[aprssig] bad PHG, or lots of big towers?

[Jason Winningham]

Looking through the data Bob posted I find 46 digis with advertised 
heights of 5120ft (a mile!) and 140 with heights of 2560 ft.

Are there 186 towers over half a mile high with digis on them?  Are 
there even 186 towers over half a mile high in the world?

Or are there a bunch of operators who don't know the difference between 
height and altitude?

OK, the last one was rhetorical, but the first two were serious: are 
there really that many tall towers around?
