Antenna can not be removed only in one axis by 90 ° tilt. For transportation you should remove the WLAN stick.
RX / TX is through the large antenna expected to be good. How good it is, I will not say anything. I have about 20 colleagues who fight for the favor of the bandwidth in the 2.4 GHz. On top of the low performance of Banana Pi, so I could not tell where the bottleneck is.
a star I would give for the somewhat inflexible antenna, but since this does not bother on a PC, for example, and it would distort the review, I still give. 5
In short, I would buy it again.
