I have been an RF (radio frequency) radio broadcast engineer for 60 years.  I hold a General Class Radiotelephone License from the FCC.  I have served as Chief Engineer for a number of radio stations, most of them 'full power' facilities in major markets (Boston, Philadelphia)/.  Experience with the Radio Sprctrum ranges from the low end of the MW (AM Broadcast) band through the HF, VHF, UHF and 'microwave' bands.  I do not have hands on experience with the mobile, personal communications services.  The RF bands for these services are very high: Most well above 1 gHz (1 billion Hertz), ranging up yo 79 g
hz.  This very complicated allocation system is managed by the World Radio Conference.  Yes, high frequencies can be dangerous, BUT so can lower frequencies.  What counts is the POWER; you are not going to be climbing up and placing your body in front of that antenna, are you?  Even that is low - probaby less that 100 Watts.  In the field (where we hang out), the electrical field from that antenna is reduced to a tiny value.  The transmitter of the phone you are holding should be of more concern!  There are many studies/articles - Google.  Ordinarily we are immersed in dozens of radio fields wherever we are.  We have been in these fields for over 100 years,  No measurable damage  --  Ever.
