Trombone Line Phase Adjusters


 

INTRODUCTION

Trombone Line Phase Adjusters are needed at lower frequency applications where the phase adjustment of other phase adjusters is not sufficient. Also Trombone Line Phase Adjusters are designed for constant impedance over the whole adjustment range. They are employed to adjust the electrical separation of other components without introducing additional mismatch. All step discontinuities have been carefully compensated. Locking screws are provided to comfort the sliding tension and to lock at the desired adjustment. The best materials have been used, beryllium copper contacts assuring long life and noise-free operation, aluminum, brass and stainless steel parts for low weight, best performance and ruggedness, where needed. Stops at both ends of travel are preventing damage of the unit and do not allow accidental disassembly.
