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.

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.
