Build a random wire end fed antenna and make amazing contacts

The key to the success of this antenna is the use of a 9:1 balun to match radio to antenna.

In this video from Michael Martens (KB9VBR), we learn how to make this simple balun and use a few simple tuning aids.

Here are a few comments from Michael (KB9VBR):

Can a non resonant antenna be efficient? It sure can. I show you how to build a non resonant random wire antenna with a 9:1 transformer.
