Thanks for letting us know and doing the leg work once more! Just a note, it prob would be a waste of time 3xCA as port is just rated 10/100 on LHG4 and LHG6?

Is the upload not band related? eg. availability? Or is it the modem/hardware used that will dictate? Eg. if i had 7mbps on b1 on LHG would i not get 7mbps in the same situation on b1 on another modem?
For example, in this situation, the speed here is circa 80mbps, in north cork! This is a LHG LHG4, and only has a 10/100 port, upgrading the modem wouldn't benefit this situation only another 20mbps throughput is available on the port! I have been microsoldering for years, but I'm not sure a direct swap of the jack would help matters, im sure there's more to it.

The upload speed depends a lot more on the antenna gain and VSWR than the download speed, i.e. how well and efficiently it focuses the signal transmission towards the mast. The dish is unable to focus the low frequencies on the low bands, so with band 20 the LHG performs no better than an omni-directional antenna, whereas the Iskra and other LPDA antennas offer better gain. If the mast was closer where I could use band 1 or 3 as the primary band, the LHG would make a dramatic improvement on the upload speed also.
Based on the above reading, it's probably not worth upgrading unless really need the additional 20Mbps. With such as a strong RSRP, the upload speed is likely as good as you'll get as the upload speed usually does not improve much further once the RSRP reaches around -85dBm to -90dBm from my experience.

The only reason I have upgraded the modem in my LHG is for upload Carrier aggregation which hits 45 up on a good day and 30 on a bad day.

I did some further testing with a borrowed GoMo SIM (Eir network) which has band 28 coverage on the same >50km distant mast I pick up Three from. Unlike Three, Eir has recently become a right pain for trying to use cell locking to a band 20 or 28 cell when a band 1 or 3 cell is present. It kept trying to transfer my modem to band 1 or 3 as the primary band causing the connection to cycle up/down in a loop due to the distance. This showed up in the log as repeat "NW Detach" events:
The only way I managed to eventually get it to settle was to turn the dish antenna away such that bands 1 and 3 became very weak (around -120dBm). After a minute the connection finally settled on band 28 and was able to turn the antenna back towards the mast, where it then aggregated band 1 or 3 instead of trying to switch to it as the primary band. Disconnecting (e.g. reboot) would cause the issue to return until I turned the dish temporarily away again, so this rules out ever using that mast for Eir here.
This modem uses the same cell lock AT command as the EG12 and RG502 modems:
The upload speed is roughly the same as what I get on band 20 with Three from that distant mast with this setup. It was also interesting to see what download speed I could get with band 1 from Eir here as Eir requires an RSRP of -103dB or better on band 1 to aggregate it. The Iskra antennas with past testing could only achieve an RSRP of around -107dBm on band 1 with Eir, resulting in the network not aggregating band 1.
Band 3 performs better on Eir, again requiring turning the antenna away until the cell stopped trying to hand over to band 3 as the primary band.

Is it possible to update the firmware of the EM12-G while it is in the LHGG LTE6?
I am currently on EM12GPAR01A21M4G (Not sure what revision) and everything is working fine.
I wonder is it worth updating?

@waveguide, if you download any of the firmwares you can read the change log and see if anything benefits you.
To upgrade in situ, you would require a DFOTA update file and I've not found one yet.

Which LHG did you put it in? as the RJ45 jack on most LHG are only 10/100 rated.. Also, the LHGG lte cat18 can be got for now 206 on getic which has a gigabit port.

I installed it into an LHGG-LTE6 which has the gigabit port. It has been working well since. I was looking at the Cat 18 LHGG, but I think I will wait until there is a 5G model available. (Whenever that is)

That makes sense now! outdoor 5G stuff is going to be expensive for a long time. Im using ZTE FWA and Huawei WIN outdoor systems for 5G, but have zero control over the cell's and its always dropping signal. Only idea setup is the Huawei WIN in high capacity 5G on n78. I find the cat18 on 3 CA outperforms any ZTE FWA on service even with the best of signal quality.

The LHGG-LTE18 has an m.2 slot and a R11mL-EG18-EA, this could be replaced with the R11mL-RG502Q-EA or similar
RM500U-CN looks tempting:

have had a great experience with 3x CA on the R11mL-EG18-EA....what improvement will R11mL-RG502Q-EA offer? Other than the 5G offering.... Also, i see it doesn't support the high capacity 5G n78 band, only the -CN version does. have you had any experience with it? Trying to get the optimal setup for the best value without unnecessary cost...
Purchased the LHGG LTE18 for 206 euros and trying to justify paying any more to see what benefit it would bring if much/any. CAx3 band 28, band 3 and band 1 and working well.
There aren't much modems out there greater than cat6 that are mini PCIe all seem to now be m.2

RG502Q supports N78, it's the default modem in the Chateau 5G and 5G ax

Sorry my mistake, on checking the data sheet again it does show n78. not sure why i missed it the first time its the same sheet im looking at the first time... maybe need more sleep!
The datasheet found here:
https://www.quectel.com/wp-content/uploa...n_V1.2.pdf
has anyone seen MikroTik RBLHGGR (LHGG R) without a modem to save on having to buy one with a modem and then swap it?

Yeah, that would be a nice replacement in an LHGG. Are you going to buy one and test it out for us?  The EM12-G I have installed is doing quite well. I couldn't justify changing it for a while. I am not even sure my local mast has 5G enabled on it yet. I don't understand why Mikrotik haven't released an LHGG device with 5G yet?

Unfortunately that board will not work in an LHG' at least not as a direct swap. The ports don't align up and the antenna elements are physically attached to the back of the LHG PCB, which run to antenna connectors near the PCIe slot.
That routerboard however would work nicely inside the Poynting EPNT-2, such as for those that need high gain on the lower 700/800/900MHz bands.

I've got a LHGG and want to order an RM502Q for 229usd or the RM520N for 205usd. would have it in a few weeks and will post my results. can't decide which modem to buy, anyone got a preference?
