1.	Which of the following devices assist in using the same antenna for transmission and receiving?(a) Monoplexer(b) Multiplexer(c) Duplexer(d) SwitchThe question was posed to me in semester exam.This intriguing question comes from Antenna Fundamentals in portion Antennas and Wave Propagation of Avionics
Answer» Correct answer is (C) DUPLEXER The explanation is: An antenna can transmit and receive at the same time as long as some means is provided for keeping the TRANSMITTER ENERGY out of the FRONT end of the receiver. A device called a duplexer is used for this purpose.
