I didn't know they did an outdoor hub. I've been using a Three 5G broadband hub for a few years. I bought my own Pointing external antenna and connected it to the hub. It works well. The antenna boosts the signal significantly (I forget how much exactly).

The issue I have isn't the hub or antenna, it's Three themselves. Quite often the 5G gets slow, as in unusably slow. The signal is strong so I assume it's an issue with their masta or over subscribed. It doesn't happen as much these days though.

Because I was unsure when I first wanted one I opted for a monthly contract and not a year. It allowed me to test how well it works before cancelling my existing broadband.
