It seems that my 3 band EFHW project has grown into a 6 band antenna. The cold weather has meant getting some projects finished including putting the matching unit in a box. It is all ready to be installed and last night I did some tests which showed that it will tune from 21 MHz [...]

First contacts have renewed my interest in QRP. At the moment the rig is attached to an end fed half wave literally [...]

Like many others I have always thought that it was difficult  to match the high impedance of an end fed half-wave to 50 ohms. Not true! After reading the article I made a simple matching unit [...]
