I have a Huawei E5186 4G wireless router. It has two antenna inputs, and those have been occupied with the default two "rabbit ear" antennas. I have also tried this external antenna I ordered from Ebay, and it is way better than the default antennas from Huawei. The problem is, that the signal is way more intense outside the house, and the antenna is not designed to be outside (in summer it would be fine, but in winter when its -25C/-13F outside its ruined).
So then I ordered this cheap outdoor antenna, which hasn't yet arrived. But the thing is, it leaves the other antenna input in the Huawei unoccupied. What should I do with it? Plug one default Huawei antenna, plug single antenna from the other external, or buy another one and put two antennas outside? What do you suggest?
