I snagged an Alienware Alpha for a great price, but unfortunately it had extremely poor reception where I located the unit, to where I did not have a consistent signal. I removed the built in antennas from the unit and positioned them outside, which helped somewhat, but still not good enough.

However, I had recently purchased a Monoprice Maker Select Mini... a solution presents itself. I ordered two 15cm MHF4 RP-SMA pigtails, and some antennas from an old dual band router, and here we are. Signal is vastly improved - where the stock antennas had no reception, I've got rock solid reception.

Parts

• Pigtails. Anything similar should work so long as they are MHF4 and at least 15cm/6" long.
• Antennas. Not the exact ones I used, but same rating. Ensure if you pick your own that they are dual band - I tried some old 2.4ghz high gain antennas and got very poor 5ghz reception.

Installation
Run the pigtails through the bracket's hole, through the bottom casing's holes, and finally through a vent hole on the internal chassis. Stick the bracket on top via some double-stick foam tape.
