Owen,

The antenna is a short loaded vertical. The base is about 1.1 meters
long and 90mm in diameter, the coil is about 160mm long and about 80mm
in diameter, the top is 3 meters. The coil wire is 12 gage and the
spacing is about .5. As a model cross check, the impedance of the coil
measures about 60 uH.


So, what do you think its impedance would be? 1500+j??

This is probably accounting for somewhere between 5 and 15 ohms of
additional resistance, depending on Q.
