[TowerTalk] Protecting ferrites?

[Jim Miller]

I'm putting a string of 31 mix ferrites on some Buryflex at my feedpoint.
What's the recommendation for wx shielding?

I was concerned that ice might find it's way to crack them.

I was thinking of wrapping them with the rubbery 3m tape stuff followed by
3M 33 tape much like connector sealing.

Good, bad, unnecessary, insufficient?

Recommendations desired.

Thanks
