The 5 kW night array used all twelve, with field ratios, W to E, of 1.0, 
2.0, 2.0 and 1.0.

The three towers N to S had the usual field ratios of 1.0, 2.0 and 1.0, 
or pretty close to those.

There was barely enough land for the original 12 towers, let alone 15, 
which would have been required for a 5 by 3.

If 15, then 10 kW or perhaps 25 kW was contemplated, but it would have to 
be one of those as this was still in the "discrete power" days, and there 
was only 5, 10, 25 and 50 kW to choose from.

As it was, the east-most part of the site was sold to K-Mart Corp, for 
use as a parking lot, and the east-most three towers were removed.

... where I have re-oriented the reference to the current reference, not 
the old one.

As can be seen, if three more towers were added to the site, those towers 
would be abutting the main N-S thoroughfare, but there does indeed appear 
to be enough room for fifteen towers, in a 5 by 3 configuration.

... idealization demonstrates that a fifteen tower, 5 by 3 configuration 
was just barely feasible, while retaining the original twelve towers.

As to whether Storer could have afforded the high cost of such a plant, 
well, that's another matter.


For, in the long run, it was very fortuitous that WTOP screwed with its 
night pattern, thereby allowing WLQV to upgrade from 3 kW and nine towers 
to 10 kW and the same nine towers, all at WTOP's and KSTP's expense!
