3 days ago · An antenna tuner is a passive electronic device inserted between a radio transmitter and its antenna. Its purpose is to optimize power transfer by matching the impedance of the radio to the signal impedance on the feedline to the antenna.
4 days ago · The receiving frequency of one of the two spacecraft had to be changed to match the transmit frequency of the other since the Orbiter-to-Lander UHF communication radios are used here for a direct link between the two orbiters, meaning one SC must either transmit at a receiving frequency or receive at a transmit frequency.
