Antenna Tuning Unit for 6-meters: by Igor Grigorov, RK3ZK

For experimental operation on the 6-meters range some antennas for others bands with ATU can be used, especially if a radio amateur only starts to work on the "magic" band. Schematic of such ATU that does match any antenna of 10-20 meters to 6-meters is shown on Fig. 1. The ATU allows match a load of 15 to 1000 Ohms with 50- Ohms coaxial cable or with end stage of the transceiver. Efficiency is not less than 70 %.
