can someone tell me what is this connector.. I try find on ebay , but cant find 
.
and, do I need 2 pigtails or 1…
needed that to use my RB951-2n as “client” to 1km distance , so cant do it with internal antenna
it is a test point for factory equipment. You can’t connect an antenna there.
too bad 
, nvm will use that router for something else then 
but if there is way to solder somewhere on board connector , or 2 wires for external antenna I will try it , just show where
The only way - buy rb751
have rb751u-2hnd , but., find this rb951-2n cheap so get 2 of these for testing…
and external antenna :
not so big difference, but… if put directional antenna will be better
That’s a really bad idea…
Not bad idea at all. The only drawback is that he cannot call for guarantee.
mxfull it is strange you did not achieve better signal gain. What antennas you connected to the device?
