i use mainly dipole antennas

my understanding is that dipoles have a natural impedance near 75 ohms

radios and coax for amateur radio are 50 ohm

it is easy to find 75 ohm coax cable to TV

is there a solid reason why we don't use a 1.5:1 transformer at the 
radio output and use 75 ohm coax??

too much loss??

what is the loss of 75 ohm cable at UHF and VHF frequencies?

HF frequencies ??
