Hi there,

I want to use an RB751G-2HnD as a router and as an access point.
I can't find the right pigtail, connector for the external antenna.
Can somebody help me?

on ebay here its called MMCX. Here is Common Wireless Antenna Connectors

Thanks for your answer!
I tried to use an angle pigtail cable on the RB751G-2HnD but it doesn't fix on the connector!
I need a straight cable. Does it exist?

Yes, they exist. The rb751g i have works with the angled though, as the mmcx protrudes from the case.

Why they didnt use an Resma though.

I'm using this cable (see attachment to this post).
Is it possible to use only two adapters without a long cable between the two connectors?
