I've copied in the thread where another forum user experienced the same thing using CA with the LHG, which made my mind up not to purchase. Personally I'd stick with band 3 with that LHG. looks like good speeds. HNY

Thanks, ill have a look through that one

Unfortunately Emilia had no luck with the latency spikes on her LHG LTE6 dish with band 3+20 CA. She even bought a second one thinking the first was faulty and raised a support request with MikroTik, but they were unable to resolve the issue. She went into detail about her issues in the following post:
https://confusedbird.com/thread-16-post-183.html#pid183

The problem with band 20 is that the 800MHz wavelength is too large for the dish to focus it, so acts more like an omni-directional antenna on that low band. It can focus the shorter 1800MHz wavelength, which explains why it's a lot more stable on band 3.

You can try enabling cell lock to the band 3 cell in case it's cycling back and forth between the band 3 and 20 cell as the primary cell. To do this, first check what cells are available by typing the following command in the terminal section:
/interface lte cell-monitor lte1

The band 3 cell with the least negative RSRQ is likely the one you're currently connected to. For example, if the earfcn is 1700 and the cell ID is 10, the following command locks the router to this as the primary cell:
/interface lte at-chat lte1 input="AT*Cell=2,3,,1700,10"
(Replace 1700 and 10 with the chosen earfcn and cell ID in your list)

To remove the cell lock, type:
/interface lte at-chat lte1 input="AT*Cell=0"

MikroTik has a Wiki that goes into more detail about the cell lock:

If the issue remains, I suggest disabling the cell lock and deselecting band 20 as Comnsman also suggests, then fine tune the alignment to see if you can get the SINR reading any higher on band 3. Try also selecting band 1 to see if the mast operates on the 2100MHz band, which could give 3+1 CA. ComReg has allowed the operators to temporarily reprovision 3G band 1 for 4G use until April, so if you're lucky, that mast may also provide 4G on 2100MHz (until April).

Hi Sean,

Thanks for the reply. Checked cell monitor and all i have from the mast is B3 and B20, I have B20 deselected due to the latency issues. Only shame is i hadn't found your forum before buying one. I will try fine tuning its position tomorrow to see can i improve the SINR.
