Coupled with any TransWorld Vertical dipole structure, your station becomes an on-the-air “Big Dog!”
Forget powering controllers, changing multiple switching arrays, or worrying with expensive control cables. All you
need is our transformer, a feed line, and a transceiver.
The Big Dog gives immediate access to several HF bands. It follows your transceiver and changes bands without
pushing any buttons, changing switching arrays, or re-tuning. You can work more stations in less time than ever
before. Plus, it is priced less than cumbersome switching arrays sold by other companies.
What this means:
Most radios will run happily without a tuner on 10–30 m; 20 m is exceptionally flat. On 40 m (and the upper end of 12 m), the transceiver's internal tuner may help some rigs achieve a perfect match, depending on structure size, orientation, and working conditions.
