I was cleaning up today and came across an old dummy load I had that

like it is made from 2 watt resistors. ITs mounted on a quart size paint

lid and looks to be a 50 watts worth of resistors. This looks like it may
have been a commercially built unit and I was wondering what the power
handling capability would be if the resistors were submerged in mineral
oil.

Hi Jimmie, It would probably take a kilowatt, the question is for how
long? I was looking at my old Heath "Cantenna" manual and it says it
will take 1000 watts for about 1 minute in mineral oil. The resistor
element appears to be ~50-100 watts. The Cantenna is in a gallon paint
can. If none of the 25 resistors "fuse" out due to current, your load
should take a kilowatt for at least 15 seconds, and take 100 watts
~forever.

Thanks Gary
Would it be worth my while to remount it for a gallon container. I was
thinking of doing this anyway because the local paint store sells gallon
paint cans, Im not sure about he avaiability of the quart size cans. I have
access to lots of mineral oil. At work we use about 100 gal a year and I can
have all the used oil I want


That certainly beats going into a drug store and buying the 8 or 10
bottles of mineral oil I needed to fill up my Cantenna back in olden
days :-) Strange looks at the check out counter...
