What makes a TV antenna be 300 ohms? What makes coaxial cable be 75 ohms?

I read online 300 ohms was chosen because there are fewer losses. That must mean the design of the antenna makes it 300 ohms?

I read online there are few loses in coax cable so 75 ohms works fine.

300 ohms is 4 times more than 75 why is there fewer looses in 4 times more resistance?

I don't understand what I read?
