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

I have tested these and they seem to pass 40 -2050 MHZ just fine
The above model numbers describe the Channel Master range of satellite IF (950-2050 MHz) power dividers. These low cost, yet high performance units have many applications in satellite IF distribution systems. Functional diagrams for these units are shown in Fig. 1
The 2201IFD, 2401IFD and 2801IFD pass DC power from one output to the input (or in the opposite direction). Thus only one receiver supplies LNB power and controls any voltage switched polarization selection.
The 2202IFD and 2404IFD pass DC power from all outputs to the input (or in the opposite direction). Thus all receivers can supply LNB power. Care should be taken to ensure the input of a receiver will not be damaged by power from another receiver. Reverse powering protection is provided in many receivers and systems. These splitters are particularly useful where several multiswitches are combined together as there is no 0.8V drop across the diodes as in 2212IFD, 2414IFD and 2818IFD.Channel Master satellite IF muitiswitches include reverse powering protection .
The 2212IFD, 2414IFD and 2818IFD will pass DC power from any output to the input. There is a 0.8V drop across the diodes which are included to prevent one receiver from passing power back to another receiver. They are particularly useful in CATV headends as the multiple receiver LNB powering provides redundancy against losing LNB signals due to a receiver failure.
Unused outputs should be terminated to achieve optimum flatness, return loss and isolation. Channel Master terminators, Model 7184 (DC blocked) and Model 7190 (not DC blocked) are recommended.

These units are ultra wideband (40-2050 MHz) power dividers. They enable the splitting of signals on a cable carrying both VHF/UHF terrestrial TV channels (at 54-806 MHz) and satellite IF channels (at 950-2050 MHz). In each case, one output passes power to the input (or vice versa) and the others are DC blocked.
They are also useful in VHF/UHF MATV applications when a masthead preamplifier is used and it is desired to split the signal before the power unit, such as in the attic. They may also be used to split an MMDS IF signal at 116-408 MHz. It would be placed between the downconverter and set-top unit.
Unused outputs should be terminated to achieve optimum flatness, return loss, and isolation. Channel Master terminators, Model 7184 (DC blocked) and Model 7190 (not DC blocked), are recommended.
For applications which only require a passband of 950-2050 MHz, the Channel Master series of satellite IF only splitters should be used in preference to these ultra wideband models as they provide slightly better performance at lower cost.
