Jim,
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.
