My station

My antenna

Today, a 272-foot Delta Loop in the backyard trees. Before that, a 135-foot wire and a 49:1 UNUN. It does not take much to enjoy ham radio.

Today my antenna is a Delta Loop made of 272 feet (83 meters) of wire, with a 4:1 balun. In the photo, the arrows point to the path of the wire through the backyard trees.

My first antenna

A wire up to the tree

As soon as I moved into my new home in St. Louis, I decided the best option was to run a wire up to one of the trees in the backyard.

It was a 135-foot end-fed wire antenna. The photos below are of the second one I built; the first was identical and ran west to east.

The 49:1 UNUN was built by Emigdio, WA3RF. Many thanks, Emigdio, for your time!
