The even larger AT-5K is built very similar to its smaller brother AT-4K: a manual tuner with a T network design, with switchable balun for symmetric feeds. The max. power of the AT-5K is 3500 W CW (approx. 4000 W PEP). Due to the large capacitors the impedance range on the 10m band is limited. Operation on 10m is possible, but only with better adapted antennas.
