            What are the factors to consider when buying a cable signal booster?

  • When buying a cable signal booster, consider whether it’s for internal or external use. Most boosters are made for internal use. For an eternal booster, the power is transferred via antenna coax cable from the TV. Your external booster should be waterproof and withstands harsh weather conditions.
  • A cable signal booster should not have too much gain. Gain is the level the booster increases signal strength and is usually measured in decibels, dB. 10 to 12 dB is the best standard quality. Your TV when fed with too much gain results to TV input overload and lead to a worse signal than the original.
  • The compatible abilities of the cable signal booster with your television. When buying the booster, it is advisable to check whether it will serve your TV perfectly by being compatible with it. The right booster will enhance the signal strength to your wish.
  • You should consider the purpose of the booster. It can be either domestic or for commercial purposes. The larger the area to serve, the larger the signal boost in dB the booster should have.
  • Some boosters come with other functions like VoIP and modem services. Always consider buying a signal booster that has an additional advantage for you.

      How to install a cable signal booster by yourself

cable signal booster


  • The first step is to find the best signal outside your house. The most crucial step in installing is locating the side of your house with the best signal. Signal strength can be achieved by your phone, using the number of bars on it.
  • Install the antenna where you achieved the best signal. Place the antenna the highest point of your house, the roof being the most ideal. Also, you can mount it on a mounting pole when still on the roof. The antenna should face away from the house to the nearest cell tower.
  • After mounting the antenna, connect a coaxial cable and run it to your house. You can run it into the attic or window entry point. The coaxial cable is to connect to the amplifier which should be in a well-ventilated area.
  • You know which place in your house requires a signal the most and place an inside antenna near that area. Run the included cable to the amplifier. There should be a 20 feet vertical and 50 feet horizontal distance to prevent oscillation between the inside and outside antenna.
  • The final step is to power the amplifier. After turning on, green lights indicate perfect working.

How can I boost my cable signal?

cable signal booster

A weak cable TV transmission is often an indication of a much deeper problem. And with the premium price for cable TV, a weak signal isn’t encouraging at all. The good news is that there are some ways to solve the problem of weak signals without breaking the bank. However, because not all weak signals have the same causes, it isn’t a universal fix.

Get an Aerial or Fix It Properly

Traditionally, you will install an antenna on your rooftop before getting TV. Improvements in technology, however, let you get your TV transmissions from a smaller indoor antenna. If you’re getting a weak TV signal, your antenna (indoor or aerial) either isn’t enough or adequately positioned.

Your aerial should stand at the tallest point of the house (usually the chimney). It’s a dedicated receiver that will make the most of the smallest signal to which you can get access.

Install an Amplifier

Get a signal booster for your cable TV if your weak signal persists even with an antenna. It improves the performance of your antenna and lets you squeeze out every single transmission from it. It’s also useful when using multiple TVs with the same aerial by preserving your signal quality across them.

Align Your Aerial Properly

If you don’t align your aerial correctly, you won’t get the best signal it could give you. It’s especially easy to do if you have a TV spectrum analyzer. It won’t matter how suitable your aerial is if it isn’t facing the right direction at the right angle. You can get a professional company to fix it for you cheaply if you can’t do it yourself.

Remove Your Splitters

If you aren’t using a TV distributor to split your signal, remove it. Passive splitters don’t account for your signal strength while working and may give you weak signals. Most passive splitters will cause you to lose between six to 12db signal.

Get Better Cables

Not all cables are suitable for transmitting to your TV. A right coaxial cable has significant EMI and RMI protection, and even better transmission. It will prevent you from losing too much signal to interference. Something like HD100 and CT100 ensures you get precisely the signal quality of your aerial records.

Use the Best Transmitter

Some transmitters provide better signal quality than others. Ensure your aerial is receiving from the most potent transmitter around you. Also, check regularly to ensure the transmitter’s signal quality hasn’t degraded.

Do TV signal boosters work?

The primary function of a cable signal booster is to improve the quality of your TV reception. However, the numerous models and types on the market don’t all work in the same way. Typically, your TV should be able to access all broadcast channels within your locale. But certain factors like distance and terrain mean that it isn’t always so.

What Is A Cable Signal Booster?

Cable signal amplifiers are a mix of boxes and aerials that can improve your TV signal reception. It’s like buying a better antenna for your TV. The best way to use your signal booster is to plug its input directly to your aerial’s output.

Also, TV amplifiers are not a magic solution to all your cable signal issues. A signal amplifier can only strengthen the signal you already have despite popular belief. If you can’t get a transmission at all, a signal booster is not the solution to your cable problems.

Signal boosters can take the form of antennas and small boxes. It fishes out background noise from your sparse signals and boosts your antennas reach. TV amplifiers may also increase your aerial’s sensitivity to cable signals, allowing it to pick up more of them. Boosters will also enable you to get around obstructions and resolve your images and sound into more definite forms.

Common Cable Signal Booster Types

Three main types of amplifiers can improve your TV signal quality. Whichever one you choose should depend on your budget and preference.

Masthead Amplifiers

A masthead cable signal booster resembles a small box and is very easy to use. You should install it just below your aerial for the best output but can put it anywhere you like. It provides the best signal boosting result compared to your other options.

Masthead boosters improve your signal quality as it moves through the mast, before getting to your TV. It can serve both indoor or outdoor and is usually waterproof and durable with UV-protection. This type of amplifier is the best for county homes with excessively poor signal quality.

TV Distribution Booster

One of the reasons you’re getting a weak connection may also be because you’re using too many TVs. There’s only so much broadcast to go around when your five TVs are eating it all up. Purchasing a TV distribution amplifier is a popular workaround to the problem, especially for Sky users.

It splits your cable signal in however many ways you want it. It’s significantly better than an aerial splitter because there’s no loss in signal quality. By connecting all your TVs to the distribution booster, you get the same signal quality on all of them.

Indoor Aerial Amplifier

It’s similar to a masthead booster as both of them are installed close to an aerial. You should install indoor amplifiers close to the TV instead. However, you can get even better performance from the booster if you install it close to an aerial. No matter how well an indoor amplifier functions, though, an aerial or mix of both is a better choice.

What Causes Weak Cable Signal?

Cable Signal

Sometimes, your TV starts pixelating and breaking up so bad that you just want to break it. It’s especially annoying if it happens when you’re watching your favorite shows. There are plenty of reasons why this may be happening, but the most prevalent cause is weak signals. For the most part, this problem is either a hardware (cable and equipment) error or a broadcast (signal) one.

Old Antenna

Unlike the old analog antennas, the new digital antennas perform significantly better. The aerials filter out interference and prevent data corruption, thereby allowing an unbroken signal transfer. So, your cable reception may not be the best if you’re still using an analog antenna.


As with all other waves, TV signals travel in straight lines and bend around obstructions. Hills, trees, residences, and similar can obstruct your cable signal strength and quality. It’s notably worse of your location is directly behind one of these things.

It breaks up, reflects, refracts, and bounce your signals. All these effects will affect the coherence and quality of your signal, distorting what you finally get. Obstructions are one of the most significant sources of weak cable signals everywhere.


The second most common reason for weak signal strength is cabling issues. Using an analog cable for a digital connection won’t give you the signal quality you should get. Most old cables lack any form of EMI and RMI protection that’s common in new ones. It makes them vulnerable to electrical interference, which reduces signal quality.

Older cables also have smaller sizes, which can only transmit smaller data packets at a time. Some wires are even too long because the longer your cable, the weaker the transmission quality.

Other cables are frayed and open, which can cause significant data packet loss. All the above issues are common causes of weak TV transmission signals.


Strong winds, high pressures, increasing humidity, and lightning are some weather conditions that can tank your cable signal. It acts as both a physical obstacle and a technical one. The high winds move your aerials and that of the transmission tower around.

It also blows dust and other materials into the air to physically intercept your signals. Rain does something similar by creating water mirrors to reflect your transmission midair. Lightning, on the other hand, generates massive EMIs for your TV.

Summer days are no better as the warm air creates a reflection for your TV transmissions. It can cause overlapping and destructive interference from multiple signals.

Multiple TVs

Using more than one TV on the same signal without a cable signal booster can weaken your signal quality. The transmission will get split in more than one way, thinning out and losing some coherency.

Mobile Interference

As internet use increases, the frequency bands for internet services also increase. ISPs now allocate internet frequencies close to those for cable TVs. It usually isn’t a problem for newer television devices because they come with filters for such things.

However, older TVs without filters may have problems distinguishing between mobile networks and cable. It’s even worse with 4G because they are sometimes more potent than your TV signal.

The 4G signal may overwhelm it and cause corruption in your reception. If your TV signal starts reducing when a new Telco mast shows up, you know this is your problem.

Wrong Antenna Choice

Not all antennas work for all broadcasts, location, or frequency. If you’re using a VHF antenna for a UHF transmission, you’ll get weak signals or none at all. The type of antenna you buy should depend on what your local transmitter uses.

Outside Interference

This type of interference can range from an amateur radio setup causing RMIs to police. Most cable TV is susceptible to interference from other radio equipment that lacks proper frequency protection.

Physical Damage

Your Actual TV may also have damage to its components. If your antenna is damaged, then you may get no or weak signals. The story will be the same if any integrated transmitting component gets broken.

How do you fix a weak cable signal?

cable signal booster

Before you rush to get a cable signal booster, you should first try to see if it could be a local problem. Not all weak signal issue is due to a bad antenna and transmitter. Some of the possible problems can originate from your TV, antenna, or cable. Here’s how to troubleshoot a weak signal.

Wiring and Hardware

The first step is to check if the problem is in your wiring and hardware before checking the signal itself.

  • Check for knots and bends on your cables. Look for any nick, cut, or leak in the wires.
  • Check for loose connections and frayed cables. Tighten your connectors, ensure they aren’t damaged and are right for the TV.
  • Gauge the signal from your aerial and see if you’re experiencing any signal loss. If the transmission on your TV is lower than on the gauge, your signal loss is from a wire somewhere.
  • Rearrange the cables to avoid other electrical wiring and devices, and radio equipment.
  • Disconnect all your splitters and check if the signal quality improves.

If all these steps don’t solve the problem, then the signal itself likely has a problem.


  • Purchase and install a signal amplifier and see if the signal improves.
  • Get an outdoor aerial if you were using an indoor one before.
  • Reposition your aerial towards a different transmitter.
  • Ensure it’s not a weather obstruction from hot or wet days.
  • Raise the height of your aerial to avoid buildings, trees, and other obstructions.

Between the five steps above, one of them should fix your weak signal issue.

The type of signal amplifier you should get should depend on the result of your troubleshooting. You shouldn’t be using TV distributors to fix your weak signal when you’re using only one TV at home. Cable signal boosters work and remain one of the quickest ways to resolve weak signals on cable TV.
