Evening all,

Situation, live on the outskirts of Helensville, just North of Auckland (Far North West AKL)

We did have a 4G /200G connection (RBI), made the move to 3G (RBI) / Unlimited plan. - Heavy Users!

Using a B315 Modem, with a single external antenna  (ANT-205 - 11dBi Wideband LTE Broadband Directional Antenna)

Operating on Band 8 - 900Mhz 

Currently getting approx 7M/2M

Ecio: -9dB
Rscp:-71dBm
Rssi:-62dBm

A few questions.

Does RBI 3G using MIMO ?

If Yes should I purchase a 2nd ANT-205 Antenna to get more throughput ?  

Or do I purchase a dedicated 900Mhz Antenna, with higher Gain was looking at he following.

or

I am leaning towards to the Ant-100 more gain and birds won't bend it!

Anyone else in the same situation ?  I and use the ANT-205 for another project so I am not worried about swapping it out, just don't want to spend $200 on an antenna if it isn't going to make a difference.  

Thanks
