Time was, 100 watts was a lot of power. Today, more and
more transceivers feature 200 watts output. Even though many of these
modern radios feature a built-in tuner, it’s range and features are
usually quite limited; if you need a tuner, you probably need a better
one than they built into the radio. The LDG AT-200 is designed for this
new generation of rig. It's specifically reccomended for Ten-Tec and
tube radios.
Many QRP operators have a small 100-150 watt amplifier
for times when you need a few more S-units. The AT-200 is ideal for this
kind of operation; it’s minimum required power is only 5 watts, but it
will handle the higher power as well.
The AT-200 will handle up to 250 watts SSB or CW on 1.8 – 30 MHz, and
100 watts on 54 MHz. It features LDG’s state-of-the-art,
processor-controlled Switched-L tuner. It will match virtually any kind
of coax-fed antenna, including Yagis, dipoles, inverted Vs, slopers,
loops, just about anything. It will typically match a 10:1 SWR down to
1.5:1 in just a few seconds. You can also use the AT-200 with longwires,
random wires and antennas fed with ladder line with the optional LDG
balun.
The AT-200 features over 16,000 3D memories, automatically storing
tuning data for frequencies and bands as you use them. When you transmit
on or near a frequency you’ve used before, the AT-200 can restore the
tuning data almost instantly. It learns as you use it, adapting itself
to your operating patterns for faster and faster tuning. The 3D memory
system allows up to eight antenna settings to be stored for each
frequency.
Operation couldn’t be simpler: while transmitting a carrier, just press
the Tune button. An automatic tuning cycle will begin, then end a few
seconds later with the tuner set at the lowest SWR (almost instant for
frequencies stored in memory). Optional interface cables for Icom and
Yaesu make the entire tuning process a one-button operation.
The AT-200 is the latest in a long line of innovative LDG tuners. Get
the most out of your Kenwood, Yaesu, Ten-Tec or Icom radios that operate
at higher power.
