An indoor antenna is a type of radio or TV antenna placed indoors, as opposed to being mounted on the roof. They are usually considered a simple and cheap solution to receive transmissions. An indoor antenna is prone to picking up electrical noise, but digital broadcasts are resistant to this noise.
Indoor antennas are designed to be located on top of or next to the television set, but are ideally placed near a window in a room and as high up as possible for the best reception. [1] The most common types of indoor antennas are the dipole [2] ("rabbit ears"), which work best for VHF channels, and loop antennas, which work best for UHF. [3]
An antenna that is exactly isotropic is only a mathematical model, used as the base of comparison to calculate either the directivity or gain of real antennas. No real antenna can produce a perfectly isotropic radiation pattern, but the isotropic radiation pattern serves as a "worst possible case" reference for comparing the degree to which ...
At this point, it’s old news that cable has become all but obsolete in the age of streaming. With the dominance of streamers such as Hulu, Disney+ and Max, many people have dumped their ...
At the lower end of the spectrum, a portable radio with a larger-than-normal internal ferrite core antenna designed for long-distance AM radio reception may be used, such as the discontinued GE Superadio, CC Radio, or the Panasonic RF-2200. The Sony ICF-SW7600G and the newer GR model are also excellent for budget minded MW dxing.
In radio communication, used in radio and television broadcasting, cell phones, two-way radios, wireless networking, and satellite communication, among numerous other uses, radio waves are used to carry information across space from a transmitter to a receiver, by modulating the radio signal (impressing an information signal on the radio wave ...
Their impedance can be made relatively constant over a frequency range 4:1 or more, with the forward gain increasing at 6 dB per octave. Multiple rhombic antennas can be connected in an end-to-end fashion to form MUSA (Multiple Unit Steerable Antenna). MUSA arrays can receive long distance, short wave, horizontally polarized downcoming waves.
The bandwidth characteristics of a resonant antenna element can be characterized according to its Q where the resistance involved is the radiation resistance, which represents the emission of energy from the resonant antenna to free space. The Q of a narrow band antenna can be as high as 15.
