NOTE:  After setting Volume Control at maximum position, connect Signal
       Generator to telescopic antenna input terminal (through suitable
       impedance matching network).  Standard output level is 50 mW at 25
       ohm (resistive load).

       Nominal Spec. represents the design specs, all units should be able
       to approximate these - some will exceed and some may drop slightly
       below these specs.  Limit Specs represent the absolute worst
       condition which still might be considered acceptable, in no case
       should a unit perform to less than within an Limit Spec.
