Description

WHEN THE CD50-65-70 GETS MOUNTED ON A VEHICLE GUTTER OR SIMILAR POSITION, THESE UHF MOPOLESTM PROVIDE OPTIMUM PERFORMANCE WITH A LARGELY OMNI-DIRECTIONAL PATTERN. DUE TO THE LOW ANGLE OF RADIATION INHERENT IN THE DIPOLE ANTENNA PATTERN, A 4.0 DB IMPROVEMENT IN PERFORMANCE IS TYPICAL WHEN COMPARED TO A 3 WAVE WHIP IN THE CENTRE OF A METAL ROOF.  

THE END FED DESIGN OF THE UHF MOPOLESTM INCORPORATES A TRULY UNIQUE TRANSFORMER IN THE BASE SECTION. IN THIS PATENTED FEED ASSEMBLY, THE DIELECTRIC OF THE COAXIAL FEEDER CABLE IS TRIMMED TO A SET LENGTH AND THEN INTRODUCED INTO THE COIL IN TERMINATION. THE RESULT IS A PRECISELY MATCHED FEED WHICH IS SO CONSISTENT THAT TUNING TO FREQUENCY FROM A CHART BECOMES A MATTER OF COURSE.
