using a 5/16" nut driver. Be careful
not to lose the screws and nuts.
3. Place the large end of the 1 1/8" X
17" aluminum tubing over the end of
the loading coil assembly tube as
shown in Figure 1.
4. Secure the tubing in place with one of
the supplied hose clamps. Be sure to
place the connection tab between the
aluminum tubing and the clamp as
shown in Figure 1.
5. Place the remaining hose clamp onto the
aluminum tube. This clamp is used to

The AV
-
14AVQ should be assembled and
tuned using the instructions supplied with
the
antenna. The following section
describes the
preparations for the installation of the MK-
80 to
the AV-14AVQ.
PREPARATION
1. Assemble
the antenna using the supplied
instructions. Figure 1 on
page 4 of the
AV-14AVQ manual
gives approximate
dimensions.
2. In addition to normal assembly, hose
clamps need to be
placed above each
of the black covers on the traps.
These will provide extra strength to
the traps for the additional weight of
the MK-80.
a. Place one of the hose clamps
supplied
with the MK-80 directly
above the
black ABS cover of trap 11-
10.
Figure 1 on page 4 shows
the
location of this trap.
b. Place one of the hose clamps
supplied
with the MK-80 directly
above the
black ABS cover of trap 14-
15.
Figure 1 on page 4 shows
the
location of this trap.
c. Place one of the hose clamps
supplied
with the MK-80 directly
above the
black ABS cover of trap 15-
20.
Figure 1 on page 4 shows
the
location of this trap.
d. Do not place tubing section M5
onto the antenna. If this section is
3. Place the assembled MK-
80 onto the
assembled AV-14AVQ antenna. The
1
1/8" x
17" tubing has been fitted to
accept the AV-14AVQ.
4. Secure the tubing in place by
tightening
the hose clamp placed on the MK-
80
in step 5 of the assembly section.
5. Follow the instructions given to
choose a
mounting location for the
antenna.
NEVER IN
STALL AN ANTENNA
NEAR POWER LINES.
TUNING
Place the antenna in its final operating location
for tuning. Connect an SWR
analyzer to the
antenna with a suitable
length of 50 Ohm coax.
An SWR meter and
radio may be used instead
of an analyzer.
10,15,20 METERS
Tune the AV-
14AVQ according to the
instruction manual. Figure 1 on page 4
gives the dimensions for operation on 10,
15, and 20 meters. Remember to start
with
the 10 meter band.
40 METERS
The antenna length above the 20 Meter
trap is the frequency ad
justment for 40
below for proper tuning. Follow the
steps
below for proper tuning. Never cut
the
capacitance spokes on the rounded ends.
3
1.
Check the resonance of the antenna on
the
40 Meter band. The SWR should be
at a
minimum near 7 MHz or below.
2. To raise the operating frequency cut
small
lengths such as 1/4 inch lengths
from each of
the four 40 Meter spokes.
Check the
resonance point again.
Continue the previous steps until the desired
frequency is reached.
80 METERS
The 2:1 band-with on 80 mete
rs is
approximately 40KHz. The top
capacitance
spokes are adjusted to
change the resonant
frequency on 80 meters. Cutting the
four
upper capacitance spokes will raise
the
resonant frequency. Follow the steps
below
for proper tuning. Never cut the
capacitance spokes on the rounded ends.
1. Check the resonance of the antenna
on the 80 Meter band with the spokes
installed.
The SWR should be at a
minimum near 3.5 MHz.
2. To raise the operating frequency cut
small lengths such as '/4
inch lengths
from each of the four 80 Meter
spokes.
Check the resonance point again.
Continue the previous steps until the desired
frequency is reached.
