10nF DC-blocks at input and output, 4k7 pullup and 10k pulldown at the base, 180 ohms pulldown from the emitter, 12V input voltage having some 100n coupling capacitors. BC547 as transistor (should do 250 MHz?). I built that from schematic of 10 MHz distribution amplifier but with dirrefent transistor (there was BC849C in the schematic) and without LC-filters at output. -- 73s!
