> Mosley had a J-type tower. Have were ever figured out why some sites had them vice more conventional tapered ones?
To the best of my knowledge there were fourteen Type-I/J 2-PSI non-tapered tower sites:
TD3 field trial - "unitized" building/tower:
Alexander Arkansas - Main Station
West Helena Arkansas
Arkabutla Mississippi - Main Station
Cedarbrook-2 New Jersey
Mosley and Dunnigan have partial towers with horns mounted on outrigger platforms - which saved the expense of the large eight-horn main deck (41' square - you could park cars up there) supported by some rather complicated ironwork...
By the time L-L got around to building towers at the Stanfield and Ellisville underground, they decided to go with conventional Type-L towers - both of which required a custom reverse-taper base section to interface with the existing foundation piers - the two towers have "hips". As a further cost savings, the Stanfield tower has neither deck grating, safety railings, nor step-off rest platforms - which also dramatically reduced the temptation for 'exploratory' tower climbing and vandalism...
Cedarbrook-1 was a conventional repeater station with Type-A 2-deck tower and cinder-block building. The two sites are co-located about 500' apart: <http://binged.it/UjxrtM
Finksburg is the only 350' Type-J. Speculation on my part is that one of the reasons L-L put it up was to see what a full-height J-Tower looked like (they wouldn't do that, would they?) - wa -
