engineers developed a new coil using 3/16” copper wire with an aluminum
core. The result is a lightweight inductor with great power handling and a Q near 1000. The coil has a weather cover
made from polyethylene protecting the coil from birds, weather and snow build up. This allows for an almost lossless
REDUCED SIZE element. Countless hours have been spent optimizing all of our 40 meter antennas using this new coil
technique. The 40M3C uses simple element tip adjustments for optimizing performance for any part of the 40M band in
150 kHz steps. The 40M3C uses all of the same high quality hardware and machine parts that all of customers have
come to know. The 40M3C also has an optional 17m add on kit that uses a single feed point for both 40M and 17M. Don’t
miss the best part of the cycle, contact M2 for some help today.
