Which antenna goes to which interface?


Recommended Posts

I don't see a topic on this so does anyone know which antenna port goes to which interface?     I'm assuming it's 1/2/3 but is it 1/2/3 left to right or right to left if you are holding it with the USB ports facing down?

Yes, I would also like to know this.  To add to the original poster's question, do  these assignments change if I add the 5Ghz module or other wireless USB adapter (to gain 5ghz)?  Is there a per antenna interface that could give you the SWR of the attached antenna?  I'd like to use different antennas (yagi, patch, dish) for different beam patterns.

ok found this info in another post

stock config

Front side = USB ports + button

I decided to move my antenna's to one side so it's easier to use inside a backpack.  Fairly easy to do, used a 1/4" drill bit by hand (as to not crack the plastic) and small wrenches to tighten the connectors.

That's a convenient way of relocating the antennas. I decided not to alter the original case in any way so I 3D printed an alternative variant instead so that the Mk7 can be restored to stock. Looks almost exactly the same (as the picture) when it comes to antenna positions, but I added an extra "box" on top of the original case that lowers the antennas making it a bit more compact when it comes to height/length. In addition, I also added a bracket for my Alfa ACM external USB 5 GHz NIC so that it all comes together as one unit.

I'm using a very short USB C cable between my "mini ups" (Voltaic V25 battery pack, which has pass through charging) and my Pineapple.  I got it here

Amazon has it listed at 0.5 length about 6"

seems like a good quality cable so far.  You would need an adapter to change gender.  I found these useful also

and these

all are working well for me.

Greetings, Ughcomeon,

Thank you for posting antenna configs.

Need to ask which antenna ports to plug in outdoor antenna(s).  I have one Omni-directional, and a MFJ-1800 directional, each with 10 ft coax and appropriate SMA male connectors.  If I use only one external antenna, which port should I use?

The MFJ-1800 is amazing!   I used to use it to leach IP out of hotel windows, by pointing it to less secure neighbor hotels or toward distant residential neighborhoods.  All I needed was line of sight; distance can be miles away.  That was back in the days when secure wifi was about 50% and there were lots of unsecure APs except in the DC area.

MFJ-1800 Antenna

There is a caveat, the coax needs to be no longer than 10 ft.  I experimented with a 50 ft LMR-400 coax and the db loss was way too high. The USB cable between the computer and the transceiver would have to be as long as USB will function, in order to tower mount the MFJ-1800 and the transceiver.

Many thanks,  for all your hard  work.
