[Hackrf-dev] Finding the Interference with directional antenna?

[Scott Davis]

There are many, many commercial directional antennas available for the 2.4 GHz band.  Dish Network operates in the Ku-band, around 12 GHz, so their dishes are a bit small for 2.4, but it sounds like fun to play with one…it’s a lot easier to use a smaller, lightweight yagi.  They come in all sizes.  Here’s one example:
