    I did not put a balun at the feedpoint of my 20 m inverted V dipole antenna as I did not have the raw materials to make one. So I bought a 1:1 Current Balun from another ham. Before installing it for my 20 m antenna, out of curiosity, I thought of having a closer look at it. It is rated for 1000 W, though my radio is only 100 W. A lower powered option was not available. Frequency range is written as 500 kHz to 55 MHz. So I presume that I can use it for a 50 MHz or 6 m dipole at a later date if needed. I have bought a four band EFHW also along with it. If that works out well, I will not need the current 20 m dipole and I could repurpose this balun for 6 m experiments in future. On the lower side you can see the SO 239 connector for attaching the coaxial cable. Two connectors are seen on the upper side for attaching two wires of the dipole antenna. A nice stainless steel hook is there for attaching the balun to a non-conducting mast for an inverted V antenna.
