Re: Heatshrink

Hello all

Thanks for your helpful comments about heatshrink, on and off list.

Turns out, after some experimentation today, that it is pilot error -
although I'd prefer to blame my tools; My two setting heat gun has turned
itself into a single setting - the low one of course - and it is man enough
to shrink the material but not enough to get the glue flowing nicely.

Time for a bit of retail therapy !

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

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

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

Any recommendations for decent quality sticky heatshrink please ?
