The RFS LCF78-50JA listed on his website is similar to Andrew LDF5 which 
has a smooth center conductor, and similar bending properties.

Both companies offer "superflex" and "ultraflex" varieties with 
corrugated center conductors. In 7/8" the RFS series is UCF78-50** and 
the Andrew is VXL5-50.

You pay a small attenuation penalty with the more flexible cables.
