An active antenna is an antenna which has an amplifier attached very closely to it. The antenna/amplifier system is called an active antenna. It is used for receiving signals only. The idea is to set the signal-to-noise ratio (SNR) before the signal travels along a transmission line where it is susceptible to interference and loss.

∙ 12y agoGSM antenna is a "PASSIVE DEVICE".
Because Passive device don't have its own internal energy to operate they require external energy source ( example of active device is battery).

What is the difference between active and passive component?
Active means devices that perform functions in a non linear fashion [amplifiers] passive are components that perform according to a set of linear rules
What is the Difference between active filters and passive filters?
Active transducers are those which require electric current (a source of energy) for working, while passive transducers are those which does not need an external source. Passive transducers directly produce electric signals without an external energy source.
Active component in resistors and capacitors?
Resistors, capacitors, inductors, diodes are all passive components.
Rectifier a passive component?
yes, it is a passive component.
What is the meaning of electrical components?
Electronic component are those component which are used to make the electronic circuit it may be active or passive . some active components are - Diode ,FET,BJT,MOSFET, and HEMT etc. while passive component are those device which can not process/amplify signal like- resistor capacitor inductor etc.
Is the inductor a passive component or active component?
passive
Antenna is a Active or passive devices?
it depends on existing amplifier or not , if after antenna there's an amplifier it called active else it called passive which less sensitive that active .
What are Passive components and its characteristics?
A passive component does not interact as an active component like an amplifier
Is transistor active or passive element?
it is a active component.
Is an Aeriel on the roof a standard or an active antenna?
An active antenna is powered antenna, this includes a RF amplifier and a power supply so it must be "plugged in" somewhere. A standard "passive" antenna has no amplifier.
Is a tap on a pole passive or active?
"a tap on a pole" is not a complete sentence. It does not contain a verb (a key component in active and passive voice), so it is neither active nor passive.
What is the difference between active and passive component?
Active means devices that perform functions in a non linear fashion [amplifiers] passive are components that perform according to a set of linear rules
What is passive antenna?
A passive antenna is an antenna that is not powered by an amplifier.
What is the Difference between active filters and passive filters?
Active transducers are those which require electric current (a source of energy) for working, while passive transducers are those which does not need an external source. Passive transducers directly produce electric signals without an external energy source.
What are the component of oscillator?
It can contain active and passive components with a positive feedback loop.
Why capacitor is an active component?
A: If you are reading this out of a book that book is wrong resistors capacitors coils are passive components NOT active
Is an antenna active device?
In electronics any device that just pass along a signal by its characteristics is defined as passive.
