Abstract :
This article analyzes the performance of a 2-way supertrunk, 8.2 miles long, carrying 13 TV channels and a full complement of FM stations by means of FM modulation from a headend site to the system hub. Theoretical and actual performance are compared. Predicted group delay due to diplex filters in the amplifiers is compared to the measured delay before and after a simple correction.
