Mifi routers with an external aerial socket

Linton

My Huawei E5577C mobile router's battery is dying and it seems difficult to get a replacement other than from 3rd party suppliers with poor reviews (both the suppliers and their batteries).  So I am looking for a modern replacement router.  The router needs an external aerial on a long lead since it is being operated from inside a metal tube (a narrowboat).  I already own one  that worked well with the E5577C.

The problem I have is that the adverts and data sheets dont state whether specific mifi routers have an external aerial socket or not.  Can anyone recommend a mid-range mifi router that definitely has an external aerial socket?

Thanks for any info.

do you really need a mifi router with a battery, wont it run without one. You could run it from the boat supply using a 12v to USB adapter if you aren't connected to the mains supply.

Alternatively a standard 4G/5G router will work quite happily from the 12v boat supply or you could get a converter if yours is 24v.

We use a Huawei when we are away in our caravan and run it from the 12v supply - this one https://www.amazon.co.uk/Unlocked-B535-232-External-Antennas-Worldwide/dp/B07ZFSX8LB but others are available

ebay sell battery at £9

It looks like Huawei E5573 share same battery with E5577C. There are people selling sealed O2 locked E5573 for £17 if you do not trust third party battery.
(Swap the battery, sell the O2 mifi to CEX for £8)

CAT 7 Three network unlocked Huawei E5783 (open-never used) £30

CEX sell 5G ZTE MU5001 (vodafone) for £115. I have one from vodafone, it is unlocked
