Alfa APA-M04 7dBi Antenna

If you’re a fan of Alfa’s AWUS036NHA USB network adapter, you’ve probably considered picking up an Alfa APA-M04 7dBi directional panel antenna. Although the APA-M04 costs under $8, you’re better off using your hard-earned money to polish your least favorite pair of shoes. I have to admit that I didn’t research this antenna before I bought it. In all honesty, I got caught up in the excitement of ordering an Alfa AWUS036NHA and, when coupled with free shipping, I couldn’t resist spending the extra $8.

When compared against the 5dBi dipole antenna that comes with the Alfa AWUS036NHA, the 7dBi antenna failed to prove itself a worthy contender. To make this comparison, I tested each antenna by performing a 60-second airodump scan in a controlled environment. The test yielded results indicating that the 7dBi antenna is hardly an upgrade. See for yourself.

You probably felt like you were looking at two scans performed by the same antenna. I felt the same way. You may have noticed that the 7dBi antenna’s results reflect a slightly higher signal rating. Although true, the question is whether or not the small increase in performance is worth $8 +shipping?
