Impedance mismatches cause power loss. That matters if you are running 100,000 watts or even 25 watts but all I expect to be putting out is a couple of hundred milliwatts. Even if I use a 1/4 wave whip which has a nominal impedance of 50 ohms and the TV booster has an output impedance of 75 ohms the small mismatch and low power won't cause any trouble.
The C Crain transmitter has nothing but a short whip. I would have to open up the back, something I'm not afraid to do, and find the ground so I can take off a coaxial line to the booster. Regards.
