3 X 4 Multiswitch
CM6244P supplies LNB power from the satellite receiver. At least one satellite receiver must be connected to it to pass VHF/UHF signals.
Solid copper center conductor RG6U coaxial cable must be used. It has a loop resistance of 1.0 ohms per 100 feet. At 300 mA, this implies a voltage drop of 0.3 V per 100. Never use copper clad steel center conductor cable which has a much higher loop resistance. As a result, to minimize voltage drops: (a) keep down leads from the multiswitch to the satellite receiver shorter than 75'. This will ensure proper switching action, and (b) keep cable lengths from the LNB to the multiswitch less than 75'. This will ensure adequate voltage to the LNB.

Ideal solution for DIRECTV, TiVo and FTA Satellite TV receivers
All Multi-Switches described on this page accept inputs from 13/17V and 14/18V switching systems, and are compatible with all the mini-dish systems on the market today.
How does it work?
When your satellite dish receiver is on, it normally sends one of two DC voltages up the coax to the dish antenna. This DC voltage normally tells the LNB (the receiver electronics in the dish) which of two bands of signal bands to receive. With a Multi-switch installed and connected to a dual LNB (one for each of the two signal bands), the Multi-switch see the "request" from a satellite dish receiver, it then switches through one of the signals. Your receiver does not react any differently when connected to a Multi-switch and the picture quality or signal strength is not degraded
Local Channels, no problem!
The Multi-switch includes an input for regular VHF/UHF TV signals. This can be an antenna on the roof or a signal from a cable TV provider. Use a
Diplexer at the satellite dish receiver to split the two signals (antenna/cable or dish). The Diplexer will allow a single coax cable to carry all the signals for the Multi-switch. One Diplexer will be required at each satellite dish receiver where you want the ability to watch antenna or cable TV channels. All four outputs do not have to be used.
