Rakshith,

We do not provide reference designs or align ourselves with specific antenna suppliers, this is because our distribution partners hold many different and opposing lines so it would be wrong of us to push one over another plus what one antenna supplier might supply would be good for one customer but not for another.

All we can do is provide a specification of what the unit needs to see to be able to operate correctly after this the performance is down to the antenna and customer requirements.

Having said the above I have customers using Taoglass antenna very successfully and I use them myself sometimes.

Regards

Matt
