[600MRG] Need loading coil inductance figure for new vertical

[WE0H-Mike]

Can someone model my new vertical and tell me what inductance I need to 
resonate at the low end of the 630m band?

Here is what my antenna will be. A 1" tubing 17' tall base loaded T 
vertical with a 80' single wire flattop. There will be no droop of the 
hat. I can pull it tight and it will use fixed fiberglass masts to hold 
the ends. I have a ton of radials all over the place if that means 
anything. It will use my current transformer coupling at the bottom of 
the loading coil. I only need the inductance figure as I can wind to 
that value on my existing coil form  and use my existing variomenter to 
fine tune it around the band.

I can't remember how I designed my now on the ground wire vertical many 
years ago :-(

Thanks a bunch,
Mike-WE0H
