(Francisco Kjolseth | The Salt Lake Tribune) Robert Gehrke. | March 14, 2021, 12:00 p.m. It was about a year ago that a friend got an unwelcome surprise when — completely without warning — an ugly pole was plopped in front of his Salt Lake City home. It was the first 5G wireless tower I remember seeing. Since then, of course, they’ve sprouted up all over town to the frustration of residents who get to look out their window and see what amounts to a giant antenna, placed there without regard for views or neighborhood aesthetics. The problem will only get worse. That’s because while these towers can blast huge amounts of data to your cellphone or wireless devices — 100 times the 4G technology they’re replacing — they have a limited range with each tower only able to send its signal about 100 meters.
