TV Antenna Performance Evaluation with RF Pulse Techniques

One of the most critical performance characteristics of a TV antenna system is its ability to transmit a ghost-free picture. RF pulse techniques have been developed to evaluate this performance characteristic. Such measurements can be made to simulate the actual operational conditions of the antenna system very closely. During the past years, several RF pulse-measuring methods have gained acceptance here and abroad. The principles of some of these techniques are presented here and their advantages and limitations are evaluated. Additionally, some instrumentation problems are presented and precautionary steps indicated.
