How To Ground A TV Antenna?
Grounding means to connect something with the earth. Mostly the metallic parts of the equipment are grounded so that the electric current in them is earthed and no harm is done by the metallic parts. The metallic parts in various equipment like antenna are joined with each other so that they form a circuit path for conduction of electric current.
The antenna is one of that equipment whose parts are made up of metals and connected to the rooftop of your house for the reception of electric or radio signals. The antenna is highly helpful as it gives you the best quality radio and electric signal, but at the same time, it can be your real danger to your house if it is not grounded properly.
If the antenna is not grounded, then in the case of lighting, it would allow the electric current to pass through it. This means that it would make a pathway for electric conduction of electric current through all the metallic equipment nearby or, worse, make the lightning current pass throughout your house.
But you can do the grounding process yourself very easily if you have the proper tools for it. It is a very simple process and does not need special tools. But in case you are inexpert with electric circuits and technical things, it is better to take the help of an electrician rather than doing it yourself.
There are certain codes for the grounding of the antenna. These codes differ with every region, so make sure that you are familiar with the rules and regulations and all the codes for the installation of a TV antenna at your place.
Tools And Equipment
First of all, you need and wire for grounding. It is better if those are copper wires because copper wires are much more durable than other metallic wires. Then you need some clamps to hold your wires together. They can be ground or pipe clamps; mostly steel clamps are used for this purpose.
Thirdly you would need a grounding block. It is used to ground the antenna cable. A standard grounding block is like a clamp. It is present near the place where the coaxial cable is installed in houses.
It dissipates the static charges from the cable, ensuring smooth signals. There are two holes in the grounding block from where the cable is attached to the side, and from the other side, the coaxial cable is grounded with the help of a grounding wire.
The fourth thing that you would need is a coaxial lightning catcher. If you feel that the lighting would directly strike your house, then it is better to get a coaxial lightning catcher rather than a grounding block.
Its working is quite interesting as there is gas filled in it which gets ionized by a high voltage current directly, making the path of current to the ground, saving your house and other metallic devices nearby from the lightning.
Ground clamps are used for grounding the wires and fitting them in the place properly. Split nuts are good for this purpose as they fit the wires in place really well. The last thing you need is required for the coaxial cable.
You can use any type of cable that you like but purchase it more than required to don't run out of the wire during the process.
Important Tips And Tricks
There are some points to keep in mind before you start the actual process of grounding the antenna. Once you have collected all the appropriate equipment for your task, there are few things that you need to make sure of before the installation process.
Step By Step Process
There are a few simple steps that you can follow to get your outdoor TV antenna grounded perfectly.
There is another shortcut method that you can adopt to ground your TV antenna in no time.
You should always use a thick copper wire for this purpose because you are making a long-term setting, so keep it is better to spend some money on buying a copper wire with a good diameter.
Also, use good quality nuts and bolts because an improperly grounded TV antenna can be a danger for you.
What Is The Process Of Grounding A TV Antenna Mast?
Grounding the TV antenna mast is an easy process as compared to grounding an outdoor TV antenna. For this purpose, you need to attach the coaxial cable with the help of a mast clamp and then attach it with a ground cable.
While attaching the ground wire to make sure that it is fixed in place with the help of a screw or a bolt and is in direct connection with the mount, if you are using matched grounding wire, then run it through the house grounding wire and then attach them. You can also attach it with the coaxial cable separately with the help of a nut or a bolt.
Types Of TV Antenna Grounding
Exclusively there are two methods for grounding external TV antenna. It can be a single point grounding or a single wire grounding. A single point grounding is simple as compared to a single wire grounding. Both of these are the same but with some minor differences in the attachment method.
In a single-point grounding, there are some local codes specified by the electric region department. In a single-point grounding, there are two types of ground wires. One is used to connect the antenna mast with the ground. The other wire is the coaxial cable which attaches the grounding block with the earth.
A single wire grounding, on the other hand, uses a single wire for connection purposes. It attaches the antenna mast passing the wire from the grounding box to the actual ground. The code used for connecting are international and specified by distant agencies but certified by regional electric departments.
The type or method for grounding a TV antenna that you should adopt highly depends upon your purpose, whether you want to access the regional or international codes.
What Is The Benefit Of Grounding A TV Antenna?
There are two main reasons why we ground a TV antenna. In case of a thunderstorm on lightning, your metal antenna can serve to be a source for conduction of electrical current throughout your house which can result in burning down off your entire house, which is something you don't want.
Moreover, proper grounding of the antenna makes your signal reception better, which helps the internal in its proper functioning.
Does An Indoor TV Antenna Need To Grounded?
An indoor TV antenna does not need to be grounded as it is actually grounded itself. There is no need to make an external grounding setting for the indoor antenna at all. Plus, there is no risk of lightning damage with your indoor antenna, so why would you spend money on the ground in it.
You can adopt any of these methods for grounding your TV antenna but if you have an ungrounded TV antenna, better get it grounded now for your safety.
