850-01 Antenna Practice Questions

Return Loss is the decrease of forward energy in a system when some of thepower is being reflected back toward the transmitter. What will cause high return loss in an RF transmission system, including the radio, cables, connectors and antenna?

• AA. A Voltage Standing Wave Ratio (VSWR) of 1:1
• BB. An impedance mismatch between components in the RF system
• CC. The use of cables longer than onemeter in the RF system
• DD. High output power at the transmitter and use of a low-gain antenna

What term describes the effect of increasing the intensity of an RF wave withan antenna by focusing the energy in a specific direction?

• AA. Distributed Radiation
• BB. Active Amplification
• CC. Beam Compression
• DD. Passive Gain
