Slip the Top Hat Assembly (the Hub) on the top element of the antenna. Install the Black Vinyl Cap
on the end of the top antenna element pushing it on as far as it will go.
Position the Top Hat Hub approximately 1/4 to 1/2” below the bottom edge of the Black Vinyl Cap.
Re-adjust the three bolts (
1-2-3 in Figure 18
) so the hub is centered around the top element. Take
care when tightening these bolts evenly, not to crush the top element. Once the Hub Bolts (
1-2-3
)
are properly tightened, tighten the hex nuts (
A-B-C in Figure 18
) which act as stop nuts.

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 (if used) are in the clear before
you begin.
