I use a Navy Surplus Bird Professional Broadcast Dummy Load with a built
in watt meter rated at 1KW forever. I use it frequently to tweak the
Gates BC-500T for 160 meters or the Bauer 707 for 75 meters.
There are numerous surplus houses around the country that sell them and
depending on your pocket book can range from $250 to $1,500. I paid
$289.00 for mine last year and it runs cool when I put either one of the
Big Boxes into it.
Email me directly and I'll send you a digital photo, P/N and the name of
the place I bought it.
All the Best

Subject: [AMRadio] Dummy Load
I know this has been beaten to death many times, but for the sake of an
old
man with a bad memory could we discuss the most economical (very
important)
way to provide a dummy load for testing a broadcast transmitter. I have a
few Cantennas, but they get hot real quick at 1000 watts and I'd like
something I could be a little more confident in. If I were to use the
proper number of series/parallel non-inductive resistors at say 100 watts
each, what kind of support system would be best to insure at least a one
minute key down time? Would immersing them in oil or attaching them to
heat
dissipating metal with a blower be the better choice?
Thanks for any and all advice you may offer..
