To match the antenna output stage of a simple Amateur transmitter on the bands 80 and 160 meters are usually used FERROVIAL made on the basis of a unified regulator of the size of the rows (RRC-70) from the old TV models. But now the element RRS-70 not available. Instead I propose to use the feeder of lipstick. In place of a lipstick tube, install the ferrite rod and glue the appropriate frame for the coil. The rest (mounting, knob) depends on the taste of Amateur radio.
