... My thinking is that I want something with 100 mile range, HDTV and 4K. Is there anything else that I should want in an antenna? ...
Eddie, even a coat-hanger is all those things starting the day you get a local broadcast signal sent in 4K, and is possible because of the higher digital vs analog content encoded within the carrier signal/channel/frequency/bandwith. (channel 'X' is 'xx MHz'
everywhere.)
The antenna is tuned to the channel's carrier frequency and only that, not the encoded sound and video data within it. Consider range capability by true (not just ad buzz) 'gain in db'. Fancy looks are usually just that.
Difference matters whether you need VHF (30" elements) or UHF (loops, 'bowties') or both channel frequency ranges to get all your channels. For VHF range you want many elements, as with the 'directors' often placed in front of a bowtie. 'Ganged' bowties can be less sensitive to precise aim, so may cover a city well vs just one channel.
I've put in a few of these with great results over several years now.

It just ain't me watchin'.

Gave it up in the '70s when cable's promised affordable (any of 'em now!!)
ad-free programming obviously was never going to happen. We have to pay to watch ads? Go ahead. NPR for news and weather, so I get to move about and use my eyes
for me all day.
IMO, the 'Digital and 4K' buzz-word hype is just that. (Digital nitrogen!)
