Yep-
We
look at Hamfests for any inductor with a "big hole" and pass the Ethernet or
COAX through with as many turns as we can cram in the hole.

DigiKey lists a standard inductance for each core and the frequencies they
filter. Its been awhile since I researched them, but my primary focus was
the FM interference and my secondary was just to get as much inductance as
possible for lightning suppression. - the more times you loop the cable
through it, the greater the inductance. I go for as many loops as I can
possibly get. A lot of times, I buy the inductor mostly based an the
physical size that will work for my application. I use them on just about
everything, even my RF pig-tails (with no looping).

How do you compute the total amount of inductance? Based on the length/properties of the Cat5 alone? Would you mind posting the formula or, better, a spreadsheet like that posted for solar?
