The 4 State QRP EFHW antenna kit ($16) is a super cool little compact matching unit and antenna. It can be built as a random wire or an end fed half wave. The only thing you need to supply is the antenna wire. This is the first torroid I’ve wound and I’ve found their instruction easy to follow. I like this kit because it’s reasonably priced, easy to build, and versatile for the differing bands it can support.
