MFJ 1786 is the best performing and most convenient small space antenna available to amateurs today. It covers 10 MHz to 30 MHz, and features an indoor semi-automatic tuning unit with a built-in cross needle wattmeter. All tuning and control voltages are coupled to the antenna through the coaxial feedline for simple, neat, one wire installation. The loop antenna element is constructed from thick walled aluminum pipe, and every current carrying joint is welded to eliminate high resistance pressure contacts that reduce efficiency.
