank you for purchasing the PAC-12 antenna kit, please contact us via email if we can help in any way.
- Page 17 Q: How much power does it handle? A: The PAC-12 is rated to 100W of power when adjusted to a matched condition. Q. What is the difference between the fixed coils and the multi-band version? A. The only difference is the coils used. All other hardware is identical and it is possible to use both single band and multi-band coils depending on the application and operating situation.
