A high-gain antenna is an antenna which allows for precise targeting of radio signals due to it's use of a narrow radio wave beam. To use a high-gain antenna you should put attach it to a high, clear surface to allow it maximum range to receive and send radio signals. A good place would be the roof of your house.

Italian Space Agency provided the High Gain Antenna for the Cassini Space Probe. The HGA was built by Alenia Aerospazio.
You can buy high gain antenna's for your task at a number of online shopping sites, such as amazon.com. I would suggest going there to fulfill all of your needs.
There is a website called Antennahub.com that sells them. You may also want to check the place you brought your TV from. They will be able to tell you if you do need a high gain antenna and what will work with that TV
Snow is the unwanted noise in the TV signal. To overcome this you need a stronger signal from the transmitters. Increase the height of theTVantenna above the ground, use a larger high gain antenna and use a amplifier at the antenna with new high grade coaxial lead in wire. Be sure the antenna is aimed correctly. All of these changes will almost always give a better picture.Read more:How_do_you_eliminate_snow_out_of_TV

One way to boost the signal of a wireless antenna is to upgrade to a high-gain antenna. Other methods include adding a USB adapter with an additional external antenna or even to create a parabolic dish using a soda can.
increases by 6 dB
The size of an antenna depends upon the frequecny of the RF signal and the gain.
Some advantages of the Yagi- Uda Antenna include that this is a widely used design and low cost. The construction also is simple. Some disadvantages are that the receiver of the Yagi-Uda Antenna may have problem receiving signal.
