How Do Cell Phone Signal Booster Antennas Work?

[@chrisa2351]

That was a very simple and easy way to understand how an antenna works. Thank you! I assume a cellphone booster just does the same thing. It receives with one antenna, amplifies it, then spits it back out another antenna? That way your cellphone "thinks" thinks its getting a stronger signal. Although that still clearly means that a cell phone booster is only as good as the signal it receives. But if you could get that cell phone booster's antenna (that's probably a bigger and better antenna) up a little higher, and outside your own house, it could make a big difference if the boosters transmit antenna is back in the house.

your info helped out alot thanks man my phone was always roaming now i have 3 bars or more cause of what you showed me in this video.... i place those wires in back of my phone right underneath the antenna of my phone and wow 4g with 3 bars.... i give your 5 stars out of 5 thanks buddt

[@humeyra127]

Hello can you explain how did you do that? I need this kinda device right now.

[@kreynolds1123]

Decent video on a few antenna bacis, but nothing on how cellphone booster works

[@THOMASTHESAILOR]

Nice explanation, Maybe you should have touched on wavelength.. The length of the wires can catch a specific radio frequency more efficiently, if it's the right length.. 2.4 ghz Wifi should be about 4.9 inches long..

[@knowledgepower3693]

how do you use that in regards to cell phones

[@teoval1827]

At 3:14 , it is implied that the current is maximum at the sides of the antenna and minimum at the center, but it actually is the opposite , the maxiumum current fluctuation is at the center of the dipole and the maximum voltage fluctuation is at the sides of the dipole. en.wikipedia.org/wiki/Dipole_antenna

Love to see you again

[@paradoxlab2023]

Very nice video. Subscribed

[@historyexplorer]

So if i understand correctly, a satelite radio antenna could work as a cel phone booster if there is a receiver?

[@neweraccount5615]

Ok I have an old tv antenna on the house. Huge aluminum and not used for anything so I’m trying to figure out how to use that to get a stronger cell signal.. Other than that antenna what would I need? Old router? Repeater? Amplifier?

[@Y_creatorr]

Thanks you man good luck

[@Ajazahm]

how we can plug antena to phone wthout external antena jack sir? plz

[@1724nine]

Tommy lee jones is that you?😂

[@anthonysanchez-ex2kl]

i have a crazy idea... what type wire and antenna can I raise up a decent distance, with a weather balloon to get cell service in the woods... and how do I connect to my cell phone?

[@IqbalMahmudweb]

Very good

[@MrOldhoot]

I bought a phone repeater with an external aerial. When I put an ohm resistance meter across the external antenna pins I am getting a 100% short circuit which is somewhat puzzling as the internal antenna and other similar aerials I have tried do not show a short. Having taken the cover off, it seems it is designed this way. The repeater doesn't work with it connected either, the LCD signal displays just flash but that could be lack of signal problems. How is this supposed to work shorted directly back to the earth side of the coax cable?

[@tajsourav9583]

Could you show please, how to easily make a signal booster any things, such as any circuit. Thanksgiving.

[@arthurbright1625]

Thank u

[@qazimtahir]

Good presentation sir. I want to make a HIGH gain antenna myself for 4g internet. Can you please give me any good idea?

[@ershekharsolanki]

Nice video

[@michaelmcghie]

Thanks very helpful. Will any antenna amplifier work on any device

[@masadzulfqar7696]

Yes one device is available in market which work as a amplifier gsm repeater

[@muhammedayyubsm3647]

So can we use a dipole antenna as a cellular repeater?

[@off-gridhillbillystyle3735]

I want to make a cell phone booster. How would one magiver one ?

[@TechnicalGuru__15]

Not a insulator that co-axial cable that is TEFLON 50 ohm resistance

[@off-gridhillbillystyle3735]

Hey done you still with us?? I want to build some.sort of DIY receiver thing. Got any tips?

[@user-rm5oj4ew9q]

So I picked up 2 dipole antennas that are capable of 700 megahertz to 2100 megahertz send and receive I'm going to connect the two with 50 ohm coaxial cable one will be on the roof one is going to be in my home I understand that they'll induce signal with the dipole antenna. But what type of current do I need to put on there to have the signal jump out or will it do it by itself? and what type of current are we talkin? like can I put a coax DC converter in line? Would like a 12-volt current on there be enough?

[@kennykrichburg6691]

I like this

[@elhamsultani1289]

Hi I have problem with 4g signal out my home I get very good signal but inside the home it's like 120dbm can u help out to have a simple booster

[@ravanabrahmarakshas4263]

thanks. great.

[@uniquesensitivesnowflake7366]

Whats the purpose of mhz, cause booster described as they have 900mhz. I dont know what its purpose

[@suhtangwong]

The more there are, the faster your speed will be!

[@valveman12]

Could you please explain how you can have current flow with an open circuit?

[@johndoe-es7zh]

Is the energy flowing? Or is it just moving. What if you have a a cylindrical object and you put beads or marbles inside the cylinder. Well when you tilt the cylinder vertically up and down so that gravity flows the marbles in one direction towards gravity. Now rotate the cylinder 180 degrees and the beads will flow to the other end of the cylinder. If the reason a conductor allows electricity to flow along it is because it has 'loose' electrons if we change the balance of energy along the wire at one end with a relative positive at one end and a relative negative at another it will act as our shift in pull on the electrons generating a tendency for the electrons to cling to one side or another. Capacitors and inductors don't complete a circuit in a physical sense either but we use them to transfer electromagnetic energy regardless in a complete circuit. I'm not saying this is how this process works but just what I've been learning and gathering over time. Electricity is a lot less like water mechanically but a lot like it in how it transfers it's energy. Because how things transfer energy just seem to work in similar ways in certain frames of reference.

[@valveman12]

@@johndoe-es7zh *Capacitors and inductors don't complete a circuit in a physical sense* This comment is entirely incorrect! Capacitors do have current flowing until the plates are charged and then the current stops. What is left is a static charge of the plates. Inductors have current flowing through them and create an electromagnetic field. When the current is removed, the field collapses creating a reverse current flow until the fields are depleted or the inductor is reconnected...

[@johndoe-es7zh]

@@valveman12 you're being a bit obtuse if you think that's what I'm saying. Electrons do not hop between one plate of a capacitor to another they actually rely on this fact. So what I was trying to point out to you is that maybe that isn't something that's required. And the balances and movement of charges is what is the primary motive force in electrical phenomena and the radio connected to the antenna creates the driving charge that produces the frequency.

[@valveman12]

@@johndoe-es7zh *_If being obtuse means correct an error, then I'm obtuse I guess._* *_Your Comment_* "Capacitors and inductors don't complete a circuit in a physical sense either but we use them to transfer electromagnetic energy regardless in a complete circuit. " Current does flow when a capacitor is charging. Not across the plates, but the electrons accumulate due to the attraction to the positive plate. Inductor, the current flows through it generating a magnetic field. Stop the current and the magnetic field collapses and the polarity of the coil changes. As for antennas, the high-frequency signal that is sent to the antenna is converted into Electromagnetic Waves. Efficiency is a function of impedance matching to obtain the best coupling for maximum output. Perhaps you know this already so I don't want to assume.

[@glendelossantos7699]

sir would you explain to me ,why is it my cellphone still won't receive signal from my antenna.I make an antenna that the same frequency to my cellphone 1500-1800 MHZ. 4G..Sir what is the length of the dipole of the antenna and the director..please help me please sir..

[@muhammadsufyan7051]

Sir i want to build an antenna at my home i have no signal so that i may signal in my home.

[@ademmohammed3939]

can you help me modify ra-wn712 v1.1 mini adapter to connect an external antenna to it?

[@BigBoy-sf4nx]

hello is there a way to make a cell phone antenna that doesn't need to be plugged into the phone device? can I just hold the antenna and have it work that way or no? thank you for the time.

[@kevinrich9471]

@ Big Boy: research passive antennas. 😀

[@lolilelalw6849]

Yana Yana K you just plug in to your ass

[@riiishb1005]

Yana Yana K bro you have gust plug the white and green wire in an antina or you're own TV dish of the data cable and then connect to your phone ....

[@robtt1313]

Yana K can you use a wow the Shelf router antenna hook it up to your cell phone

[@Lilmiket1000]

apparently it seems to me that you don't plug them into your phone. one antenna goes outside your building or in an area with a good signal. and it recieves the signal from outside and broadcast it inside without any need for a physical connection to your phone or power.

[@krunalmaheshwari]

How can i distort mobile signal..thereby stopping user to talk on call..but to recieve call

[@krunalmaheshwari]

@Theholocaust Isalie dear sir Mobile jammer completely blocks the signal. If you can provide me your email. We can have further communication.

If that's all it is then why does it cost 100s of dollars

[@dhesatya]

just the theory

[@vlad3k]

Using here and there so much i cant believe this guy made the most boring version of this topic.....

[@sc8366]

Mans Shirt is way to large for him. It's as if the Company just threw him a Company shirt real fast for this Video. Not good!

[@ramjet4025]

OMG, A spam video. Confusing false information about Coax. His Antenna theory explanation shows a lack of knowledge, and then, he spews out confusing information that does not give a watcher the basic information required. This is about the poorest explanation of how an antenna works that I've ever seen. Antenna radiation is as easy as well, watering the horse, stand close and your aim will help, radiation can be like a sprinkler, a spray , a mist or anything in between.
