I'd never want a diode of any flavor inside an antenna tuner if I
could avoid it.  Everytime I flow current thru a diode I get NOISE
someplace.  Thus--and it does work--in rotor control boxes, tuners,
radios, I almost always wire in about a 10-15% voltage drop in the form
of a resistor the first time I have to replace the bulb. I've not tried the new LEDS, they are a bit expensive I think but should be a good solution.
