Introducing the Elecraft T1 20-Watt Automatic Antenna Tuner
and optional T1-FT817 Adapter
Ever wish you had a pocket-sized, high-performance ATU to use with
low-power 160 through 6-meter transceivers? The Elecraft T1 may be just
what you've been waiting for. It's one-fourth the size of other compact
ATUs, yet its 7-inductor, 7-capacitor L-network provides a wide
matching range and can handle up to 20 watts SSB/CW and 10 watts
AM/FM/digital. The T1 is the ultimate backpacking/HF Pack accessory,
weighing only 5 ounces (0.14 kg) including its internal 9-volt battery.
The T1 can be used with any 0.5-W to 20-W transceiver. This includes
home-built rigs, kits, and commercial transceivers such as the FT817,
IC703, Argonaut, SG2020, and many others. Users of rigs that have no
built-in transmit metering will benefit from the T1's 3-LED, 5-level
bargraph, which displays approximate power output at the touch of a
button, as well as SWR during auto-tune.
Coax-fed antennas such as dipoles, verticals, short whips, and beams
will work with the T1, as well as random-wire antennas, with our
without feedline. The T1 will allow most antennas to be used on
multiple bands -- in some cases covering the entire HF through 6-meter
range with a single wire. Balanced feedlines can be used with the aid
of a low-loss balun such as our model BL1.
The T1 always tries to achieve a 1.0:1 SWR -- it doesn’t stop trying at
1.5:1 like many auto-tuners. And you won’t even need to change modes to
tune, since you can use SSB voice or a keyer as well as a constant
carrier. Many L-C network settings are saved in the T1's EEPROM memory,
providing re-tune times of typically 1 to 2 seconds.
Other features include:
- auto power-off and latching relays for long battery life
- bypass mode
- ATU information report (present L and C values, battery voltage, etc.)
- low-battery warning
- reverse-polarity protection
- rugged enclosure
- quick-reference guide on the front panel
FT-817 Adapter (model T1-FT817)
Our “smart” remote control cable for use with the Yaesu FT-817 offers
the ultimate in antenna-tuning convenience. On any band change, a small
microcontroller built into the cable sends band data from the FT-817 to
the T1, which then recalls the appropriate per-band network settings.
This means instant QSY without the need to transmit -- less QRM, less
hassle. The T1's remote-control capabilities are fully documented in
the owner's manual so that users of other transceivers can create their
own T1 interface. (We may also offer adapter cables for other rigs in
the future.)
Pricing, Photos, and Further Information
The T1 can be purchased factory assembled and tested for $159, or as a
complete, easy-to-build kit for $135 (all surface-mount components are
pre-installed, and there's no alignment or test equipment needed). The
T1-FT817 remote control adapter is $49 (assembled only). For further
