INSTALLATION
The 216 SAT OSCAR Beam may be center
mounted, and a fiberglass or other type of
nonconducting boom must be used to achieve
circular polarity. The boom-to-mast bracket
will fit booms with 11/4" - 15/8" diameters.
The DC switching cables and feedline must
be routed off the rear of the boom to achieve
circular polarity. A low loss cable such as
Belden 8214 or 9913 should be used with
UHF (PL259) connectors.
WARNING:
Do Not allow any part of the antenna to
touch power lines. This could cause
severe burns or fatal injuries.
NOTE: If you plan to use large diameter,
heavy coaxial cable or if it is likely that the
cables may accumulate ice, you will need to
adjust the position of the boom-to-mast
bracket on the 2 meter antenna boom for a
good balance. This bracket is shown between
horizontal elements D3 and D4. It may be
placed behind the horizontal D3, so that the
elevation rotator can turn freely in both
directions through the desired range. In
addition, counterweights may need to be
added to the front of the booms (if the 70cm
beam is also used) in extreme cases. The
coaxial cables should be secured high on the
vertical support mast to minimize the un-
supported weight.
When mounting the 216 SAT OSCAR Beam
above any other antennas, allow at least 6.5
feet for clearance of the rear boom.
When mounting the 216 SAT OSCAR Beam
on a common horizontal boom with other
beams, allow at least 5 feet (center-to-center).
The elements should be at a 45 degree angle
with respect to the boom. This will minimize
interaction between the antennas
SERVICE
If you are unable to resolve technical
problems, you should contact the Telex/Hy-
Gain Customer Service Department in
Minneapolis, Minnesota.
You should retain your sales receipt or other
proof of purchase for antennas that are still
under warranty. (See separate sheet for Telex
Warranty.)
