IZ1DFF ITALIAN HAM
KENWOOD AT 250
his is the latest object of
desire came to beautify and improve the efficiency of my radio station.
some time I was convinced that an automatic tuner would have been
necessary for me especially considering the fact that I don't have an
antenna park worthy of the name but "main" antenna is a home made
trap dipole for 20 meters.
This dipole, I do not know for what reason, managed to maintain a
low SWR also on bands of 12 and 10 meters and now,
automatic tuner, these bands are finally become usable without the
worry of damagingmy radio.
choice has been dropped without any shadow of doubt on the Kenwood
AT-250 because it is part of the same line of my Kenwood
TS-140S and I'm
happy to giving a touch of order and professionalism to my
antenna turner Kenwood AT 250 features:
antenna turner is capable of matching a 20-150 ohm load, or
approximatly up to 2,5 : 1 SWR
- Frequency range: all amateur bands incuded WARC (automatic
selection with Kenwood TS 430)
- Double possibility of power requirement: 120/220 Vac o 13,8
- Power meter (20 or 200 watt) or SWR meter
- Four output antennas
IN/OUT switch: when switch is OUT only a transmit signal passes
throught the antenna turner. With the switch set on IN, both transmit
and receive signal pass throught the antenna turner.
am convinced to have done an excellent purchase!
