Formula for Attenuation

Inner Conductor
Outer Conductor
Dielectric
Ohms

Using this info only, because it's the bare minimum every manufacturer includes in their specification.
Could a mathmagician explain the formula for figuring attenuation in db per N ft at F frequency?

 

[wyShack]

Most manufacturers also supply db loss per 100 feet at various frequencies. The data is usually empirical. It would take much more that the info you list to calculate. along with the I^2*R losses 'in' the conductors you have leakage currents between the center and outer conductors-it would get rather involved to even calculate an estimate. I would guess that even things like the dielectric 'constant' of the materials would be in part frequency dependent.

Here is Beldin coax information guide. It's about 13 pages long and covers all their different coaxs.

As wyShack stated, you need more info than what you posted.
