RECOMMENDED MOUNTS: K400C or K600M Trunk Mounts.
NOTE: THIS ANTENNA REQUIRES TUNING TO DESIRED OPERATING FREQUENCY. USE QUALITY VSWR
METER TO INSURE PROPER ADJUSTMENT. THE HF50CX REQUIRES PROPER VEHICLE GROUND.
MOUNTING LOCATION WILL AFFECT VSWR. NOT RECOMMENDED FOR MAGNET MOUNTS.
(1)
Remove antenna from package and inspect contents to insure it is complete. Attach whip element assembly #001701
to center loading coil assembly #001702. (Illustration 1 & 1A)
(2)
Choose desired mounting location to insure maximum strength of mount, and proper vehicle ground to yield best
performance of antenna.
(3)
Install antenna on vehicle. With quality VSWR meter, check VSWR for proper antenna tuning. Tuning adjustments
may be required to reach optimum VSWR.
Tuning of Antenna
Loosen element lock nut and slide antenna whip up or down. Tune until lowest VSWR is obtained at desired center
frequency. Tighten adjustment lock nut. Recommend using removable Locktite Threadlocker #242 or similar product to
insure proper fastening of setscrews and element assembly. (Illustration 2 & 3)
(Note: Mounting location and mounting structures will effect RF grounding and resonant frequency. If adjustment of whip
is necessary, adjust in 1/8-inch increments until desired resonant frequency is obtained.)
(4)
The HF50CX has a fold-over hinge for situations where the antenna height is a problem (see illustration 4). Simply
unscrew the fold-over lock, lift up, and tilt over 90°. Care should be taken when folding over, not to damage vehicle or
whip/loading coil assembly. Do not drive with antenna in folded position.
