Hell, someday they are going to put ADS-B transmitters ontop of
radio towers. It will happen.

There is already a system in existence that does a good job, and the FAA
has, or maybe still is, evaluated it. It was designed in Sweden, IIRC,
and
can be installed at any tower, wire crossing, or other obstacle, and
receives transponder transmissions, determines if an aircraft is likely to
hit the obstacle, and transmits a warning on all VHF frequencies. All
that
is required in the aircraft is a transponder and a VHF radio turned on.


Think about what will have to the airwaves when such a broadcast is made.

Better to have detection of the signal active an alarm in the subject
aircraft rather than broadcasting it to EVERYONE in the area.




Kinda like ADS-B. Hey, didn't we start there ?
