Jeff...

An alternative is to get a remote current balun from RadioWorks.  These
baluns will take 3 to 4 KW and mount outside the house.  The open line
feader is conneected to the balum and then coax is run to the transmatch.
Tuning is straightforward.  I've used these remote current baluns with good
success.
