Hello Jeff: I thought I had an old comprod catalog, but can't find it. However, I did have an old 1974 vintage Prodelin catalog. It had their line of Spir 0 foam coaxial cable listed.
It did have listed in it a very similar 1/2" type cable with a VF of 81%. Perhaps they made this cable for com products or vice versa. The VF for the 75 and 50 ohm cable of this size and 3/8" and 7/8" were also the same. Again, if you want me to fax the page out of this catalog, let me know. I'll bet the VF is 81% on that vintage cable. During that era, they all competed with the same spec cable. Ciao, 73, Tony, K3WX Jeff DePolo WN3A wrote: > T > Thanks for the offer Tony.
