i am trying to increase my internet reception at a construction site i use the verizon mifi hotspot.....
will an antenna, or those other devices, they advertise really work?.... or are they just another way to seperate me from my money?
You will get better results with an external antenna for your model, which will increase range, local speeds, and signal strength. THIS is a decent one, but there are high end units available for more permanent mounting.
