Band Configuration:
To change bands on the MFJ-1899T Portable Antenna, utilize the “wander lead”
by plugging it into the appropriate socket on the base coil. Fine-tuning can
be achieved by adjusting the telescopic whip.
Socket No1 is the first socket from te bottom.
Band Specifications:
Ground Plane Wire and Telescopic Section:
Lengths of the telescopic section are specified for the lowest frequency in
the band, and the ground plane wire should be connected to the radio.
The lengths for the telescopic whip, indicated in the table, are measured from
the base of the telescopic section where the metal section starts. The
telescopic section can be slightly adjusted for the best VSWR.
The optimal length for the ground plane wire must be more than ¼ wave of the
band you are shooting for.
Whip Configuration:
The whip can be unscrewed from the 12-inch base loading coil.
The antenna is ultra-compact, facilitating easy travel and portability.
It will handle up to 25 Watts of power.
Bonus Features:
With Jumper No1 connected to No6, the antenna transforms into a reasonable 5/8
wave on 2m and Airband.
Telescopic length on 2m is approximately 46.5” or 118cm.
Telescopic length on Airband is approximately 50” or 127cm.
