Ed,
You are in the ballpark. A lot of folks are talking about 4.5 or 4.52 mw
into a dipole. Depending on how you figure line losses etc., you could be
right on. I haven't bothered to figure it out myself.
A half watt into a rubber ducky could also be about right, or a Kw into a
pin head.
Seriously tho, I have been planning a HiFER hand-held for use around here
using whatever power it takes to give me the right field strength.
You can use your 50 foot vertical just fine.
