I would love to be able to change out my old Teltonika RUT that is installed in a QuWireless Antenna mount fitted at the top of my mast with a more modern Mikrotik one.
You guys need to look at a weatherproof 4/5G router, with at least two micro-sim cards (or an e-sim) suitable for mounting at the top of a mast (so not too heavy or large) that can use PoE. Personally I would not use any WiFi (or use it to connect to the marina's wifi) routing traffic to my Mikrotik router down in the saloon, which has the dual band WiFi on it.

Agree there should be some better, outdoor/marine 5G options...

Now the LtAPmini could work. You need to get some SMA pigtails and wire them up to the antennas, but's otherwise fit the bill. Other than the modem is old, but can be upgrade since it's miniPCIe slot inside.

The wAPac is more powerful (and ARM-based) but only single SIM without any e-SIM support.

I agree as well :)
