I'd guess that the loss is a bit lower than AVA5, given the .91 VF and construction style. Spaced disc 75 ohm cable was popular in Cable TV distribution until plants ran up against the upper frequency limit of the cable, which was determined to be only 1 GHZ or so. The slight bulges in the shield at each disc, at precisely the same spacing, created a hard freq limit above which performance went to hell.

Other than that it's good cable.

Interestingly - none of Trilogy Coax's spec sheets are available?

What is the loss per 100ft of 7/8 inch hard line at 28Mhz?  For LDF5-50A its
0.19db.
