I want to use this router on a ship, and are planning to try connect external antennas for having best signals in every directions. Anybody with an idea what connectors i should use ?
@bmork is the man for this I imagine.
The ones on the board?
If your asking what type the connectors are, see:

I was thining of witch of the connectors on the board to use for external antennas.
The ones with U.FL connectors. They're labled "ANTx". Hope this helps.
Yes, this is what i assumed. There are 6 antenna cables, but i do not know witch is for lower/higher frequency.
I found this antenna i was planning to test , do you think i need 3 of this for best signals?
I don't know, but I believe it's reasonable to assume that the connector labels matches tables 47 and 50 in section 5.1 of https://www.quectel.com/wp-content/uploads/2021/04/Quectel_RG50xQ_Series_Hardware_Design_V1.2.pdf
Which makes the missing ANT2 and ANT3 connectors exclusive for n79. This supports the theory. The NR7101 does not support n79 according to https://download.zyxel.com/NR7101/datasheet/NR7101_5.pdf
So table 50 should tell you what you need. Just ignore band n79. You'll probably want at least two different types of antennas. One going down to 600 MHz on ANT0 and ANT1 and one going up to 4200 MHz on ANT4 to ANT7.

HI.
This antenna is for mobile ( 3g 4g 5g - LTE signal, should be connected to ANT0 and ANT1 connector, as mimo devic you need a dual antenna, 2 connectors as your link provide... "• Strong MIMO Antenna" )
Connector labelled ANT 4 to ANT7 are for 2.4 and 5ghz signal.
All connectors are U.FL.
- For 3g 4g, 5g signal you will need a connector U.FL to SMA female , as your link say it's a SMA male on this antenna.
- For 2.5 and 5ghz you will need U.FL to what ever your 2.4 and 5ghz antennas replacement comes with.
Caution I don´t know this device, but it make sense by layout the of the antennas ( 2x mimo for 3g 4g 5g signal, and 2 dual antennas for 2.4and 5ghz signal )
Hey! I hope you are right. I am ordering the antenna and u fl to sma cable for testing.
The TOH says wifi antenna is on the main board but i can not see anything that looks like antenna on the main board. I am not going to use wifi so its only LTE antenna i need external.
HI.
Hope so...
Check here. From an South-Africa manufacturer:
https://poynting.tech/marine-coastal-antennas/
I used some of them on RV, for LTE and 2.4g with good results. Not the marine ones.
RV ? Yes i have been looking on this ones before. i tought maybe the Puck-4 with 2x2 LTE would be the best one. https://poynting.tech/antennas/puck-4/
I am not sure what the risk of connecting a wrong type antenna would be?
For me its useless if i cant connect antenna on it. I bought it for this test purpose and hope it will work.
At lest i should be able to connect first on ANT0 and ANT1 and check the diffrense in signals?
I assume it is not high voltage and burns up anything.
HI.
RV, camping caravan, etc... the puck 5 is the one I used. 2.4 and Lte.
Okey, thanks for sharing, i think i will by both a puck-4 and the nedis for testing.
We are sailing far out at sea, so would like the best one for long range LTE also.
Today i am using this https://www.outdoorrouter.com/product/outdoor-mimo-4g-omni-antenna/ and gets LTE signals for about 50NM from shore. I also do have som days in port it would be nice with 5G..
Hi.
The risk is to not connecting any antenna. You can kill the radio.So any antenna 2.4 5ghz LTE connected is no risk. The issue is the signal will be weak. I burnt a couple of radio on milkrotik boards ( LTE and 2.4/5ghz radio ) when the UFL disconnected with strong vibration. Tip: hot glue over the UFL and the board.
HI.
Check this ones to:
MIMO FS3500, from finland
https://www.datakauppa.fi/tuote/fs3500-5g-4g-3g-gsm-mimo-paaluantenni-4-6dbi/
Never tested, but I saw some of them on RV´s all over Europe.

HI.
Update.
I was looking for rg502q-ea specifications, and it may be that all the connectors are for 3g/4g/5g signal. So you may need 3 of theses antennas.
I found this, mikrotik chateaux : https://forum.mikrotik.com/viewtopic.php?t=162363.
And back to your pictures, I can identify trace lines from all the UFLs to the quetell lte modem.
Looks like it will be cheaper to buy a nr5101 and mount in a watertight box with only one dual antenna?! 
Nope, not true. Please check your info before posting. All ANT0-7 connectors all for different 5G/LTE bands.
The wifi antennas are those puny circuit board antennas. This device is designed as a LAN-5G/LTE router, and the wifi interface is just there for configuration.

Look next to the console connector. And there's another one on the other end of the same board edge

HI.
- My answer was corrected 15 hours ago..
- My answer was not an affirmation, It was just a possible combination for antennas layout. It was clear on my post.
- I checked my post and corrected it.
