This stuff is great. I tell my wife how cool I think it is, and she says “What’s the big deal? It’s just tape…” Not just electrical tape. It’s self-amalgamating tape! Just the thing for us folks with antennas subject to wind, rain, and snow. Wrap it around those N connectors between my antenna and the LMR400 to my wireless network card, and feel safe that it’s a weather-tight seal.
I guess it’s also called Tommy Tape, or self-fusing tape. My neighbor turned me onto this stuff as he was investigating our 802.11b neighborhood WLAN. I haven’t found any really good pictures on the web of its use yet, but here’s one. And the first link has some instructions on how it’s used. Better yet, just Google it. Looks pretty ordinary, so I guess I see what she means. I just got my connectors wrapped up again after moving my antenna. All ready for the Spring rains.
