Build a random wire end fed antenna and make amazing contacts.

One of the easiest and least expensive HF antennas you can make is the basic random wire end-fed antenna.  The secret to this versatile antenna is the use of a 9:1 transformer and a good ground system.

In this video, Michael Martens (KB9VBR) takes us from start to finish in the construction of an end-fed antenna and its accompanied 9:1 transformer.

Random wire end-fed antennas are perfect for both home and portable use.
