How to make a shortwave Antenna Splitter

Here is a lost-cost solution to a common problem for shortwave listeners and ham radio operators. How to share one antenna among several radios (for listening only). A shortwave antenna splitter is needed. You can find HF splitters online, but they are not cheap. Let me show you how to save a few dollars.

Note: Do not attempt to transit through this setup. This is not intended for transmitting. Also, make sure you connect every tap to a 50-75 ohm load (ie: a receiver). Leaving unused taps will cause a mis-match and defeat the purpose.

I’ve seen other SWLs make their own splitters like Scottish Dxer Mark Borthwick, but without exact specs for the components, many of us are at a loss. Try this solution yourself, I assure you, there’s nothing inside these splitters that says for TV-only. Just look for ones with frequency specs so you know you’re covered.
