The XTD-250Ka series are compact, self contained antenna mount power amplifiers designed for low cost installation and long life. Cooling and monitor & control systems are all self contained within the amplifier. By combining the power supply and the RF components within the same amplifier case the need for external high voltage cables (required for split box designs) is eliminated. This highly compact unit typically weighs only 48 lbs. This series of amplifiers provides several methods of tube protection.
