In electronics any device that just pass along a signal by its characteristics is defined as passive.
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.
An active antenna has a amplifier built in, a standard antenna does not. AKA powered antenna.
An antenna is analog it is not classified as being a digital device.
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.
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 .
To replace a ferrite antenna with a whip antenna, first, disconnect the ferrite antenna from the device, ensuring the power is off to avoid damage. Then, connect the whip antenna to the same point where the ferrite antenna was attached, ensuring proper orientation and secure connections. Finally, test the device to ensure that the new whip antenna is functioning correctly and providing the desired signal reception. Adjust the positioning of the whip antenna as necessary for optimal performance.
An antenna functions to receive electromagnetic signals from a transmitter and convert them into electrical signals for a device to process. It also transmits electrical signals from a device into electromagnetic signals to be sent to a receiver.
An antenna is an electric device that involves two way communication. It converts electricity into radio waves and vice versa.

A GPS device needs an antenna to receive signals from satellites orbiting the Earth. The antenna picks up signals transmitted by these satellites to determine the device's location on the Earth's surface.
No. Not even close. Tesla coil is a high powered device with causes electricity to arc through air. very dangerous. Antenna coil is an old school device used to manipulate reception.
