When tuning optional loading coils (HVC7, HVC14, HVC18,

HVC21 and HVC28-10m coil), install on the top (vertical position) and

proceed to tune the coils by adjusting or trimming coil rods. (NOTE: HVC

Tuning Coils have a limited tuning range–refer to "frequency" under speci-

fications for bandwidth). Choose your desired center frequency as a guide

for tuning range and adjust for best VSWR at center frequency.

(5)

Once you have adjusted all coils for best VSWR in the vertical posi-

tion, you may assemble one optional coil horizontally. All coils can work

horizontally except the HVC7 (40m); it must be in the vertical position due

to its size. The VSWR will change slightly by adding a coil horizontal; there-

fore, it is best to check your VSWR readings to verify tuning.

To replace loading coils, simply unscrew coil from coil support

bracket and replace with another coil (see illustration). Be sure loading

coils are fastened securely so they don't loosen from vehicle and road

vibration.

(7)

The MV3A has a fold-over structure for situations where the

antenna height is a problem (see illustration). Simply unscrew the

fold-over lock, lift up, and tilt over 90°. Care should be taken when

folding over, not to damage vehicle or any loading coils. Do not

drive with antenna in the folded position.
