Open inline type F low pass filter?

[Slickone]

Does anyone know how to succesfully open one of these, without damaging it?

Is it more than just a coil?

Should be able to figure out how it behaves, give or take, by looking up the frequencies of the channels it passes and blocks...

Good luck!! That looks exactly like the traps used by the cable company. Those things are impossible to open without damaging them. However, it is only a low pass filter, so the contents aren't exactly a mystery.
