RF Output Assembly (971-0023-026/027/028)
The entire output assembly lifts out of transmitter and can be replaced as a complete
“module” at the user’s discretion. A procedure is provided below. To facilitate
assembly removal and insertion, it is possible to first remove the user interface sub-
panel and support brace on the transmitter rear panel to increase the size of the access
hole. However, this is not strictly required, as the output assembly can still be installed
without removing these items.
Certain aspects of the output assembly can be serviced in the field, notably the
combiner cables and ballast loads. Damaged ballast loads and cables are usually
evident from visual inspection. If cables are replaced, make sure that cables are
replaced with the exact same type (RG-142 and RG-302). Do not use RG-58, RG-59,
RG-223 cable under any circumstances.
