If you have a satellite dish mounted to the roof or the side of your house, it is able to be used as an external television antenna. This will allow you to receive digital broadcast television signals that are available in your area. Reattach the antenna to the back notch on the mounting clamp.
A mast or antenna-mounted amplifier (preamp) is used primarily to overcome the loss in the coaxial cable between the antenna and the TV set. In areas close to TV transmitters, a preamplifier is usually not needed, and can actually cause problems as it may cause the signal levels to be too high.

Here are some tips for boosting a digital TV signal:
- Move the antenna to new location or height, if you're using an indoor antenna.
- Re-aim the antenna, if you're using an outdoor antenna.
- Watch the signal strength meter on the digital-to-analog converter box or television as you move or aim the antenna.
If you're not getting any channels or absolutely no picture, a booster generally won't do a thing. If you're using an amplifier to distribute a signal over a long run of cable, or to multiple TVs, then make sure you use a masthead aerial amplifier.
Why might you want to install a masthead amplifier? You may need to amplify a signal in a place that doesn't have mains power, obviously it's great if you have a mains point in a loft but that isn't usually the case and you almost certainly won't have a mains point outside such as on walls and the aerial mast itself.
Here are my hints and tips to help you get the most channels with your indoor antenna.
- Experiment with Different Locations in Your Home.
- Use a Longer Cable To Reach That Window.
- Face it Towards the TV Transmitter Towers.
- Lay Your Antenna Flat Horizontally.
- Move it Higher Up (Highly Recommended)
Antenna amplifiers send a low-level electrical signal through the the coaxial cable leading to your TV. An antenna amplifier may connected as a pre-amp on the main external antenna or in conjunction with a coaxial cable splitter. You may use two or more TV amplifiers to boost the signal in your home.
Direction to aim the TV antenna. To aim all of our antennas, face the front of the antenna in the direction the channels are broadcast from. You can find this information by going to TVFOOL. It will show you the compass orientation and direction the channels are broadcast from.
If there are more than four outlets, and/or the cable length from the antenna to the distribution amplifier input is 50 feet or longer, and the cable length from the distribution amplifier to the TV set are 25 feet or longer, a distribution amplifier will probably be needed.
Cable modems will generally work with a splitter or a bi-directional amplifier. If you are not experiencing issues, and/or you are not sure what your signal strength is, you do not need an amplifier for it. Cable amplifiers not only amplify the signal, but also any noise on the line, and introduce some return loss.
Interference. Large trees can interfere with TV antenna reception. Indoor antennas in particular might struggle if near tall, bushy trees, according to the government's DTV website. Tall structures such as trees interfere with the signal by obstructing the signal waves or reflecting them off their foliage.
In electronics, an antenna amplifier (also: aerial eamplifier (booster), Am antennefier) is a device that amplifies an antenna signal, usually into an output with the same impedance as the input impedance. An antenna amplifier boosts a radio signal considerably for devices that receive radio waves.
Install the signal booster. Step 1: Select an indoor location near to a power outlet on a wall. Step 2: Mount the booster with the screws included as shown in your user guide or installation manual. Step 3: Connect outdoor antenna cables to booster connector marked "outdoor".
An old TV antenna may be able to pick up some of those low bands (wireless telephony also operates in 1800–2000MHz, as well as 2500MHz, among other). Every antenna will receive all signals but it is the design of the antenna that dictates how much signal is recoverable at any particular frequency or band.

It doesn't always improve but aluminum foil is a conductor and at radio wave's frequencies it is a good mirror. If the antenna can't see the transmitter because of blockage the foil might mirror it into line of sight. Another reason: a foil can block interference from unwanted transmitters.
How to Make a Simple Antenna to Improve the Reception of an FM Radio Receiver
- Measure 28-3/4 inches from one end of your wire. Wrap several turns of electrical tape at that point.
- Split the wire from the end to the tape.
- Attach each exposed end to one of two screw terminals on your receiver marked for the FM antenna.
One of the most common causes of poor car radio reception is a poor antenna connection. If the antenna cable is poorly seated in your head unit, or any of the connections are loose, worn, or corroded, you'll often find it difficult to tune into your favorite station.
The signal quality increases because your body is an antenna. You increase the radio antenna length and hence it's “gain” when you touch it. This effect doesn't happen at all frequencies and the increase in gain is fairly small. Your body is picking up the power line frequency like an antenna.
The Labgear KIT125V masthead TV amplifier is the best way to improve TV reception in poor reception areas, where a roof-mounted high gain TV aerial has failed to provide reliable Freeview reception.
Minimum signal can vary from as high as -55 dBm for a TV with poor sensitivity in a noisy environment, to as low as -75 dBm for a TV with good sensitivity in a low or no noise environment. Most televisions and conditions will require a signal level of at least -65 dBm.
- Step 1 - Assemble the VHF/UHF Masthead Amplifier. Take an assembled UHF and an assembled VHF aerial.
- Step 2 - Connect the Power Unit.
- Step 3 - Connect the Power Unit and Masthead amplifier. In the attic put an f-type connector on the cable from the power unit and from the Masthead amplifier.
TV aerial amplifiers work on the simple process that you insert a signal into an input and a stronger signal will leave out of the output, or a signal that is less weak than it otherwise would be for when your aerial amplifier also provides signal splitting facility – for multiple TV's.
An antenna itself is just a metal stick. It doesn't need power to function. What an antenna is doing is actually receiving a broadcast from the air and converting that broadcast into a very weak electrical signal that flows through the antenna and into the cable.
How does a masthead amplifier work? A masthead amplifier is an active device which requires power to operate. It takes an aerial signal in and then sends the signal out at a higher level. The amplifier itself is powered via the coaxial cable that feeds the TV by a power supply unit.
