Cell Phone Yaggi
Mt neighbor down the street has a brand new in the box SDYLE (4g) antenna in a garage a sale. He bought it new but after opening the box had no idea how to hook it up to get a decent cell phone signal.
I've never come across oe of these and would consider it for use to boost my house signal enough to get reliable data connection (Samsung IIIS)
The best I could figure out was that you stick the thing as high as possible and then run the included cables to your N-router you typically use for internet.
Is this correct and then does the router broadcast a signal that the phone can pick up through its own data connection?
Of course I have no idea ofr the relative band widths of all these bits, but the antenna is supposeddto be good 700-2700.
I woud negotite a price to buy it if I thought it would help somehow on the data end (I can make phone calls OK now)

If your 4G signal strength in your area is already good then any attenuation by using a more sensitive aerial won't make much of a noticeable difference.
Think of it like this. In order for the 4G base station to be able to "hear" people near and afar it tells those up close to "talk softly" and those afar to "talk loudly" so that the "volume" of each talking person arrives at the same level at the base station's "ear". If your 4G base station can already "hear" you well enough and you decide to use a "megaphone" (high gain antenna) then the protocol will force you to lower your "voice" - which can then introduce a bad signal to noise ratio.

I'm not sure what the word "voice" means in this context. The voice part of my signal is fine, it's the data part of the phone that doesn't have enough signal to work inside the house.

"voice" in my example is analogous to the radio wave generated by your 4G device.
In terms of voice and data with 4G networks, all traffic is digitised and is therefore all data. voice data consumes considerably less bandwidth and can be serviced on at least one data stream, whereas internet data will often request to use as many data streams as are available in the bandwidth of the frequency that the mobile tower operates (new generation devices can use multiple towers at once - if the network supports it). That is to say, there are a fixed number of data streams available at each mobile phone tower and your internet device competes for these finite resources along with every other device that binds to that same mobile phone tower.
If there are other nearby mobile phone towers available in your geographic region then by adding an external antenna you may be lucky and have your internet device bind to those further away towers, but they could be just as busy or worse during the times you use the internet. It all gets grey from here, does your internet device and mobile network allow you to bind to multiple towers? Is the network connection policy set by your mobile network provider to bind only to the tower with the clearest signal unless congested? Try testing your internet device outside and if you get better reception then an external antenna may help.
I use a 4G usb modem for my internet connection and find the internet experience to be very variable, I even once ran the usb modem off a 3m long usb cable to position it for better reception. In the end most of the annoying problems I've had have been, as best as I can tell, caused by issues inside the operator's physical network rather than their radio network e.g like their internet gateway going AWOL or getting oversubscribed. The fact that every now and then I can get near full modem speed means that the signal strength is not the main issue so I've long since ditched the 3m cable.

does the router broadcast a signal that the phone can pick up through its own data connection?
The term wireless internet can mean two things in current usage. It's essential that the correct application is understood. One interpretation is that it uses one of the mobile phone bands and the nearest cells to operate to either a mobile phone or 3/4 enabled tablet or laptop for internet usage. I think this appears to be the intention for the antenna under offer and it is assumed that it will be feeding a device which can utilize the 3G or 4G signal to provide the signal for the internet connection.
The second interpretation is where people understand wifi (or a networked connection which includes internet access) from a router whose internet connection comes though copper or fibre to be "wireless internet'. Strictly speaking this is not wireless internet at all - but often people think it is.
I think more specific information needed about your present internet equipment and connection before a definitive answer can be given. At present, based on what I think I read, it isn't going to assist..
However, it's midnight here - I've just come home from a party and I'm tired. This might be more clear in the cold light of day.

I think now I understand what has been said above. It was my understanding that the wireless modem ("N") broadcasts to my phone using WiFi but when there is no incoming cable modem (I dont have an ISP) it is supposed to use the signal from the antenna with sufficent throughput to supply data to the phone (frequency, amplitude and bandwidth).
For this to work of course the antenna needs to be aligned with the incoming signal (trial and error
and the frequency needs to be recognized by the wifi router. I was under the impression that an "N" band router meets this need ?

To do what you want your router will need to have wireless broadband capability and you need to supply a SIM card. What make and model router is it?
I don't have the router available, it's in another city.
Meanwhile the neighbor who had the antenna in the tag sale decided to give it to me for free to fool with. Which I wil do when I get to the router.

Not knowing anything about your Samsung IIIS does it not have WiFi capability?

Meanwhile I had another "expert" (anybody smarter than me) look at the doodads in the shipping box and he says there is an important part missing. I shall go back to the original owner and ask him if he might still have something with a mini antenna and a powercord laying around a closet shelf.
