III. TRANSMITTER INSTALLATION (Continued)
4. ANTENNA CONNECTION: The transmitter is equipped with a 1 5/8" EIA flange connector
located at the top of the rack. The RF ATSC Compliant Mask Filter and output Directional
Coupler(s) are provided with the transmitter and are to be located and mounted at the
customer discretion. Pineapple Technology recommends the filter be securely mounted
above the transmitter cabinet but not in a position that could inhibit air circulation from the
top of the cabinet. The customer is responsible for the procurement and placement of the
RF cable connection between the cabinet 1 5/8” output flange and the 1 5/8 input flange to
the mask filter. The directional coupler is usually mounted on the output of the mask filter
convenient for connection to the station antenna transmission line. Two cables have been
provided for connection between the output directional coupler monitor ports and the
DXDPRO-10U Modulator. Conditions vary from site to site so some engineering may be
required to ensure that the antenna is receiving the correct amount of power to comply with
FCC licenses and to ensure safety from lightning, etc.
