Broadcast signal receiving system

A broadcast signal receiving system comprising an antenna, a transmitter connected to the antenna, a receiver connected to the transmitter in a wireless manner, and a broadcast signal receiver connected to the receiver, wherein

• the transmitter comprises
• encoding member to encode a broadcast signal which is output from the antenna,
• modulating member to modulate a wavelength of the broadcast signal encoded by the encoding member, into cm waveband,
• an adjusting member to set the wavelength of the broadcast signal modulated by the modulating member within the cm waveband, and
• a sending section for sending the broadcast signal modulated by the modulating member to the receiver in the wireless manner,
• the receiver comprises
• a receiving section for receiving a broadcast signal sent from the transmitter,
• demodulating member to modulate a broadcast signal received by the receiving section,
• decoding member to decode a broadcast signal demodulated by the demodulating member, and
• branching member to branch a broadcast signal decoded by the decoding member and to output the same to the broadcast signal receiver,
• the modulating member modulates a broadcast signal which is encoded by the encoding member into a wavelength which is set by the adjusting member.
