Yep.

Nope. The OD of the shield is too big to fit into a UG-176 reducer. FSJ1
is exactly a quarter inch OD without the jacket. LDF1 is 0.31". A UG-176
reducer is designed to fit over RG8X, RG59, et al which are typically 0.242"
OD. You can usually coerce the reducer onto FSJ1, but you'd have to drill
it out bigger to fit LDF1 into it.
