heathkit dummy load

[Robert A. Taylor]

The difference in heat dissipation between mineral oil and transformer oil
for practical uses of a dummy load are not  really significant.  Consider
power input vs. time power is applied to the load; for a given power input
here are the times the Cantenna can dissipate it for mineral oil and then
transformer oil.

375 w — both are the same at 30 minutes.
500 w — 19 min vs. 22 min.
750 w — 5 min vs. 12 min.
1000 w — 2 min vs. 9 min.

This data is from the Heath Cantenna specification dated 11-9-62.
