The 6MSSB-EXT lowers the 6m resonant frequency of MV3A for 50.1 operation.

NOTE: With 6MSSB-EXT installed, you will lose 2m capability of MV3A.

Installation: (You have two installation options.)

(1)

If using one HF coil, simply install in horizontal loading coil support bracket #67402. Follow tuning

instructions below.

(2)

If using two HF coils, remove set screw #67403 from horizontal loading coil support bracket #67402. Attach

6MSSB-EXT and fasten lock nut. Follow tuning instructions below.

Tuning Instructions: With quality VSWR meter, check VSWR on lower portion of 6M (approx. 50.125 MHz). The

extension rod may require adjusting or trimming to reach best VSWR. If trimming is required, do so in 1/8" increments

only, until lowest VSWR is obtained. Shorting extension rod will have the effect of raising the resonant frequency.

Check both the high and low bandwidth edges before cutting.

SSB extension rod for MV3A

(1)

Bolts and set screws on antenna and mounting bracket may

loosen from vehicle and vibration. Be sure to check periodically to

ensure they are fastened securely.

(2)

Avoid obstacles such as tree branches or low overpasses;

impact with these obstacles will cause antenna to break.

(3)

The MV3A is not recommended for either magnet type mounts

or installation on large GVW vehicles.

(4)

Avoid touching antenna while transmitting.

(5)

Do not scratch or remove rubber covering on loading coil

sections.

(6)

Avoid driving with antenna in folded position.
