LB1120 Antenna Options

[pbking2010]

So I have wahoo internet and I use the netgear lb1120. I have a very weak signal, mostly 1 bar sometimes 2. I found this youtube video of an antenna for it and it seems like they were probably in the same situation as me. They used a wilson wideband antenna and seemed to gain about a bar. Is there something that would be more effective? Here's a link to the video referenced. https://youtu.be/VYSKHzYCt0Q  Thanks in advance.

How much did your signal improve with that setup?
