Temporarily out of stock

If you like to tinker with electronics, swapping out parts and measuring results, these EFHW Antenna Experimenter Boards are for you. If you are looking to build a kit to try out an end fed antenna, you probably should look elsewhere.

The boards are designed to accommodate:
-- coax ground to L2 or not
-- cap on primary or secondary
-- "traditional" winding with both L starting on shared ground
-- AA5TB style winding, capacitive coupled only
-- FT82-43 core, room for some binocular cores
-- experimentation with single band matching using Type 2 or 6 cores

Through holes for capacitors provided are intended for finer leads. Future boards should probably have larger holes for caps.

You should be able to operate with 100W with an FT82-43 core. Various other value toroids can be ordered from places such as W8DIZ and N4ESS

A quantity discount is available for Club and Group builds, 5 kit minimum order required.
