MODERATORS
It's not that straight forward. And in a practical sense 162MHz is hardly significantly higher than 100MHz.
Apologies, I accidentally missed off the end of the quote, the bit I was commenting on:
I agree that it isn't much different. However it is objectively worse than regular FM radio, not better as the article claimed.
I still disagree. There are far more significant factors than the frequency.
Longer wavelength isn't an instant blanket solution to better propogation.
Factors like typical transmitter and receiver configurations matter, location matters, object density matters, reflections etc.. etc..
Hence why UHF is preferred in some cases by emergency services and so on.
Ultimately anything above 60MHz is going to be line of sight or a reflection when assuming the receiving station is mobile or portable, and in that case if the user is indoors higher frequencies might reflect better.
Also narrow FM has more power density than wide FM for the same power level, hence why broadcast transmitters need to be so incredibly powerful to get anywhere.
