MV3A has 4 band capability—2m/6m, plus 2 HF bands though use of loading coils. The MV3A is supplied with HVC28 (10m) loading

coil. There are four optional HF coils available: HVC7 (40m), HVC14 (20m), HVC18 (17m), and HVC21 (15m). The MV3A has a fold-

over structure which allows for entrance into parking structures (i.e. garages, buildings, etc.). Use DIAMOND model MX62M Duplexer

for single antenna operation with ICOM IC-706, Yaesu FT100 or for combining HF & VHF transceivers.

PRECAUTIONS:

(1)

The MV3A requires vehicle ground.

(2)

If installing HVC7 (40m) loading coil, install on top (vertical position) only. Some installations may require a nylon

cable to relieve stress on vehicle mount.

(3)

The MV3A 6m/2m tuning assumes that at least one loading coil is mounted at the top end. VSWR may be out of

specification without the coil(s).

(1)

Choose desired mounting location to insure maxi-

mum strength of mount, best performance of antenna, and

proper vehicle ground.

(2)

Assemble MV3A with desired loading coil (HVC28

10m coil is included in package) and install on vehicle mount.

NOTE: Metric Hex wrenches are enclosed.

(3)

With quality VSWR meter, check VSWR on all bands

to insure proper tuning of antenna. The loading coil rods

may require adjusting or trimming to reach best VSWR. If

it is necessary to trim coil rods, do so in 1/8" increments

only, until lowest VSWR is obtained at desired center fre-

quency. Shortening coil rods will have the effect of raising

the resonant frequency. Check both the high and low band-

width edges before cutting.
