You might find some 75 ohm coax with wires as used in security/video/ 
ENG systems.

Belden 9265 is RG59 + a shielded twisted pair. 9165 has 3 pairs.

1dB/100ft loss at 10 MHz

There's also Belden CCTV cable RG6 + 18/2




For only 50 ft, I'd get some black heat shrink and use it to bundle your 
coax and control cable. something like a half inch of heat shrink every 
foot.

Or, depending on the environment, just spiral black tape the length of it.

Are you fixed on the AH4?  There are other remote tuners that can be 
powered/controlled via the coax.
