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

5113IFD Satellite IF - 13 dB Line Amplifier

5213IFD Dual SatellIte IF 13 dB Line AmplIfier

The 5113IFD is a general purpose, low cost satellite IF (950-2050 MHz) line amplifier with 14 dB gain at 1450 MHz and appropriate gain between 950 and 2050 MHz to give cable slope compensation. Typical applications include:

i.  With long (greater than 100 feet) runs of coaxial cable from satellite receiver to LNB.

ii.  In a satellite IF distribution system where signal levels may have become marginal towards the end of the system.

iii.  Prior to splitting a signal many ways which might cause excessive splitting loss.

Note:

i.  Most satellite receivers are designed to operate with input signal levels between -60 and -30 dBm per channel. It is recommended that IF distribution systems be designed to give no less than -50 dBm per channel at the customer outlet.

ii.  Care should be taken not to overload the amplifier (see specifications). Depending upon LNB gain, this will usually involve leaving a minimum distance of 100 feet of RG6U between the LNB and the line amplifier.

iii.  The 5113IFD amplifier is not designed to be cascaded (see 5217IFD). If two amplifiers must be cascaded, there should be approximately 14 dB of cable loss at 1450 MHz between the two amplifiers. Then for the same distortion at the output of the second amp, the input level to each amplifier must be 3db lower than for one amplifier.

Model 5213IFD is similar, but includes two amplifiers in one housing. This is for dual cable, dual polarization systems. Note the diagram in Figure 2. Each amplifier is DC passive but both amplifiers are powered from the same side. This technique provides higher output capability.
