40 Meter Antenna Tuner
1. 40 meter QRP antenna tuner.
2. Built-in resistive SWR bridge with led indicator.
3. Works with most antennas.
4. Simple series/parallel capacitor and toroid design.
5. One evening kit...easy to use.
The Matchstick will work with any transmitter with R.F. outputs of up to 10 watts. A switch places the variable capacitor in series or parallel with the inductor for high or low impedance antennas. Simply adjust the capacitor for the best match as indicaled by the brightness of the LED. Wait, there's more! On receive, the Matchstick improves selectivity and signal strength by acting as an input passband filter...you can hear the difference (on simple receivers).
