What is passive antenna?
A passive antenna is an antenna that is not powered by an amplifier.
Is antenna passive or active component?
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.
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 .

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 satellite radio antenna active or passive?
A satellite radio antenna is typically considered a passive device. It receives signals transmitted from satellites but does not amplify or generate its own signals. The antenna captures the radio waves and sends them to a receiver, which processes the signals for audio output.
If antenna is passive than how can it add gain?
Antennas provide so called passive gain, which means it comes from particular shape of the antennaThe gain of an antenna is a passive phenomenon - power is not added by the antenna, but simply redistributed to provide more radiated power in a certain direction than would be transmitted by an isotropic antenna. If an antenna has a gain greater than one in some directions, it must have a gain less than one in other directions, since energy is conserved by the antenna.SOURCE: wikipedia.com
Is an antenna active device?
In electronics any device that just pass along a signal by its characteristics is defined as passive.
How do you make a scanner antenna?
You don't.
If your power antenna on a '91 lesabre jams up but the motor keeps trying to make it go down how can you stop the motor and fix the antenna?
unplug the electrical from the antenna. replace antenna.
Is what do you prefer to be called by active or passive voice?
