Multiple antenna multiplexers, demultiplexers and antenna assemblies

An antenna system comprising:

• a first input configured to receive a communication signal from and transmit a communication signal to a cellular antenna operable for use with LTE communication signals;
• a second input configured to receive a satellite signal from a satellite antenna;
• a first notch filter coupled to the first input and configured to limit the satellite signal from passing to the cellular antenna;
• a second notch filter coupled to the second input and configured to limit the received and transmitted communication signals from passing to the satellite antenna;
• an output configured to output a combined signal including the communication signals and the satellite signal;
• a first matching circuit configured to adjust an output impedance of the antenna system;
• a second matching circuit coupled between the second input and the second notch filter and configured to match an impedance of the satellite antenna to a filter impedance of the second notch filter;
• and
• a third matching circuit coupled between the first notch filter and the second notch filter and configured to match a second notch filter output to a first filter output.

An antenna system comprising:

• a first input configured to receive a communication signal from and transmit a communication signal to a cellular antenna operable for use with operable for use with AMPS/GSM850, GSM900, GSM1800, PCS/GSM1900, UMTS/AWS, and LTE communication signals.
• a second input configured to receive a satellite signal from a satellite antenna;
• a first filter coupled to the first input and configured to limit the satellite signal from passing to the cellular antenna;
• a second filter coupled to the second input and configured to limit the received and transmitted communication signals from passing to the satellite antenna;
• an output configured to output a combined signal including the communication signals and the satellite signal;
• a single communication line routed from the multiplexer output for carrying the signals output by the multiplexer output.
• whereby the antenna system is operable via DC phantom power provided to the antenna system through the output.
