There are four what look to be some kind of ports labeled R2-G W1 W2 R1 under the battery cover.
What are those?
I believe those are connections to use an external antenna

Does anyone know the antenna connector configuration for the XDA?
I have some ideas of connecting an external antenna but I don't want to
drill holes into the case if I can get away from it.
OR
A PCB layout of the internal antenna?
I also have a wrecked XDA (had a close encounter with the sea) and maybe it's 2 1/2 mm socket strategically mounted somewhere with some miniture RF coax to a suitable place might work.
I would appreciate your help.

Hiya guys, I've always wanted to know, and im sure there is one person on here that know this, what the round port is on the back of the XDA2 to the right of the camera?
Also, that same person will probably know what that other port does on the inside right below the battery?
Just wondering. I though the port on the back was a signal booster or something? But hay! It could be anything!

external gsm antenna connector
The port below the battery is where the backpack connects (contains battery and compact flash port plus monitor connector)
Hi all, I have a galaxy s4 i9505 and was wondering if anyone knows of an external antenna that will plug into the antenna port but instead of being attached to external antenna (such as a whip antenna etc), is attached to a flat small square or rectangular antenna that will fit behind the case (between the battery and case)? so I don't have to carry around an antenna in my pocket and can leave the antenna connected all the time.
thanks
Brett.

Hi
I accidentally broke the antenna port on the charging board even lifting some of the traces from the board itself. However I have since then not noticed any problem with the reception at all. Does anyone know what the antenna connected by the internal antenna cable is used for? Is is a specific band or is it a MIMO think or something like that?

I'm not the first to post about this but I figured I would post to share my experiences. I have two head unit, a PX4 and PX5 both with major WI-FI performance issues. I would get .5Mbs download speed, yes that less then 1Mbs. There are several post about this issue, some suggested adding second antenna. I can happily report, that after installing two matched antenna's the WI-FI speed has significantly improved. I am now getting download speeds of around 30Mbs.
Some Notes:
* Both units already had solder points for a second antenna.
* Best WI-FI performance if the antennas are matched, so make sure the antenna you purchase fit the existing SMA connector on the back. If you have only a wire sticking out the back, then you'll need to desolder it and add two antenna SMA connectors.
* I used a multimeter to find the ground from the antenna pad. The ground pads where connected together electrically, so set the multimeter to test for "continuity". Both head unit had the pads opposite, so using the existing as a guide, solder the new antenna in the opposite direction.
* The soldering isn't to difficult but previous experience is required. This should not be performed if you have very limited soldering experience.
* To strip the antenna for soldering, strip the outer insulation off. Then pull the outer ground shield back and twist it so it bunches up where the outer insulation was stripped off. The strip the inner insulation off. The gap between the ground and exposed antenna wire should be about 2mm.
Because of the limited space I used very short antennas, search Amazon for "bestseller2016 2pcs 2400Mhz 2.4GHz 3dBi RP-SMA Male WiFi Omni Antenna for Linksys Booster" to see the antenna I used.
I purchased the SMA connector off ebay for few dollars.
Sorry, I have pictures but am unable to post since I don't have enough posts.
