UHV-6
Multi Band Mobile Antenna for
HF(7, 14, 21, 28MHz), 50, 146 and 446MHz
Features:
★
Developed for transmitting 50, 146 & 446MHz basically. With additional use ofHF-coils+ Elements, UHV-6 can be used
for 6 or 7 bands easily.
★
UHV-6 is developed for multi-purpose operation. Frequency characters of 50/146/446MHz, however, will keep always
best condition, irrespective of any additional use of extra coils and elements.
★
Combination use, with COMET duplexer, such as CF-530 or CF-706/CF-360, allows multiple TX and RX, at the same
time.
★
Free direction Fold-Over is convenient while parking the car in narrow space.

Frequency Adjustment:
★
50/146/446MHz. Basically, no adjustment is required.
1) In case of 50 / 146MHz, finer freq. control can be done, adjusting length of Element. Please unfasten the Ele. Fix
Screw.
2) HF bands Antenna length is shorted at each loading coils. Freq. control at each HF bands can be done, by adjusting
the length of each adjust Elements, extending or cutting little by little. When the elements were cut too much by
mistake, please use extra elements(90mm/2pcs. 550mm/1pcs.) involved in the package.
Frequency Shift by each 1cm are:
7MHz.........0.042MHz
14MHz.........0.25MHz
21MHz.........0.35MHz
28MHz.........0.5MHz
Note & Remarks
1. Please read through this Operation Manual initially, before assembling start, and find out the desired Frequency
Combination.
2. model UHV-6 includes many components. Before driving start, please confirm tight fastening of each Set Screws.
