An aerial amplifier and an active aerial are not the same, though they are related. An aerial amplifier is a device that boosts the signal received by an antenna, while an active aerial is an antenna that has a built-in amplifier to enhance the signal. Essentially, an active aerial includes an amplifier, but not all aerial amplifiers are part of an active aerial.
What else can I help you with?
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 amplifier an active element?
A: Absolutely
If you have a sub woofer do you need an amplifier?
There are two types of subwoofers. 1. Active subwoofers 2. Passive subwoofers An active subwoofer will have a built-in amplifier. A passive subwoofer doesn't have a built-in amplifier which will require the use of an amplifier, the use of a power source.
Will an unpowered subwoofer work when plugged into an amplifier?
A passive sub-woofer does work when plugged in to an amplifier. In an active sub-woofer ("powered") the amplifier is built in.
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.
Radio on vauxhall frontera does not work connections are good but why does the aerial have an electrcal connection on it what is it for?
Many of the small "bee sting" aerials (about 30Cm long) have an Amplifier built into the base, and this amplifier needs power to work.
What is the difference between an active antenna and a standard antenna?
An active antenna has a amplifier built in, a standard antenna does not. AKA powered antenna.
Does each separate tv in a house need a separate aerial?
No, one antenna with a RF amplifier/splitter and a coax cable to each TV will do the job.
What are Passive components and its characteristics?
A passive component does not interact as an active component like an amplifier
Is an aerial root the same as a runner root?
no
Is it power amplifier and inverter both are same?
No
Can you connect a normal bass speaker to a system that has an active sub out put?
An output for an active sub-bass unit is a line level signal, typically around a volt or so. It won't drive a speaker directly so an active sub incorporates and amplifier to drive the loudspeaker. The way to use a passive bass speaker is to take the sub output into another amplifier and use one channel of the amplifier to drive the passive speaker. It's an easy solution if there happens to be a spare amplifier at hand. If it will involve the purchase of a new amplifier, it may prove more cost effective to buy an active sub-bass unit instead. However, passive bass drivers tend to be used in higher quality systems so it might offer a great quality sound with a good amplifier.
