Figure 4-3: Antenna Separation and Alignment
Installing Block Downconverters and
Each low-noise block downconverter (BCD) assembly includes a
block downconverter, a universal pole mounting bracket, and a
heavy duty band clamp. The BCDs can be installed either on a
horizontal or a vertical pole assembly.
MRC recommends attaching the downconverter directly to the
antenna. When you attach the antennas directly to the
BCD
RF
INPUT
connectors, then you must mount the antennas in the
same physical plane, that is, one antenna should not be tilted
with respect to the other antenna. See
To install the BCDs on a mounting pole when the antennas are
connected directly to the BCDs, perform the following steps for
each pair of antennas and BCDs:
1.
Fasten the first BCD onto the mounting pole and
secure it firmly in position using the mounting bracket
and heavy duty band clamp. See
.
Figure 4-4: Mounting Downconverter on Pole
2.
Connect the first antenna securely to the BCD
RF
INPUT
connector.
3.
Determine the minimum separation distance between
the two antennas per
4.
Loosely fasten the second BCD to the mounting pole
using the heavy duty band clamp. Make sure that the
BCD is approximately at the correct separation
distance.
5.
Connect the second antenna securely to the second
BCD’s
RF INPUT
connector.
6.
Adjust the second antenna so it is parallel to the other
antenna and separated by the minimum
recommended distance.
