There are two antennas cables doing same function at iPhone 7 plus?

Please, see this picture to understand what I mean.

And it explains better the situation:

I think I have damaged one of these two antennas plug, because it is been very difficult to connect.

Even with just one of these two cables connected, I have done all tests and seems all functions are working.

I have looked their funcions in some forums, youtube etc, but it seems these cables does the same function. So I am thinking that one is a primary antenna cable and the other is secundary, maybe acting as a substitute if the first one does not works. But I am not sure yet.

And my apologies, I do not speak english very well and maybe my explanation is confused.

The two coax connections are for different antennas Cellular and WiFi. What I think is confusing you is the fact there are two other antennas at the top of the iPhone which also have the same function. Apple did this to improve signal coverage in case your hand gets in the way blocking it

Sorry, but I did not understant the functions yet. Even one disconnected cable as you can see on updated pictures, 4G signal is working, WI-FI is working. I also have tested calling for a number and it is working.

Sure that makes sense! As you have two of each antenna's one on the top and one at the bottom.

Think of it this way you have two water taps and two hoses that connect to one hose (Y connector) You are watering your plants as you turned on both taps the water is coming out both. But, now if you shut one of the taps is the water still coming out? Yes! As the second tap is sending the water instead of both.

This is the same design used here one on the top and one at the bottom so if you block one antenna the other will still be available.

So this parts exist for improve signal or do you think it acts just as a secondary function, working if the first one does not works?

I think you need a way to visualize whats happing here. Lets imagine you're in a room with a stereo system with two speakers. Sitting down in the middle of the room you can hear the music from both speakers if you moved just in front of the left speaker all you really hear is from that speaker, if you move to the right speaker you just hear the right speaker. So in this simple example you get part of the of music when you bias your self in front of each of the speakers or if you are just in the middle you get both speakers in full stereo.

Your antenna's work in the same fashion!

Now lets push this a bit further. This time someone disconnected the left speaker so you only get the right speakers music. Unless you knew the music was in full stereo you wouldn't know.

So if one of the antenna's was not connected or blocked you wouldn't know!

Ok. Thank you!

Hello. What if there is no celluar activity? It keeps saying "searching..." but there is no celluar network. So does that mean both celluar antenna sticked to the lightning socket and the top antenna are broken or there is a significant damage on the logic board?

I recently changed the lightning socket and this problem came up.

There are quite a few reasons for the 'searching...' condition!

The phone does not offer the correct cellular modem for your county or for the carrier based on the SIM you are using. Review the iphone's specs and your carriers bands. You may need a new SIM.

Within the phone:

● The modem chip is damaged

● The phone is liquid damaged

● The antennas are not connected or the frame (antennas) is damaged so there is a short across the base and antenna segments

I'm sure I've missed a few other possibilities!

How about creating your own question with all of the gory details on what happened.

One is long range one is short range.

Not really,

Unless you're equating it as Cellular is long range and WiFi is short range.

The two cellular antenna's are the same in physical size and support the same bands, likewise for the WiFi antenna's.
