|  | This black tape uses no glue and doesn't stick to anything but bonds to itself when stretched and overlapped. Getting the plastic backing off can be a pain so here's the secret: make a scissor cut halfway across the tape about 10 mm from the end (enough for you to get a grip of it). |
|  | Pull the tab thus formed and the plastic will peel away from the rubber so you can grip it with your fingernails or pliers. Easy when you know how! |
| Sealing Joints |
|  | See How to Fit an 'F' plug. It's important to seal outdoor joints against moisture. Squirt a tiny blob of silicone grease into each 'F' plug so the centre copper wire is coated. |
|  | Screw the two cables to the threaded barrel. Scrub off any silicone grease with a dry tissue. Cut a piece of self-amalgamating tape. 150 mm (6") is usually enough but, for a beginner, take 180 mm (7.2"). Peel the plastic backing off the rubber tape. |
|  | Hold the tape so its furthest edge is about 30mm from the 'F' plug. Stretch the tape and, while maintaining the tension, wrap it around the cable and joint with a 50% overlap so the tape sticks to itself. |
|  | Continue to stretch and wind until the joint is completely sealed, then reverse direction and cover the tape with another layer. Cut off any excess tape close to the cable while still maintaining the tension and press down hard on the end. |
| Sealing an LNB connection Note: modern UK Sky Minidish LNBs have a pull-down rain cover and don't need self-amalgamating tape. All they need is silicone grease inside each 'F' plug. |
|  | Hold the end of the tape against the cable, away from the "F" connector with one hand and stretch the tape with the other hand. The idea is to stretch it to twice its normal length as you turn it around the cable towards the LNB. |
|  | Continue to stretch and turn it until the "F" connector AND the exposed LNB connector thread is covered. Maintain that stretching tension all the time. Order page Warning: we recommend putting silicone grease inside the "F" plug to keep condensation out. But if you get grease on the tape IT WILL NOT BOND to itself. |
|  | Stretch and turn the tape back down the cable so it bonds to itself. Cut off any excess tape. Order page |
| Hi Martin, Reading your mention of silicone grease took me back to a radio programme I heard on the old BBC Radio London when Johnny Longdon was the engineer there and used to broadcast a technical session once a month. One broadcast dealt with rigging aerials and one of the BBC riggers recommended the plentiful use of silicone grease in all aerial connection boxes and connectors. I have followed the advice ever since, especially during my time as a licensed radio amateur, when I found a complete absence of corrosion in connections given the treatment and taken down after many years exposure to the elements. I find it especially useful these days when applied to F connectors under their boot. Kind regards, Jack Other uses for S-A tape Caravan/camping You can protect the cable from frequent handling by fitting a push-on adapter to the 'F' plug and binding it with tape to form a "handle". |
|  | Start the tape about 40mm from the plug. |
|  | Stretch and wind until the 'F' plug nut is covered then continue back down the cable. |
|  | Repeat until sufficient thickness is achieved. The result will be a flexible "handle" that will protect the cable. |
| Cycling |
|  | Apply the tape to bicycle handlebars to give an amazingly soft non-slip grip. If the tape feels a little sticky to begin with, apply talcum powder. Build up the layers to give you the exact grip that you need. Also works on shopping trolleys, wheelchairs etc. Order page |
| Walking |
|  | Apply the tape to walking sticks, umbrellas and anything else where you need a soft non-slip grip. It will never slip off (but you can remove it with a sharp knife). If the tape feels a little sticky to begin with, apply talcum powder. Build up the layers to give you the exact grip that you need. Order page |
