I heard from a cell service technician that most cell towers antennas are not really designed to radiate upwards. This kind of makes sense when you think about it, radiating up would be wasted energy.
This was in the context of asking why service/signal was so bad on top of a hill. I was thinking it would have been better because of clear LoS but that only makes sense if you assume an onmidirectional pattern.
- stygiansonic 5y agoMore info here: “It has a flat fan-shaped radiation pattern, which is tilted slightly down to cover the cell area without radiating at higher angles into further off cells which reuse the same frequencies. The elevation angle of the antenna must be carefully adjusted, so the beam covers the entire cell without radiating too far.” https://en.wikipedia.org/wiki/Cell_site https://en.wikipedia.org/wiki/Cell_site Also some antenna radiation patterns here, not sure how accurate: https://www.slideshare.net/nehakumar01/radiation-pattern-of-a-cell-tower-antenna-7938434 https://www.slideshare.net/nehakumar01/radiation-pattern-of-...
