Both the antenna 5 dbi that 10 dbi antenna are good (she even antenna and connector) but I have seen no improvement in signal strength reception. Instead there is a slight deterioration compared to the original antenna (2 dBi). Degradation is slightly higher paradoxically with 10 dbi with the 5 dBi. So I returned the original antenna. Antennas tested on a relay station for Livebox Hercules.
