Holland Electronics SBD Sub-Band CATV Separator/Joiner Blue

SKU CH-H9MM-3N3CG

A sub-band diplexer that combines off-air antenna and satellite signals onto one coaxial line or separates them at the far end, operating from 40 to 2250 MHz with 75 OHM terminators

  • ColorBlue
  • Weight0.15
  • Separates or combines antenna and satellite signals on one coaxial line
  • Single-cable installation simplifies local HDTV digital channel reception
  • Minimises off-air analog signal loss for cleaner picture quality
  • Converts one-way amplifiers to two-way operation at the head-end
  • Low-loss sub-band insertion across 40-2250 MHz range

Signal Combining and Separation

The Holland Electronics SBD Sub-Band CATV Separator/Joiner is a high performance diplexer designed for professional video distribution. It separates or combines off-air TV antenna and satellite signals onto a single coaxial feed line. Installers use one unit at each end of the cable run to merge and then split the signals. This device supports a single line installation for local HDTV digital channels.

Blue Housing with 75 Ohm Termination

The unit features a blue coloured housing and weighs 0.15. It operates across a 40-2250 MHz range with 75OHM terminators that insert off-air signals into four outputs of Phase III LNBFs. The design minimises off-air analog signal loss during the combining or splitting process. It connects an off-air antenna to a 1820DISH system efficiently.

Passive Operation and Return Path Support

As a passive diplexer, it draws no power and generates no noise or heat during normal use. The device allows one-way amplifiers to become two-way by separating return signals on head-ends. It provides low loss sub-band signal insertion within the distribution system or at the head-end. This ensures clean signal paths without active thermal management.
