Combiner provides LPFing. SWR protection is included on the output. See: http://imagenisp.ca/jsm/VA7LF.html It has two settings: STUNT - 1200W KILL - 2400W and a little known possibility for a third setting but you really must be mad to suggest I try it. I have about double the PSU capability of what it needs but not the courage to try... I use a supplementary 400W amp to 'quantify' the antenna match then switch in the big amp. Just makes the switching requirements easier and safer for the system as a whole. 73 Scott Nick Mclean (SYD) wrote: > What design is your PA? > 73's > Nic McLean > VK2KXN / VK5ZAT > > >>> 1200W out and the rain is sizzling on the coil... >>> >>> silly boy...won't you ever learn? >>> >>> >> Natural coil cooling.... friendly to the enviroment, efficient and >> > free. > >> Hmmm. >> >> J. >> >> >> >> >> > > > This e-mail, and any attachment, is confidential.
