CHAPTER 4
Preparation for Assembly
Choose a large clear area to work on your Ex-
plorer 14 antenna. The area must be at least
14' x 31' (4.27 m x 9.45 m) for the 30 meter
modification or 14' x 43' (4.27 m x 13.11 m)
for the 40 meter modification. You may wish
to drive a 5 foot (1.53 m) length of mast
material into the ground to attach the antenna
to while working on it.
Check all parts against the Parts List to make
sure no parts are missing.
All tubing supplied with the QK-710
telescopes together. Make all measurements
to the given dimensions, plus or minus, no
more than 1/8 inch! Double and Triple
checkALL dimensions after assembly.
Assembly of the QK-710 for 7 MHz
Operation
Select the capacity-hat clamps (Item 68) and
loosely assemble a set of four (4) clamps onto
each of the 1" x 6" tubes as shown in Figure
1. Center these clamps on the tubes, before
tightening.
Install a #10 tubing clamp at each end of the
1" x 6" tube and insert the 7/16" x 15" tubes
into the capacity-hat clamps. At this time
tighten all bolts used on the capacity-hat
clamp. Place 7/16" endcaps on the ends of the
15" tubes.
Remove the DE-3 (7/16" x 37") and the 1/2"
compression clamps (older system) or the #6
tubing clamp (new system) from the Explorer
14 driven element. Adjust the DE-2 to 37 1/2"
and slide the 15 meter trap all the way into the
DE-2. Retighten these two clamps securely on
both sides of the antenna. Loosen the sleeve-
spacer insulators and the sleeve boom-to-
element brackets and adjust the spacing of the
sleeves to 7 inches.
