 Radio Marti is now broadcasting in AM and DRM. Which one do you think Cubans are listening to and why?

The RF Workbench / 50 to 75 ohm 1/12 wavelength coaxial transformer
« on: December 23, 2019, 2156 UTC »
I have a VHF FM transmitter with a 50 ohm output. I want to make a 50 to 75 ohm 1/12 wavelength coaxial transformer so I can use 75 ohm coax to connect it to an antenna. I want to use F type compression connectors to join the coax sections together. I need some 50 ohm coax with most of the dimensions of RG6 (except the O.D. of the center conductor). Looking around I see RG5 and maybe LMR300. Looking some more I can't find a source for small quantities of either one. Does anyone know if LMR300 would be compatible wit F compression connectors and a source for RG5 or LMR300 by the foot?
