ASSEMBLY
against corrosion if it is to be placed in concrete or damp, acidic or alkaline soil. Asphalt roofing
compound, polyurethane varnish or any other sealant that protects against moisture may be used. No
such protection is required for above-ground and most ground-level installations.
NOTE: hammering the mounting post into the earth may cause the insulator rod to splinter. If the post
must be hammered into the earth, protect the end of the rod with a block of wood. If a permanent
installation is not desired, a steel or other metallic tube having an inner diameter slightly larger than the
outer diameter of tube A w/insulator (A) may be used, by inserting tube a w/insulator (A) into this outer
tube for later removal. If the antenna is to be installed in an elevated position rather than at ground level,
please refer to the note following Step 20 below, and to separate roof mounting kit/radial information.
Use caution in handling the glass-epoxy insulators, for small splinters or flakes of this material may be
present and cause irritation to sensitive skin. Above all, avoid rubbing the eyes after handling this
material.
4. Prepare the coil Q base matching (Q) as shown in the pictorial drawing near the end of the
instructions.
5. Locate tube B1 section (B1) the extension tube on the parts page. This tube is 28" long and has a
greater outer diameter, 1 1/4" than any other tube. Slide the unslotted end of this tube over the
insulator at the top of tube A w/insulator (A), line up the holes and fasten it securely in place with a
#8 x 2" machine screw, lockwasher and hex nut.
6. Locate tube B2 w/insulator (B2). This is the other section of 2' x 1 1/8" tube, fastened to a glass-
epoxy insulator by means of a short machine screw.
7. Locate tube (B3). This is a 3' x 1 1/8" tube. Slide the unslotted end over the glass-epoxy insulator of
tube B2 w/insulator (B2), line up the holes and fasten securely by means of 1 1/2" machine screw,
lockwasher and hex nut. The completed sub-assembly of tube B2 w/insulator (B2) + tube (B3) may
now be removed to a more convenient place where dropped hardware can be more easily recovered
during the attachment of the 80 and 40 meter coils and capacitors.
8. Locate coil assembly 80/40 meter (C) and slide the clamp at the outer end of the larger coil over the
longer (upper) tube of the “B” sub-assembly, lowering the entire coil assembly until the middle
clamp can be positioned around the glass-epoxy insulator rod. The middle clamp may have to be
pulled open slightly to pass over the tubing and the bolt that goes through the
upper tube and the insulator rod. Position the center coil clamp around the
insulator rod so that the distance from the clamp to the end of either piece of
tubing is approximately equal, and pass a #10 x 1" machine screw through the
holes of the center coil clamp as shown in the drawing immediately below.
The outer tab of this clamp may be bent back slightly to provide clearance for
the bolt, and it may be bent back into place after final assembly. Fasten the
center coil clamp firmly in place using a split lockwasher and a wing nut. Repeat the procedure for
the two remaining coil clamps, tightening the wing nut only enough to hold the hardware in place.
Coil adjustment will be made later.
9. Locate the 80-40 meter capacitors, installed on a flat strip with a large center hole. Install the longer
capacitor bracket 80 meter (D1) on the larger capacitor, using a #10 x 3/8" machine screw and
lockwasher, see pictorial. Install the (smaller) capacitor bracket 40 meter (D2) on the smaller
capacitor, using a #6 x 1/4" machine screw and lockwasher. DO NOT OVER-TIGHTEN
CAPACITOR MOUNTING SCREWS!
10. Line up the hole in the center of the capacitor strip with the threaded end of the long #10 machine
screw protruding from the tab of the center coil clamp. Make sure that the capacitor bracket 80 meter
(D1) runs alongside the larger, 80 meter coil of coil assembly 80/40 meter (C). Fasten the smaller
center strip of capacitor assembly 80/40 meter (D) to the tab of the center coil clamp, using a flat
washer, a split lockwasher and a #10 hex nut. Finally, fasten the tab end of the capacitor assembly
firmly against the upper and lower tubes of “B” assembly by means of the two large non-adjustable
