There were some problems with catching the wi-fi signal.
Poizuchat question ebee bought Tyco antenna for 200r.
Sold all the things (for vertical / horizontal polarization), but we were in the tablet only need one. True zapihnuv antenna inside still had to hold it 30cm cable (if desired / skill you can cut it).
The difference is obvious. On a personal note, that in fact the reception became noticeably better catches, where before there was no signal. I recommend to use.
