How to build a 40 meter loaded coil

Here’s an excellent “rainy day” project for radio amateurs.

In this video, Simon (VA7BIX) shows us how to build a sturdy, inexpensive 40 meter band load coil from locally available materials.

Simon takes us step-by-step through the design, construction, testing, and use of this useful antenna accessory. Make one for your next portable operation. The coil is lightweight and will fit comfortably in your emergency “go kit.”
