Cant speak for wet weather but 300 ohm has less loss.
Thing is you gotta be careful running it near metal. It will also
pick up interference. When using coax you also have to go
from 300-75 at the antenna then back to 300 at the TV.
The transformers on both ends added more loss, a few db
but it adds up on a long run. We were 25-50 mi from our
UHF's with lots of hills & white pines killing the signal.
Some would even top a pine for a UHF antenna tower.
The Bruins & later the Sox were on U so it was a big deal pre cable.
At the time they were selling the old ribbon cable, foam lead
which we used, a round twin lead & shielded twin lead.
