If you live in an area without cable TV or if you're on a tight budget and you still want TV for free, you'll need a TV antenna. Modern antennas let you receive both analog signals and digital signals, which most TV stations now use. Outdoor antennas are larger and can pick up weaker signals from farther away, making them the best choice if you live further than 25 miles from a TV station tower or if there are obstacles between you and the signal source.

Indoor antennas are smaller and easier to install and adjust. They're good choices if you live in an urban area, the nearest TV tower is less than 25 miles away and you're close to a strong signal without interference from trees, hills and tall buildings.

Another decision to make is whether to get a directional or a nondirectional antenna. A directional antenna receives signals that come from a specific direction, so it will work if you live in an area where most or all local TV affiliates broadcast from a shared cluster of towers.

If the signals you want to receive come from different locations, you'll need a multidirectional or omnidirectional antenna. This type of antenna can receive signals equally from all directions, though with less power.

TV antennas might seem like a relic of a bygone era, when the number of channels you received could be counted on one hand. Consumer Reports just finished testing a group of indoor HDTV antennas in all shapes and sizes in urban and suburban homes, and found that most of these locations were able to receive dozens of free over-the-air channels.

An indoor HDTV antenna can help fill that gap. We included some amplified HDTV antennas in our review.


They can sometimes help pull in more distant stations. Before you buy a new TV, check our buying guide and ratings of more than models from all the major brands.

Most locations were within a mile radius of Manhattan, but one was 70 miles away. We tested antennas near a window and away from a window, near the TV.

Back in the analog TV signal days, most major broadcast channels—say, 2 through 13—were in the lower-frequency VHF band. Now, they're scattered across both bands, so it's important to buy an antenna that does well across the board. Sign In. Become a Member. Remember Me. Not a member? Need further assistance?

In receptionan antenna intercepts some of the power of a radio wave in order to produce an electric current at its terminals, that is applied to a receiver to be amplified. Antennas are essential components of all radio equipment. An antenna is an array of conductors elementselectrically connected to the receiver or transmitter.


An antenna may include components not connected to the transmitter, parabolic reflectorshornsor parasitic elementswhich serve to direct the radio waves into a beam or other desired radiation pattern. The first antennas were built in by German physicist Heinrich Hertz in his pioneering experiments to prove the existence of waves predicted by the electromagnetic theory of James Clerk Maxwell.

Hertz placed dipole antennas at the focal point of parabolic reflectors for both transmitting and receiving. The words antenna and aerial are used interchangeably. The origin of the word antenna relative to wireless apparatus is attributed to Italian radio pioneer Guglielmo Marconi. In the summer ofMarconi began testing his wireless system outdoors on his father's estate near Bologna and soon began to experiment with long wire "aerials" suspended from a pole.

Because of his prominence, Marconi's use of the word antenna spread among wireless researchers and enthusiasts, and later to the general public. Antenna may refer broadly to an entire assembly including support structure, enclosure if anyetc.

The 7 Best TV Antennas of 2020

A receiving antenna may include not only the passive metal receiving elements, but also an integrated preamplifier or mixerespecially at and above microwave frequencies. Antennas are required by any radio receiver or transmitter to couple its electrical connection to the electromagnetic field. Antennas can be classified as omnidirectionalradiating energy approximately equally in all directions, or directionalwhere energy radiates more along one direction than others.

Antennas are reciprocal, so the same effect occurs for reception of radio waves. A completely uniform omnidirectional antenna is not physically possible. Some antenna types have a uniform radiation pattern in the horizontal plane, but send little energy upward or downward. A "directional" antenna usually is intended to maximize its coupling to the electromagnetic field in the direction of the other station.

A vertical antenna or whip antenna radiates in all directions horizontally, but sends less energy upward or downward. Similarly, a dipole antenna oriented horizontally sends little energy in direction vectors parallel to the conductor; this region is called the antenna null.

The dipole antenna, which is the basis for most antenna designs, is a balanced component, with equal but opposite voltages and currents applied at its two terminals. The vertical antenna is a monopole antenna, not balanced with respect to ground. The ground or any large conductive surface plays the role of the second conductor of a dipole.

Since monopole antennas rely on a conductive surface, they may be mounted with a ground plane to approximate the effect of being mounted on the Earth's surface.Here at Walmart.
