Driving circuit

Posted by Scott de Klerk on 12/4/2006, 6:34 pm

Hi all,
I'm trying to build a small antenna, driven at 10MHz by a current of about 10A. I figured that perhaps a straighforward modification of one the oscillating circuits driving the primary of a TC could be of use in powering the antenna.
Does anyone know of a good, reliable design that does the trick? I don't actually need very high voltages, just the current through the antenna (and the frequency.) The antenna should only consume about 300W, so it's not a particularly high power application.
It'd be nice if I could keep the driving circuit compact and use mostly solid state components, but I'll use bulkier analog devices if I have to.
Many thanks,
Scott
