(Hi George from your fellow, and temporarily - transplanted, South
Carolinian!)
For my Beverages, I've followed this approach anyhow. My termination
resistors are made from several 2W resistors in parallel, with the lead
lengths minimized. My unun is an FT-240-43, which is a 2.4 inch core
of type 43 material. Wire size is 22 - 24 awg. WHY??? Because I didn't
have
a rig/setup that automatically switched out the Beverage on receive, and
I frequently slammed 1200W into the unun/Beverage. A few of these slip-
ups caused me to design the system for my own personal late - night
FUBAR's.
cheers
73, Tom W4iU
