External Antennas (AP1300-LTE)

I am using a AP1300-LTE and it is working great, I would like to add an external antenna to it (the router is inside and I could externally mount an antenna). Does anyone use external antenna’s with any GL inet devices? Any recommendations? I have been thinking about a QuOmni one, they seem to get good reviews!
Thanks all!

If you want to change LTE antenna I think you can just try.

I’d like to know if there is any good external antenna as well.

I’ve read quite a lot, I am thinking this one is probably the best, any one got any comments?
