Consider what W8JI says about end fed ants. He also addresses the PAR.
Interesting observation from one set of calcs he did- Maximum antenna
current is .758 amperes, while the coax common mode current maximum is
actually 1.02 amperes!

I would be cautious about using a transformer above 40 meters, as the
