HF Mobile
Ham-tennaTM Whips
Power Rated at 250 Watts P.E.P.
These HF antennas are designed to operate over the phone
portion of HF bands with a typical VSWR of 2:1.
MFJ offers the following HF Mobile Ham-tennaTM whips:
MFJ Model No. Band MFJ Model No. Band
MFJ-1675T 75 Meter MFJ-1615T 15 Meter
MFJ-1640T 40 Meter MFJ-1612T 12 Meter
MFJ-1630T 30 Meter MFJ-1610T 10 Meter
MFJ-1620T 20 Meter MFJ-1606T 6 Meter
MFJ-1617T 17 Meter MFJ-1602T 2 Meter
Tuning Instructions:
Insert the whip into the lower section ferrule about four
inches and tighten the set screw. Screw the ferrule/whip
assembly into the lower fiberglass section. Install a VSWR
meter at the transceiver and apply 10 or 25 watts of power.
Adjust the VSWR meter and output frequency for lowest
VSWR reading, indicating resonance. If resonant frequency
is higher than desired, loosen the set screw and extend the
top whip until the desired resonant frequency is found. If
resonant frequency is too low, loosen the set screw and
adjust the whip further into the lower section. For best
results, adjustments should be made in small increments.
Caution: If required, cut off the bottom of the whip to ensure
it does not extend down into the coil. Failure to observe this
precaution will cause extreme heat damage and void the
warranty.
VSWR: At resonance, the VSWR should be 1.5:1 or less
when properly matched. When tuning is complete, tighten
the set screws securely.
NOTE: Bandwidth and VSWR will vary due to mounting
location. Roof mounts, trunk groove mounts, and trunk lip
mounts are recommended. The poorest mount is a bumper
mount. If your installation has a VSWR over 1.5:1 at
resonance or you need to operate over a greater bandwidth,
a tuner may be required.
STORAGE: To store your HF Ham-tennaTM, unscrew the
ferrule/whip assembly from the lower fiberglass section.
Note: If only the whip is removed, repeat tuning procedure
before using again.
