Mating the Vertical Sections to the Tilt Base
CAUTION: Attempting final assembly without proper precaution can be dangerous.
You should have someone help you steady the vertical antenna sections during
mating with the base section.
Note: A pair of sawhorses or ladders should be used to support the vertical sections
during assembly with the Tilt Base and whenever the vertical is tilted down. Do not
allow the tilt-base to support the entire weight of the vertical when horizontal.
When the upper element sections are assembled together install the black vinyl cap in place at the
top of the smallest element section.
Mate the vertical sections to the base tube section by sliding the bottom 2-1/8" OD element of the
vertical over the 2" OD base section element (which was previously mounted to the insulated
channel) to the mark you made on the tube earlier. See
Figure 11 . The two sections will have a
snug fit, so use a small amount of Penetrox A on the bottom section to make the fit easier. Slide the
band clamp down to the edge of the bottom section, between the slits, and tighten. Overall antenna
length from the top to the feedpoint is 43 feet.
Raising the Vertical
DANGER
: Make sure you have not inadvertently located the
antenna underneath power lines.
Residential power lines are often less than 40' high.
Contact With Any Power or Utility Lines Can Be Lethal !
The tilt-base certainly makes it easier however, this antenna can be challenging to put up the first
time or with gusty winds. If you have properly laid out your optional guy system in advance, it will
help keep the vertical stable as you raise it – and stop you from
going beyond vertical at the apex of the lift.
Make sure the optional guy ropes are in the clear before you
begin.
While raising the antenna, keep a constant pulling pressure away
from the Tilt Base. This will ensure that the pivot point bolt will
not jump out of the pivot slot and cause the tilt mechanism to
bind up and bend the bolts.
Starting from the top of the antenna, walk it up slowly using an overhead hand-over-hand motion,
maintaining a slow and steady pace.
