Es muss nicht immer ein XXL-Tuner sein, um eine Random Drahtantenne an einen Empfänger und Transceiver anzupassen. Die provisorische Antenne kann direkt per Bananenstecker in die PL-Buchse des Tuners gesteckt werden.  Der Tuner kann für Frequenzen zwischen 160m bis 10m Amateurfunk und max. 200 Watt genutzt werden, allerdings sollte der Transceiver einen guten Endstufenschutz haben :-) Der MFJ-16010 arbeitet als L-Netzwerk. Wichtig! Tuner und Gerät müssen eine gute Erdung haben. damit ist dieser kleine MFJ-Tuner sicherlich kein Tuner für alle Fälle, aber einer für "die schnelle Anpassung primitiver Antennen" zum Testen...

The MFJ-16010 is a variable L-network random wire antenna tuner designed to match the low output impedance of your transmitter to the high impedance of a random wire (or vice versa). It will match almost any random length of wire to any transmitter from 160 thru 10 meters. The transmitter may have an output RF power up to 200 watts. For best results, the random wire should be as long, high, and clear of surrounding objects as possible. Do not ground the random wire antenna.

The connectors are labeled properly to match a transmitter to a higher impedance. This is the normal connection. To match impedances that are lower than your transmitter impedance (such as a mobile whip), simply interchange the normal transmitter and antenna connections to the MFJ-16010.

Remember the MFJ-16010 is designed to match a single random wire and not a coaxial line, even though coaxial connectors are used for both antenna and transmitter connections (these connectors make it easy to interchange antenna and transmitter connections).

A standard banana plug will fit nicely into the center of the SO-239 coaxial connector and can be used to connect the single random wire in lieu of a coaxial plug (PL-239).

A standard coaxial cable having an impedance that matches your transmitter output impedance, should be used to connect your transmitter to the MFJ-16010 Random Wire Antenna Tuner. Make sure the MFJ-16010 is well grounded to the transmitter.

If you are using the MFJ-16010 to match a vertical or mobile whip, the tuner needs to be at the feed point of the antenna and not at the transmitter end of the coaxial transmission line.
