Among the Palstar line of Antenna Tuners the AT1500CV was one of the most popular and best-selling tuners. The combination of affordable pricing and high quality construction and performance made this the tuner of choice for many Hams making the switch to Palstar from other amateur radio manufacturers. Now, in line with Palstar's policy of continual improvement, the AT1500CV has become the AT2K.
A newly-designed, smaller roller inductor allows the AT2K to tune 6 Meters, while a relay-switched toroid adds the extra inductance needed for 160 Meter coverage. Newly designed capacitors feature lower minimum capacitance for improved high band performance, while maximum capacitance has been increased to 400pF for better low band performance. In addition, the Peak/Peak Hold metering from the PM2000 has been incorporated into the AT2K.
The AT2K matches dipoles, centre fed doublets, G5RV's balanced feeders, Verticals, single wire, delta loops, beams, Windom's, Inverted An optional 4:1 balun for balanced wire feeders is required. Also featured on the AT2K is a bypass position for quick straight-through antenna connections with SWR/POWER monitoring.
The AT2K features a 6 position ceramic wafer antenna selector switch. Forward power metering is in two ranges, 300 and 3000 watts. A Peak/Peak Hold metering function is also provided. Standing Wave Ratio measurements are displayed with an illuminated cross-needle meter. SWR is read directly from the meter face where the Forward and Reverse needles cross.
The AT2K comes with classic Vernier dial plates for more accurate settings. As on all Palstar tuners, the front panel and top cover have powder-coat paint.
