I have the Telstra Sierra 320U Aircard and purchased the 107cm external COL2190 Cellular Antenna with patch leads. I have mounted the antenna and attached the path lead to the end of the antenna cable and then on to the 320U.
MY question is; does it need to be in a particular slot or can either slot be used.
The reason for my enquiry is that it is supposed to be a 6.5dBi boost and yet I see no difference in the signal and certainly do not get the green 4G light despite being within the 4G coverage area.

Thanks for your input re the antenna slot.
I am literally right on the line of the 4G and the blue 20 Mbps to the north of wollongong. Was hoping the antenna would help drag it in so to speak.
I know this is an old thread, but still very relevant, and I feel that the issue was not really solved.
Re: the COL2190 antenna.
It might be 6.5dBi on nextG 850MHz but Im guessing its gain is more like 3dBi on 1800MHz, I could not find any data online for the COL2190. So then theres the coax , if your using RG58 or even LMR200, that 3dBi may be 0dBi by the time the signal gets to your modem.
Now , if you have Line of sight to the 4G tower you would be much better off using a Yagi Antenna designed for 4G 1800MHz.
Ive installed a few of these with fantastic results: on 4G LTE:
