Most if not all of these Channel Master Satellite products are discontinued. I just keep this web page up for reference.
I will try to have some alternative products listed
Satellite IF-VHF/UHF Diplexers
NEW CM # 4014 IFD $24.95 Use this 5 input 4 output Diplexer to add off air TV signal from an antenna on to a 2 LNBF system.
Model 4001 IFD Satellite IF - VHF/UHF Diplexer standard performance (for separating)
Model 4002 IFD Satellite IF - VHF/UHF Diplexer high performance
Model 4032 IFD as Model 40221FD except VHF/UHF DC Pass
The 4001 IFD and 4002 IFD diplexers are used for separating or combining satellite signals at 950-2150 MHz with VHF/UHF signals at 54-806 MHz. They include a high pass filter passing 950-2150 MHz and a low pass filter passing 54-806 MHz. In addition, a DC power pass is provided from the satellite port to the common in order to pass satellite receiver LNB voltage. In voltage switched systems, the receiver LNB voltage is nominally 13V for one polarization and 17V for the other.
The 4001 IFD is Channel Master's standard performance diplexer. This unit is ideal for separating satellite signals from VHF/UHF off-air signals when they are received in the customer's living room on one cable. The satellite signals are then connected to the satellite receiver's 950-2150 MHz input and the VHF/UHF signals are normally connected to the satellite receiver's VHF/UHF input. The satellite receiver then provides A/B switching as appropriate. Model 4OO1 IFD is also available in several wall plate models (see 4003 IFD, 4004 IFD).
The 4002 IFD offers higher performance (much greater stopband rejection) than the 4001 IFD. This is necessary when COMBINlNG satellite and VHF/UHF signals onto one cable because LNB noise extends down into the UHF spectrum and can degrade (add noise to) UHF TV reception if not adequately filtered out before connection to the distribution cable. Model 40121FD is identical except a DC Pass is also provided to the VHF/UHF input to power a preamplifier such as Model OO65DSB which is optimized for operation from a satellite receiver's LNB voltage.
Model 4022 IFD contains two 4002 IFD diplexers and a VHF/UHF signal splitter. When used with a twin LNB, diplexed satellite and VHF/UHF signals are provided to two locations within a building. Model 4032 IFD is identical except DC is passed from one output to the VHF/UHF input for preamplifier power.

DIPLEXERS ARE HANDY IN DSS AND ANTENNA SYSTEMS. SEE DIAGRAM BELOW . A GOOD WAY TO USE DIPLEXERS TO JOIN IN A DSS SIGNAL FROM A RECEIVER RUN INTO A UHF MODULATOR AND THEN RUN INTO A MATV SYSTEM
