DIRECTIONAL MULTI-TAPS
The signals from any (4) polarity DBS dish are required
for multiple switches at multiple locations.
SDMST416
SOLUTION
SDMST412
Model SD MST416, SD MST412, SD MST409 and SD
MST406 multiple input taps directionally couple a
portion of trunk signals to feed single or groups of
DBS switches.
SDMST409
RELATED CONSIDERATIONS
Amplifiers are required to increase the signal level from
the dish to feed the taps. Model LAL204A-T includes
automatic gain control for a constant input to the taps.
The tap values are 16 dB, 12 dB, 9 dB and 6 dB. Model
SD MST416 tap output is 16 dB less than the input
