![]() The only difference between the Unun and Balun is how you connect the feed line.įor the antenna wire I have even used a spool of Mig wire in a pinch. You just need a single wire and a ground rod. I prefer a regular V where the Balun is near the ground and the elements extend up to two masts or trees, buildings etc nearby.Įven simpler is a long wire end fed antenna. In an inverted V you raise the Balun to a high point on a mast and the elements extend down to the ground. You can run the wire straight across the field or better yet use a V shape, either inverted or not. If you plan on stringing up a dipole you use 2 equal lengths of wire with the Balun in the middle. This is a 4:1 Current Balun.That means it can match a 200ohm antenna to a 50 feed line. An Unun is used to match an unbalanced line to another unbalanced line. ![]() A Balun is used to match a balanced line to an unbalanced line. I decided to make my own and did it for less than $5. To connect it to the radio I needed a Balun.These are such simple things but yet they cost so much from some places. A long wire and some insulators is pretty easy to carry. ![]()
