Hi Frank I use Raychem heatshrink with overlapped 3M self-amalgamating tape and finally Denso tape. I also have bright shiny connectors after a good number of years. Don't forget to wind the tape so that when it tries to unravel it tightens the connector. I am sure I'm not the only one who has seen that if you do it wrong it can unscrew the connectors. Not seen this happen for years but I have heard from other installers that it is quite common.

Denso tape is really the best thing for the job.

As someone who spent his working life installing professional communications aerials can I recommend you to Denso tape, It's the absolute best. A light Hessian tape seriously impregnated with a heavy wax. Inexpensive, and available in a range of widths from your local plumber's merchants or on line

I've spent part of today tidying up cables and repositioning masthead boxes on 23, 13 and 9cms. While doing this it became clear that I could make a better job of it by changing an angle N type to a straight one.

When I stripped back the glued heatshrink I discovered that it had not adhered to the cable (LDF4-50) at all, and it wasn't much better on the plug body. It wasn't an eBay cheapo buy, but it wasn't from Andrews/Commscope either.

Any recommendations for decent quality sticky heatshrink please ?
