NOTES:

(1) As measured with 5 dB pads installed at each NC input port.

(2) Output levels of 23 dBmV/channel, 79 CW NTSC analog channels from 54-550 MHz with 450 MHz QAM loading 6 dB below analog carrier levels.

(3) This is the noise figure of the gain stage only. Like any active combiner, must add input pad value (5 dB) and 8-way combiner loss (12 dB), yielding typical net noise figure of < 25 dB.

(4) DC load current at +24 VDC.

OTHER NOTES:

Note that NC to BC measured goes through a gain stage, so measurement appears high.
