[AMRadio] Dummy Load

I have a couple of Cantennas, but the last time I loaded the Henry into 
it for any length of time it got REAL hot.  The SWR was still fine, so I 
don't think she'll take high wattage very long.  I tried the same thing 
with an MFJ oil filled load (like the Cantenna) and it heated even 
faster.  I'd just like to have something I don't have to worry about 
while making adjustments. 

Thanks for the advice...
