Due to my work I got interested into WiFi Spectrum Analysis. I got for myself a refurbished kit from my local Cisco supplier. The kit contains a Cisco AIR-AP3602E Access point and a AIR-ANT2566P4W-R= Dual band patch antenna. I decided to go for an indoor/outdoor antenna, which I might use next year (for outdoor grill parties). I think I will start my Spectrum Analysis (looking for Microwave oven, Channel interference, ...) next week and share my experience.
