Band 11 Combining Filter. Enables the outputs of two cop-
phased transmitters to be combined into one out put, with a
maximum combined power of 400W. Connectors are N type
(female) with SOQ ports, frequency range 88-108MHz. A
monitoring output is provided. Level approximately -27dB
relative to the combined output. Parent equipment PA1/115.
Band II Combining Filter. Combines three FM Transmitters
of up to 200 watts each into a single aerial system. Can
be extended to combine up to five such Transmitters into a
single aerial system with additional components. Sub-units
FL1/S0A, FL1/S0B (4 x 200W and above). TCPD 1981.
4-Way Band 11 Combining Filter. This unit combines 4 co-
phase inputs, of up to 500W each, into a single output of
up to 2kW. The unit operates in the band 88 - 108MHz, and
contains internal balancing loads. 5U 19" Panel. Parent
equipment AM14/51A. DD 1981. DDMI 5.412(82).
Dual 2-Way Band 11 Combining Filter. This dual combiner is
of the Wilkinson type, requiring two co-phased inputs in
the range 88-108MHz to produce a single combined output of
up to 1kW CW. Two identical combiners are housed within
4U 19" rack-mounting.
