The Big Kansas Coil is a lightweight, portable, and durable base loaded vertical antenna system that when paired with a telescoping whip operates on the 6 through 80 meter ham radio bands. This coil offers some innovative features, including: 3D printed construction out of engineering grade materials, integrated coil scale, easy to use adjustment collar, and a wider diameter coil than anything else on the market.

So what makes the big Kansas Coil different than other base loaded coils? First off is the construction. This coil is entirely 3D printed out of engineering grade Glass and Carbon Fiber filled Nylon material. This coil is lightweight and durable. The material is weather and heat resistant so this antenna is rated for up to 100 watts digital modes with a 50% duty cycle.
The second is its size, or diameter of the coil. This coil is wider than anything else on the market. In building loading or inductance coils, the diameter of the coil will affect the Q or quality factor. Narrow coils will have a very high Q and extremely sharp bandwidth on the lower bands. If you make the coil wider, the Q is reduced and you end up with more bandwidth. I’ll demonstrate what that means a bit later in this video.
