Another technique is to use a half wavelength or integral multiple of  
half wavelengths of the 75 Ohm coax. A half wavelength transmission  
line will repeat the impedance at one end to the other. So if you  
connect 75 Ohm coax to a 50 Ohm load and feed it with a 50 Ohm  
generator, the generator will see a 50 Ohm match.

Also, RG-6 designed for TV and video use is widely available, low  
loss, and cheap. One can use these techniques to effectively utilize  
it.  - Duffey
