Re: [Amps] 20kw Dummy load?

Hal,
Well, if you think about it, most plastics are petroleum based and will 
burn like crude oil. Just like an old tire burning, black smoke and all. 
I would have liked to had the picture. That could have been a bragging 
pic, telling everyone I did that after a long winded session..LOL!

About the load part. Nichrome wire is rolled out of round rod in some 
factories. Wonder if a piece long enough, say 1" in diameter, and was 50 
ohms, would make a good load? Maybe find some with something like 50 
ohms per foot or something. It couldn't be that inductive and should be 
lower than a non-inductive resistor I'd think. Also, other Nichrome wire 
is rolled from large diameter wire, about 3/8" to 1/2" when it comes 
from the mill. It would be possible to wind this like inside a 
non-inductive resistor (same patterns) and make a good load up. 20Kw is 
1000 volts at 20 amperes on a 50 ohm load so I'd think it would be easy 
to make?

Dear Robin,

I sure wish I kept a copy of the photo that was circulating around
Bechtel this past winter showing the result of a coax fire that started
at the base of a monopole and flared out through the coax ports
at the top. It looked like something you see in oil refineries....

Since we were putting in Multi-Carrier Power Amplifiers all over the
place,
and since there was a typo in the original SOW that specified "10KW
output power,"
I approached my boss and asked if one of the contractors turned the
output 
adjustment screw past 8'oclock, and he turned white as a sheet........

(The kludges being deployed would go into alarm at 200 watts, but
 what do managers know, they're only there for the tee shirt.)
