[X Style (Pure) Q&A, Help & Troubleshooting] NixonP:
Skip to *** to bypass forward/story. I tend to write stories Also pics of in question mb and circled sma's (the whole point of this) included. Look at last pic.

Here is the deal to cut off any and all why questions. I have a Deeper Bluetooth fishfinder which is not modifiable, but it is awesome, and I have a big fishing trip to Canada in one month.

I've used it a bit, but my range, while different depending on the device I use of course, is always in the 30-50 foot range max. People have modified their bluetooth antennas for a while to greatly increase the range which is a good thing for a cast out fishfinder, I want 100 feet of range sitting in a boat in slightly choppy water, it is doable with an antenna hack, especially a directional one that I will use for this.

I have replaced many screens and digitizers on androids, including my x style xt1575 just last week, besides that glued on back it was super easy, even figuring out how to save my colored speaker bezels was easy ( a small sharp screwdriver underneath the center of them pops them out then just pop them into the new phone once all back together, and all the stuff behind those custom speaker covers can transfer to the new screen/frame folks, its easy you just lightly pull n the stuff on the back of the frame you are tossing anyway.

So I've used rp-sma adapters to add external antennas to routers before. Made a giant difference. I'm sure an external bluetooth would be the same, but I noticed something. All the sma plugs on the xt MB look like they already have a plug on them which goes a couple millimeters then looks like the wire goes through to the back of the motherboard, where I see from the i FIxit video they only are using coper layerings on the back of the motherboard as imprinted antennas, but I forgot to look closely when I had it apart last and I did a very good job of gluing. I don't want to break out the heat gun again until I'm sure which sma or coper secion it is, I could use either place but I'd rather use the sma though I may be able to fold up a wire antenna behind the motherboard soldered to the copper crap antenna... don't know if there is room POINT: I've been building computers for 20 years and know what I'm doing, but I dont know which sma is correct considering how many antennas these things have now for every service in the US, (anyone have a link to the motherboard layout diagram that would be the ultimate answer)

*** So with all that forward, does anyone know exactly which rp-sma (standard internal antenna connection on everything these days) on the MB of the xt 1575/1572 is for the bluetooth antenna? From the iFixit videos I have a guess it is the one near and partially under the top speaker, and I know I'm going to be stuck with dongle hanging out of my phone when I'm done but I don't care. On the back of the motherboard there appear to only be copper sections acting as antennas opposite all the rp-sma connections on the front (watch full ifixit teardown and you can see there are no antennas on the xt1572/1575 besides copper squares painted on back of MB. I imagine that each close grouping o three is 2 5ghz and 1 2.4ghz wifi antennas (so it can do 300mbN and Mimo 2x2 AC. The two at the bottom near the power jack I'm not sure one of the cellular I imagine and the two right next to each other near the center a different band of cellular I imagine, 11 antenna connections total on this MB each with a connector already on it but going to a crap antenna on the back, but that one slightly underneath the rear camera by itself looks like it could be the winner. Pointed out in 3rd Picture.

This fishing trip to Plaisteds Camp in Saskatchewan cost 6k. (watch the Will Farrel movie coming out soon about this guy, Ralph Plaisted was the first man to reach the north pole -proven fact verified by US military at the time, previous explorers were hundreds of miles off)

Last time I went I didn't have the deeper just a bunch of androids mapping the surface and taking fishing and bear videos (plus a new feature of the deeper is it will make a full map of an entire lake bottom so I can identify rock formations and, **** is amazing) This is one of the best Pike spots in Canada, I averaged about 30 30+ to my max of 42 inch pike a day, and all the walley I could eat. IMPORTANT lol.

Any knowledge on the right SMA or a diagram of the MB or any other proof of the right antenna to jack off of will be much appreciated.

PS anyone know how to make a cheap ass gieger counter? Fishing camp happens to be only a few 5-10 miles from the gigantic uranium mines in northern Canada. Like the Core samples are laying all over the area lol and I've been curious how radioactive those discarded old samples are.
