• End Fed Half-Wave Antennas - An interesting article on end fed half-wave wire antennas with a couple of original experiments. Author illustrate the role of the QRP matchbox, and a 40/20 meter antenna with a center stub making it a large bandwidth antenna for 40 and 20. Includes also an 80/40 end fed with the typical coil to make it available on 80 merts band.

• L-Match Tuner Build for QRP Operation - An L-Match tuner is a device that can add either inductance (L) or capacitance (C) to the antenna, bridging that gap between 5000 ohms and 50 ohms, thus matching it to the radio. The L-Match tuner is an extremely useful device that every QRP operator will want to have.
