The transition from analog to digital really hurt my desire to watch OTA TV (you caught me! I'm not under 25).
With analog broadcast, any weak signal or interference produced a little bit of static, but you could still see and hear what was being said. With digital, any weak signal means dropped frames and silence or weird glitches. You completely lose what's happening. Even with a powered antenna, I have frequent issues with weak signal. I could probably try to get a rooftop antenna installed, but there's no guarantee it would be any better. It's just easier to find other entertainment at this point.
Ditto. We went from having five channels, one snowy on a bad day, plus a bonus 6th channel when the stars aligned, to two channels at best.
The broadcasters and regulators took a basic fact about digital signals "We can get a better quality signal with less transmission power" and saw it as a challenge to set up their digital transmitters with the most conservative estimate of minimum power required. I haven't studied well enough for my amateur radio exam to know if I'm comparing apples to oranges, but I'm still shocked to see descriptions of transmitter power go from 100kW in one case to below 20kW.
I hear that. We have an attic yagi aimed directly at Seattle from 10 miles away, and we still get the occasional dropout even on our strongest signals.
Still when it works, it works really well. We watch Nature and Nova on Sundays, and the wildlife footage looks incredible.
The switch to UHF is also a factor. Compared to VHF, UHF is much more susceptible to blockage by things like leaves. I live in a forest, and 70cm is basically useless while 2m is unaffected and I can work the nation on 6m.
I'm 26+ miles away from the broadcast antennas as the crow flies and I get great reception from an approx $100 antenna mounted in my attic. Some HOAs don't allow antennas and people might be surprised to learn how good your reception can be from an attic.
I guarantee a large rooftop a antenna would out perform anything you have indoors or those terrible small ones. The one you linked is way too small to work properly for the wavelengths used by TV stations.
