This is post 2395 in a continuing series of simple ham radio antennas.

End Fed Half Wave Antennas are simple, compact, and highly portable.  The secret to an effective EFHW antenna is the 49:1 transformer which matches the impedance of your transceiver to the extremely high impedance of the antenna itself.

In this video, "Tech Minds" shows us how to build a basic 49:1 UnUn which will protect your transceiver as well as deliver maximum efficiency for the antenna.

Here are some general comments from "Tech Minds":
