Elecraft T1 Portable QRP Auto Antenna Tuner

The Elecraft T1 Portable QRP Auto Antenna Tuner is the only automatic antenna tuner that’s sized to match today’s small QRP rigs. It’s one-fourth the size of most other compact ATUs. And at just 141,7g, the T1 is the ideal backpacking accessory.




Elecraft T1 Portable QRP Auto Antenna Tuner

The compact dimensions 215×74×62mm and the weight of 623g make it an interesting transceiver for portable operations.

Main Features

Use with any Low-Power Transceiver
The T1 can be used with any 0.5-W to 20-W transceiver covering bands in the 160-6 m range. This includes kits, home-built rigs, and commercial transceivers such as the Icom IC-705, mcHF SDR QRP, etc.


Quick, Convenient, and Accurate
The T1’s 7-inductor, 7-capacitor L-network provides a wide matching range, and its re-tune time from memory is just 1 to 2 seconds. Equally important, the T1 always tries to achieve a 1.0:1 SWR-it doesn’t stop at 1.5:1 or 2.0:1 like some tuners. You won’t even need to change modes to tune. You can use SSB voice or a keyer as well as a constant carrier (AM, FM, CW, etc.).

Factory-Assembled or Complete Kit
You can purchase the T1 assembled and tested, or as an easy-to-build kit. Our professionally written, fully illustrated assembly manual provides step-by-step instructions, and no alignment is required.

Unsurpassed Technical Support
If you have any difficulty, our technical support via telephone and the Internet will get your T1 up and running quickly. You can also get answers to nearly any question day or night from the helpful, tech-savvy hams on our e-mail user group.
