9:1, 4:1, 1:1 or None:None?
When using a Random Wire antenna (also known as an End-Fed Random Wire - EFRW), the impedance at the feed end of the wire is usually higher than 50 ohms.

Ham Radio? What’s that?
Now we have moved into the summer season I have been getting quite a few folks stopping by while I am operating in a public park.

Ham Radio & the Art of Bushcraft
Operating a radio in the great outdoors can be as simple as parking your vehicle, pulling a radio out of your pack, attaching an antenna to the top of the driver's window and keying up. I have done that myself in the depths of winter when it's too darn cold to really get outside and … Continue reading Ham Radio & the Art of Bushcraft
