Hi All

Today I put together an EFHW antenna for 40-10.  In checking it out, the
SWR was good and all looked like it was going to work.  Made one contact
with it, running around 500 watts, and the core got really hot.  I am
assuming for around 600 watts, 1 core isn't enough.

I have some more cores and was wondering, for 600 watts. How many should I
use, 2 or 3?  I could put 3 together and make 1 core.

Running low power it works fine and doesn't get hot.  73
