Well, the KFBK Franklin is two vertical 180 deg co-linear elements
center fed [in-phase, I think], so I guess it would be about 1,600 ft
[almost 500 m]. A couple of the TV towers in Walnut Grove down in the
Delta are 2,000 ft [600 m], but they're not center fed. [:-) I think
most "half-wave" BC verticals are close to but not exactly 180 deg.
IIRC, KFI [640 KHz] in Los Angeles has a 725 ft tower which is almost
exactly 180 deg but has a capacity hat that extends it to an effective
195 deg or so. When you drive by it on I-5, it is one very tall tower.

Yep, flamethrower of No. Cal. The groundwave coverage is amazing.
Imagine how big that thing would be if they were on 580 instead of 1530 :^)
