Full Size Coil Form - Pacific Antenna PAC-12 Manual

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" screws and four #8 lock washers.
Insert the end caps and align the holes
Install these one screw and washer in each end cap on the same side of the coil
form. The other side will be used for securing the coil windings.

Full Size Coil Form

Once the end caps are installed, the coil form is
ready for winding the coil. The coil form has a
series of holes used to secure the ends of the
winding. Depending on which band you plan to
construct the coil for, you will use different sets of
the holes. The full size coil form can be built for any band but it is typically constructed for the
40 or 60M bands and the compact coil kits used for higher bands. The charts show which set of
holes to use for each band.
