Cable antennas have been around for years and have gradually become old technology. New Digital HDTV antennas together with a booster will allow you to watch your favorite cable television shows without having to pay for an ongoing cable subscription. A TV antenna booster will give you access to beautifully clear digital television shows for both standard analog and high definition TVs, and will catch all signals within approx.
You can eliminate the cable and associated subscription costs to enjoy clear reception and more television channels in the comfort of your home living room, or business office reception area.
Digital TVs have far better clarity and quality than analog TVs, but a weak signal often causes problems with reception. A weak analog signal will, for example, appear as a grainy or snowy picture on the TV screen. Although this is very annoying, the picture can still be seen or perceived. If a digital signal is slightly weak, it would however still be clear and sharp. With a digital signal that is too weak, the video and audio will cut in and out, or may even disappear altogether.
Another problem is multipath, where some of the TV signals bounces off structures like tall buildings and arrive slightly later than the signals on a direct path.
With an analog signal, this would cause a "ghost" image, which is a faint duplicate of the picture and slightly displaced. Once again, this is still viewable, albeit annoying. With a digital signal, the symptoms of multipath would be the same as a weak signal, i.
In simple terms, the number of channels you can access depends on the signals that are broadcast in your local area.
The reception quality depends on the physical distance from your local signal towers along with other factors including the weather, your surroundings, and the terrain. TV signal boosters, often also known as TV antenna amplifiers, help to improve the signal quality received by TVs in locations with distant or weak signals from a TV transmitter.
Signal boosters are often used with aerials on properties that have many obstructions around them like trees in rural places, tall buildings in urban environments, or in hilly locations. There're a number different types of TV signal boosters available on the market, each with their own purpose and application. These types of boosters are easily identifiable as they are small boxes which are installed close to a TV aerial, usually close to the base of the mast.
Masthead TV Amplifiers are the best option for signal boosting as they provide much better results than indoor and distribution boosters.
The signal is boosted as it passes through the aerial, and this improves the signal quality without needing a boost as it goes to the TV through the cables. Most amplifiers of this type are manufactured weatherproof and are therefore suitable for both outdoor and indoor use depending on the type of aerial fitted. This type of booster is normally used on properties with very poor signal strength. TV signal boosters need to be installed very close to the antenna.
That way, signals can travel along a cable without reducing its strength even if it is weak. The closeness to its background noise means that late bosting does not improve the noise level. In case you have the plan of cutting on using TV cable to save money, then you need an excellent antenna booster for watching the favorite shows.
When picking the best one you need to start by finding out the channels existing in your area. Once you get an idea of the stations you can watch then you have opportunity to select an antenna. Following your geographical area, opt for what brings many and high-quality channels. Before you rush to spend money, you can consider creating buying one that you can afford. A TV antenna booster provides more kick to a video system and brings an excellent video performance.
The functions include filtering noise levels and improving signal strengths. The device however comes useful when placed well. Installing your antenna booster starts when you chose where to run it on the TV cable. It is more logical to connect to both the input and output close to the television.

A Lot Of Signal The math here is simple folks: There is such a thing as amplifying the signal too much.
Massive Overlooks You should never forget that the booster needs electricity or current to run. Filtering Problems Channels are usually separated by differences in signal. A good quality coaxial cable should only lose around to 1db If you are losing more than this, you should look at replacing your connecting downlead, wall plates and fly-leads which could explain the signal losses. This would be a perfect time to introduce a TV aerial amplifier.
Here are the associated losses with good quality passive signal splitters on frequencies used by TV and Freeview UHF - Mhz Please note that there are other factors that could affect how much signal you lose in a splitter, like quality of the splitter and temperature:.
When doing your calculations, it is always best to err on the side of caution, so I recommend adding a few dB to each of these losses so you have a little room for movement on your signal levels. Here is another scenario with a splitter introduced.
If you would like to know more about how many TV's can you feed off a single TV aerial please click the link below. The introduction of an 8-way splitter to feed the amount of TV points required was directly responsible for the weak TV signal which would most likely result in poor TV reception. Done the correct way. A stage of amplification has been added before the signal losses associated with the 8-way splitter. This has overcome it completely and there is more signal gain on the amplifier than there are signal losses on splitter.
As a result, the TV now has more than enough signal to offer a good reliable reception. There are amplifiers widely available which provide both the signal splitting and amplifying operations.
These are called distribution amplifiers. It would typically create a neater installation. One of the obvious drawbacks of installing a TV aerial amplifier is that a power supply will be needed near the aerial. This is fine where there is a mains electrical point in the loft as it is only typically a short length of coaxial cable that would connect an amplifier in a loft to a aerial on a chimney, or a aerial on a wall.
The aerial itself may even be in the loft. In which case this would be perfect. However, it is not typically common to have a mains power socket with a loft.
In which case, you contact a local electrician to come and install one for you which would obviously cost you more money. A more suitable option though and one the TV aerial installer could do for you and without the need for a qualified electrician is to install a line powered amplifier instead of a mains amplifier.
A small power supply unit or PSU is installed onto the aerial cable and a DC voltage, usually 5VV is sent up to the masthead amplifier on the coaxial cable allowing it to boost the signal. The benefits of a masthead amplifier over a traditional mains amplifier is no mains power is required at the amplifier position, the masthead amplifier itself can be sited very close to the aerial itself, most common on the aerial mast and comes in a weatherproof outside box, hence the name.
This allows the signal to be amplified whilst it is still at its strongest carrying the maximum amount of genuine signal throughout your TV systems. Here is a video guide on how to install a masthead amplifier.
