Many of these will have purpose made cable entry/ exit slots for the cable to enter and exit nicely.Īlternatively you could get a small IP56 or IP66 junction box typically used by electricians and electrical contractors and place your cable join in here. There are many types of purpose made external junction boxes on the market, including masthead models that can be cable tied directly onto aerial masts. The cable join can also be weatherproofed by placing this inside an externally mounted junction box.

Silicone grease is particularly helpful when doing TV aerial or satellite dish installations in seaside properties or marine environments when the water has a tendency of driving itself in all places. I would use a smear of silicone grease in this instance to be sure, I would even use it on weatherproof connectors and it helps preserve the exterior of the weatherproof plugs meaning that if you ever need to unscrew at a later date, it will easily undo. I would usually use this as LNB connections because even though LNB’s have a pull-down rainwater cover, this doesn’t always offer the most reliable protection and often the pull down cover doesn’t even fully cover all of the F plug itself. It’s not ideal for exposed joins where you should use self-amalgamating tape or an exterior junction box, but it is perfect for weatherproofing connectors at satellite LNB’s or inside TV aerial splitter boxes/ masthead amplifiers or other types of masthead equipment. One thing you could use for exterior coax joins is silicone grease. Personally, I always do two wraps, covering about an inch of the cable either end just to make sure. When wrapping the cable is flexible and easily extendable, you need to pull it to about twice it’s natural length when wrapping around the cable. It usually has aplastic strip on one side which needs to be removed and this needs to be the side that wraps around the join itself, so it’s on the inside not the outside. When you have connected the two pieces of coax cables together it wraps around the join to weatherproof. Self-amalgamating tape is what I would always use for outdoor TV aerial/ Sat/ Sky TV joins. This is usually only a quarter turn after you have finger tightened. The connector has internal O rings that are effective when the plug is fully tightened when you install, so you will need to tighten with a spanner(11mm) for this to be effective. I wouldn’t put this to the test mind and I would still try to wrap in self-amalgaming tape so offer further weatherproofing but this isn’t always possible are connections are LNB’s where the pull down cap prevents you from doing this. When installed correctly the join(supposedly) can be completely submerged in water and it will still be okay. There are multiple brands on the market but I use the Cablecon compression plugs for this task. These are usually compression type plugs which require a specialist tool to fit the plug to the cable. You can purchase F plugs that are designed for exterior use.

Please check out our video on how to do an F join. You will require two F plugs and one F coupler, often called a barrel connector. If you are going to join coax cables I recommend using F connectors for this as they are superior to standard coax IEC plugs. If you have multiple joins on a single cable you may want to consider replacing it but otherwise you will be fine. There are signal losses associated with coax joins but they are negligible. You need to make sure you have the correct sized coax connectors for the cable you wish to join and you fit them properly. You just have to make sure that this is done correct. Let’s begin.īefore we discuss the ways and means of how to join a coax cable, one of the most common things I get asked is can you actually do this? And the answer is yes, it’s an old wives tale that TV cables can’t be spliced. In this article I discuss the ways that you can weatherproof/ waterproof TV cables outside. Waterlogged coaxial cables are actually very common and heavily waterlogged cables can damage the TV equipment that they are connected to. If it does, you could get problems with your aerial or satellite TV reception. If you need to join a coax cable outdoors, special care and attention needs to be made to ensure that water cannot penetrate inside the cable.
