DH Satellite 1PC or 4PC 3m, 3.7m, & 3.8m 48 Polar/Fixed Mount - Manual (Page 4)

ASSEMBLE
RING TO BASE CAN
Assembling the 48" Polar mount is very easy as there are only two major parts to put together.
Take the base can and set it over the base post. Tighten the set screws on the base can to hold it in place. Then take the
ring and attach the 8 bent back brace tabs to the ring. Take the 48" ring, which has the top cross members and the boom
tube pre-assembled, and set it up into the base can. You need to line up either the top or bottom hole on the boom with
the hole on the base can saddle. (See the various positions in FIG 1 BELOW for placing the hole on the boom with the
hole in the saddle) When you have them aligned either the top or bottom hole on the boom with the hole in the saddle,
slip in the 3/4"x 4 1/2" bolt. Make sure the bolts are secure but leave them slightly loose until you have lined the
antenna on the satellite you will be using. Once you have aligned the antenna please double check all bolts and nuts to
be sure they are tight.
Assembling the turnbuckle: Because of International demand this mount has been designed to be used
almost anywhere in the world. You will use one of the two locations on the base can to attach the turnbuckle
assembly. Please read the below in Fig#1 to determine the correct position you will use for the Turnbuckle assembly
for your latitude. You will use the front tab /position on the base can and the top hole in the boom for setting latitudes
of 0 – 26 degrees. You will use the back/rear top tab on the base can and the top hole in the boom for setting 39 -70
degree latitudes, the back/rear bottom tab on the base can and the bottom hole on the saddle for 24 -44 degree
latitudes, and the rear/bottom tab on the base can and the top hole in the boom for 33 – 55 degrees latitudes. We have
a longer threaded rod that can be installed in place of the Right Hand threaded rod for higher elevation /look angle
needs. (See figure #2 below)

Tabs on Ring
Use Rear, Top turnbuckle Tab
on base can and top hole on
boom for 39˚ - 70˚ latitude
Use Rear Bottom turnbuckle tab & bottom
hole in boom for 24˚- 44˚ Latitude
Use Rear Bottom turnbuckle tab & top
hole in boom for 33˚- 55˚ Latitude
Use Front turnbuckle tab on the
base can and top hole on boom
for 0˚ - 26˚ latitude
Notes on setting boom: Boom should be set on your Latitude when polar tracking. If using as
an AZ-EL or Fixed mount this is not a critical adjustment. The 48” mount is a polar tracking
mount with a locking bar for fixed satellite positions.
Elevation numbers are not look angles
To Get look angles of below 10 deg. you can do any of these options:
1. Turnbuckle in front using boom in top hole, using a 6” rods in turnbuckle, elevate to 20 deg,
remove locking bar and let antenna rotate to proper look angle and mark the locking bar and
drill 1/2" hole and fasten with 1/2" bolt.
2. Turnbuckle in rear top bracket of base can, use top hole in boom, elevate to 70 deg use long
rod in turnbuckle, remove locking bar and let antenna rotate to desired look angle mark the
locking bar and drill 1/2" hole , now fasten with 1/2" bolt.
3. To get lower look angle at any elevation you can move the declination adjustment bolts out
on the top and in on the bottom
When doing this adjust the bottom 2 and the top 2 bolts the same.
