Palstar AT 4 k manual tuner from 4kw

If you really want to get a lot of power to antenna, then the Palstar AT-4 k is the right tuner. This is the tuner Palstar became well known for and it has since been continuously improved. The tuner has a max. 3000W power PEP (2500W CW) (actual loads). High quality components are designed for long life, because both variable capacitors are specified for 6 kV, the roller inductor and go up to max. HF power 10A. The use of three controls on t-matching (2 x variable capacitors, inductors roller 1 x) enables very precise and fine tuning.
Also the Palstar AT-4 k has a balun 1:1 switchable tuner input. Wire antennas or open wire end-Fed in this manner can be tuned directly. The balun is switched by a relay front panel. As with all great tuners from Palstar, Ta-4 k has a large cross-needle with backlight. Passage range from 300 to 3000W provides instant overview of back and forth power as well as the resulting SWR. The instrument has a "Peak and Hold ' function to read the peak values are more accurate and easier. Power requires 12V, max. 200ma.

Additionally the Palstar AT-4 k has a switchable 1:1 balun at the input of the tuner. This way end-fed wire or open wire antennas can be tuned directly. The balun is switched on by a front panel relay. As with all large tuners from Palstar, the AT-4 k has a large cross-needle display with backlighting. Switching meter range from 300 to 3000W provides instant overview of forward and reverse power as well as the resulting SWR. The meter has a ' Peak and Hold ' function to read peak values more accurate and easier. Power supply requires 12V, max 200mA.
