Spitz questions

I’m using a Slate with a e3372 modem and getting disappointing 4g performance, about 10 mb/s,

Thinking about buying a Spitz, would it be reasonable to assume I can get better speed with the cat 6 modem and larger antennas?

Can I use external antennas on Spitz? what connector?
Thinking of buying this:

I would prefer to buy from Amazon in europe to avoid import taxes but I cannot find it there yet despite other GL routers are available.
Will it be available from Amazon?


Not yet in Amazon.

It use SMA connector, which is common for 4G LTE.

Its EP06 module performs good in the EU. We got feedback that it can reach 60Mbps. But it really depends on the location, band and carriers.
