  tower has a very specific meaning in osm reflected by the icon used in the osm-carto rendering, as a concrete structure (see the stuttgarter fernsehturm, or actually both towers).  as i understand it, while i see three towers within an eyeful, this construct is absent in north america apart from the cn tower in what by now must certainly be an enemy land, but such structures across the pond are now commonplace.
  
  i would actually have to climb a hundred metres up to have a view of as many masts (lattice construction) as towers in the valley.
  
  good call on ukw; where i attempt to throw your FM as a modulation protocol available anywhere across the band, you have tossed the bandwidth of ultra-klein-welle against the common use of the 87,5 to 108 MHz frequency-modulated 50 usec pre-emphasis that i attempted to imply :-)
  
  but the fundamental whatever holds -- higher frequencies need a line-of-sight and antenna structures in human dimensions, as would be clear if i provided a link to photos of the swiss St Chrischona tower.
  
  the use of am as a modulation technique fails in the case of 108+ MHz, which maybe 50 years ago was air traffic control but definitely not frequency modulated.  i dunno know if things have changed in the intermediate decades to replace the robust and simple amplitude modulation at VHF frequencies with something else, but i remember tuning my ancient FM/VHF receiver to the top of its range to spy on one side of incoming air traffic thanks to its AM/FM ambiguity.  and laughing at what i heard.  times have changed.
  
  DigitalGlobe Vivid is an imagery layer that appeared within hours of the time i investigated this area, and resolves to e7252.dscb.akamaiedge.net as a pair of IPv6 addresses.
  
  there is no benefit from this additional imagery layer in this location, and for an osm mention of this, i refer to https://forum.openstreetmap.org/viewtopic.php?pid=748586#p748586 (german).
  
  the clarity area being best here means you have decade-old data, but i
