Razor512 Posted November 2, 2011 Share Posted November 2, 2011 (edited) On a recent episode of hak5 (10x11), Darren was using a yagi antenna but I noticed one issue. it looked very close to those found on ebay, and I have actually purchased one a long time ago which looks the same. But there was an issue, It performed significantly worst than the coat hanger + cardboard yagi that I made Then I also noticed why, the driven element, as well as the boom and reflector and parasitic elements were all more or less linked and conductive with each other, essentially turning the entire frame into a large antenna. Which poses another issue of the irregular shape no longer being tuned to 2.4 GHz This caused a very low gain and the antenna performed better pointed straight up functioning as a omnidirectional antenna rather than a yagi (directional) It also, regardless of how well I aimed it and regardless of direction, not get anything better than -90 -85 signal for the open access point for the near by coffee shop, but with a 5dbi omnidirectional antenna , I can connect with a signal in the -70 range. PS, I was able to get a refund on the antenna. Has Darren done any testing with his antenna to see what kind of gain it actually gives? I am interested in seeing what kind of gains he is actually getting in order to see if I should probably try getting another Edited November 2, 2011 by Razor512 Quote Link to comment Share on other sites More sharing options...
