What type of antenna is used in cellphone for FM?

LNA - Low Noise Amplifier


What is the time for the TV signal to come from the TV mast to your TV set?

The signal will move down the cable at from about 1/3 the speed of light to about 9/10 the speed of light, depending on the type of cable used. If there is a booster amplifier in the cable between the antenna and the TV set this will add more delay. You will need to know the length and types of cable used (and look up their signal propagation speed) as well as the delay of your booster amplifier if your system has one to calculate the answer to your question.


What is detection antenna housing called?

The housing used for a detection antenna is called a radome. This type of housing is made from transparent material, which is often found on the outer surface of an aircraft.


What is the difference between sheathed and non-sheathed cable?

Cable sheath current is a current induced in the sheath by radio, magnetic or other interference, or a fault condition. The cable sheath should be grounded at one end so that this current flows to ground safely.


Why you are using capacitive hat in short antennas?

Capacitive hats are used to alter the distribution of the current on a short antenna so that the antenna current is not concentrated near the ground. A whip or short antenna can be modeled as a series of LC circuits in which the capacitance per unit length is highest near the base and the inductance per unit length is highest near the top. A capacitive hat simply adds capacitance to the antenna. It basically makes the antenna seem longer, but maximum current is still at the base.The reason why you'd want to make your short antenna longer, is to obtain the antenna's resonance frequency. The length required to do this is a quarter or a half of the wavelength of the radio wave that it's receiving. At resonance, the electrical resistance of the antenna drastically drops, which effectively increases the Q factor, or quality factor, of the resultant output signal. The term Q factor is simply a measurement of how good the clarity and stability of the output signal is, the higher the better when dealing with radios and televisions.Of course, instead of using a capacitive hat on your antenna, you could always physically lengthen the antenna itself. However, considering that commonly-used radio waves can be up to 10 m (33 ft) long, your antenna would have to be about 8 feet long, which would make using your radio a bit awkward.

What is communication system of the aircraft?

Generally speaking, VHF or UHF radio. VHF is also used to communicate with ground personnel (heli logging, SAR, firefighting, etc). The 'system' consists of a radio, antenna cable, and external antenna. an intermediate antenna switch can be used to allow multiple radios of the same band to use the same external antenna.


What did Andrew alford invent?

Andrew Alford is known for his work in developing the Alford loop antenna, a type of radio antenna. It is commonly used in shortwave radio receivers for its compact and efficient design.


Can a xm satellite radio antenna be used for a cell phone antenna?

An XM satellite radio antenna cannot be used as a cell phone antenna as they use a different type of connection. Satellite signals operate on a different frequency from cell phones and use different technologies in their antennas as well.


What is a car antenna booster used for?

A car antenna booster is used to 'boost' the radio waves of the car's antenna. This is usually used to improve radio quality and reduce static that might be heard.


What can one do with a DTV antenna?

A DTV antenna is used to capture digital television signals. By law, all television signals in the United States must be digital, and this type of antenna is used by customers who do not subscribe to satellite or cable services.


What type of cable is used for satellite connections?

What is a hertz antenna?

A Hertz antenna refers to a type of dipole antenna that was invented by the German physicist Heinrich Hertz. It is a simple antenna design with two conductive elements used for transmitting or receiving electromagnetic waves at radio frequencies.


What is the cable used for linking the satellite cable antenna to the receiver?

We use a RG6 coax cable from the dish to the receiver. The cable used between the receiver to the TV varies.

Technical term for the kind of cable that carries a tv signal?

There are two types of cable used for television radio frequency signals: 300 ohm twin lead flat cable and 75 ohm coaxial cable. The twin lead is typically used with a rabbit ears antenna and coaxial is typically used with roof top antenna or cable TV setups.For television baseband video signals coaxial cables are usually used.However for digital television baseband video signals these are not adequate and special cables (e.g. HDMI, DVI, DisplayPort) are used. These cables are typically many twisted pairs in a common shield.answer is Coaxial cable


What is the function of RG6 cable?

RG6 cable is a coaxial type commonly used for domestic video systems. It is most often used as a feed from an antenna or from a satellite dish to receivers. As well as RF signals, the cable can also be used to carry base band video signals although this is not a common application for this type of cable. There are a number of connectors used with it including F conectors, BNC, RF and UHF types.
