How much would you be willing to pay for this?

The SGC 500W tuner is, as I recall, about $1500.. the Palstar 1500W 
autotuner is $1200, but not exactly designed for driving a vertical, nor 
is it in a weatherproof box.. The LDG is similar.

If you're willing to do some fabrication one could probably cobble a 
solution up for around $2K (box, remote controls, etc.)

A turnkey solution (like a kilowatt SGC equivalent) would probably be 
around $2500, if it were a product.  If you pay someone to design and 
integrate it from what's available today, figure more like $3-3.5.

I fully understand and support the desire for turnkey solutions (I've 
got better things to do with my *free* time than fiddle with modifying 
things and doing one-off packaging.. I've got a whole garage full of 
partially completed projects just like that.)

The market's just not that huge.. SGC sells theirs because it's a mate 
to their 500W amplifier.  Racal and Harris sell theirs as part of their 
overall system (and, without checking, I'd be willing to bet a cold 
frosty one that their kilowatt autotuners are more than $3K, and are 
probably not generic to boot.. that is, they have a custom proprietary 
interface to the rest of the radio.)

As another interesting point.. when you're getting into this kind of 
system design, then you should start thinking about remoting the PA, 
too.  Put the power amp AND matching network at the base of the 
radiator, and just run low-ish power to it.  With the new more liberal 
PA rules, maybe we'll start to see 30dB gain kilowatt amps that can be 
driven by a watt, with decent remote control.
