DLA Probe Cross Talk

I have a DLA probe that has a large standing wave. I am able to isolate the area of the insulator which is causing the issue, wondering if anyone has any experience in correcting/repairing the insulator?

Looking for suggestions on what materials (if any) I could use to re-insulate the damaged section.

The manufacturer of wedges should be responsible for this problem. If you are making your own DLA wedges, you could use silicone sponge gaskets that has adhesive on both surface.

Thanks Ali

The probes are not new, they have been refinished as the wear face had become dished from repeated use. I realize the probe manufacturer should/could correct the issue, I was looking for an in house fix.

I will look into the silicone sponge gaskets.
