Question on repurposing nanostation m5 antenna.

Hello friends,

I have several nanostation m5 devices and I would like to repurpose the antennas they have for the 5 GHz band.

The problem is that, as can be seen in the photos, they have two feed points (marked in red).

This makes me think that they are fed like two separate antennas to transmit and receive simultaneously.

So my questions are:

Can I use the as single antenna?

Where should I feed my signal?

Any help will be apreciated. Thank you very much for your support.

The Ubiquiti NanoStation M5 all-weather access point is a successful solution for transmitting traffic at a speed of 150 Mb / s over a distance of up to 15 km and a frequency of 5 GHz.

Frequency 5470-5825 MHz

Antenna Built-in 2x2 MIMO (4.9-5.9 MHz)

Gain 14,6–16,1 dBi

Polarisation vertical and horizontal

Cross-polarisation> 22dB




A single antenna can be used, either with horizontal polarization or with vertical polarization.

Hello Mr. Admin,

Thank you for yor fast response.


What I'm trying to do here is to cut the traces coming from the pcb and feed my own signal (eg. from a wifi dongle). There's where questions arise.

Where should I feed my signal? Using just one feed point or both?

Can I completely remove the antenna from the pcb or maybe it needs the ground plane to work?

Can I add my own ground plane with a metal sheet?

The idea is to give new life to the antennas, if possible, because this is discarded equipment.


Thank you.
