Step #3 Install Lower-Element Mounting
Hardware:
Find the 1-1/8” OD x 3” radial sleeve (MA5VRS). With the mounting
holes closest to the top
(Photo-10)
, slip over the mast and align with the
4 pair of mounting holes, as shown.
Find eight X-pattern radial clamps (93). Also, find four 2” screws (20),
four lockwashers (41), nine flat washers (44), and five nuts (11).
Lay two radial clamps face-to-face to form a round mounting channel
for the radial rods. Install two mounting screws and place a flat washer
over each
(Photo-11)
. Insert the screws through the radial sleeve and
mast. Place a flat washer over each screw where it protrudes through
the mast.
Lay two more radial clamps face-to-face and install over the mounting
screws. Install a lock-washer on each and secure in place
finger-tight
with nuts
(Photo-12)
.
Repeat the above procedure, installing the remaining four radial clamps
finger-tight
. Temporarily secure the shield of the coax to one of the upper
mounting screws using the left-over flat washer and nut
(Photo-13)
.
The four 49” whips making up the lower element will be installed last,
when other work on the main element is complete.
Step #4 Install Upper Element:
Find the 1-1/8” x 48” element tube (MA5VBC). Also find two 1-
3/4” screws (31), two lockwashers (41), one flat washer (44), and
three nuts (11).
Slide the drilled and slotted end of the element over the mast and align
the mounting holes. (Photo-14). Install the 1-3/4” screw in the upper
mounting hole. Secure in place with a lockwasher and nut (this screw
is longer than necessary because it also supports the optional 6-Meter
add-on kit when purchased and installed).
Install the remaining 1-3/4” screw in the lower mounting hole and secure
in place with a lockwasher and nut, compressing the slotted tube against
the insulated mast.
Temporarily install the coax center-conductor on the lower mounting
screw using the remaining flat washer and nut .
Find the 1” x 48” aluminum tube (MA5VBD) and one large worm clamp
(411). Slip the clamp onto the slotted end of the lower tube. Install the
upper tube for an extended length of 40” and tighten (Photo-15).
