Sounds close, but you never knew exactly until you tried it (generally at
2:00 or 3:00 AM - to be finished and off the tower by 5 AM sign-on). 

The old quarter-wave "bazooka" isolation Rule was **very** precise (in old 
Sec. 3) and required **exactly** the same radiator base resistance with the
isolation connected as with the tower floating, although reasonable deviation
of reactance was permitted. 

IIRC this Sec. of the Rules was over half a page long in the same format 
you see in PDF's today. Depending on velocity up the tower, you might find 
the bonding point somewhat (whoops) higher than 90 deg free space above 
the base.

In the H-pol, mono days, before efficient iso-couplers "bazookas" were very
common for FM's mounted on tall AM towers and they worked very well. The
only problem was the tower had to be tall enough to have a 90 deg point
**below** the FM antenna feed point, and that could be a problem with an
8-bay FM. :)
