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.
