2nd, two whip antennas. Not only did it not improve signal strength, speed test showed a 20% drop in data transfer speed.
Talked to the smartest electrical engineer I know, he said even with the short (12") coax, the signal loss on that cable may overcome any advantage I might get out of the antenna.
This.
I'm not a EE and I'm not an antenna engineer.
But there's a Youtube nerd I watch regularly that will occasionally test antennas with his gear and a spectrum analyzer.
It's painfully clear that most attempts to mod ("improve") the antennas on an off-the-shelf piece of gear will likely make things worse.
I've had two good successes in increasing range. First was to take just the outside antenna that shipped with the Alfa Camp Pro and plug it directly into my laptop. That's a nice outdoor antenna with good dB gain.
The second was to take a decent Asus router (RT-AC3100) and use it as a range extender. It's pretty good.
