If that's the case, why do all TV antenna installations use 75ohm coax?
===================================
Because it is much more convenient to install and easier to keep dry. And
TV receivers don't have 300-ohm antenna sockets.
===================================
No-one uses 300ohm feeder at UHF!
===================================
Except when engineering economics and the appreciably lower loss of 300-ohm
line is less expensive than providing and running a higher power
transmitting station.
