@Exposure Yes, that's for each antenna & yes they are 50 ohms each. But remember you don't add the 2 antennas gains together, because the inputs are separate data streams (MIMO) into the modem as...

@Exposure They are about >1 - 1.5dBi John vk3hjq

I thought you said it was only working on 1 antenna, & that was your problem in the 1st place. Now for this Question .....For this to happen (& it can) the signal strength must be very high, i.e you...

@SujitKrSahoo Yes, for best results both antennas MUST be connected. 1 external antenna only & 1 internal antenna will work but usually in Non - MIMO mode, (if the signal to internal antenna is low)...

@SujitKrSahoo The reason it will not work is because it defaults to Non-MIMO mode if only 1 antenna is connected (AUX) but it will work in Non-MIMO mode if the (Main) antenna is connected. MIMO mode...
