Is the Harvard Engineering antenna really omnidirectional?

In the last video we looked at comparing the gain of the Harvard antenna to a simple dipole and to my tin foil cantenna. But some people claim the Harvard antenna is directional, that is that it will effectively transmit a higher signal in one direction. So in this video we move the antenna around 8 compass points, that is a 45 degree change, and for each compass point we measure the received signal strength. There is perhaps 1dB or so variation, which is accounted for my the non-uniform shape of the groundplane on the antenna and by the cable moving around when the antenna is moved. But as there is no large increase in an direction, we can conclude that the antenna under test is not directional. In order to make it directional I stuffed a bit of old microwave lid behind it and that instantly gave us about 3.5dB of gain. As far as I know, no street lights have bits of old microwave or any other reflector on them. Here is a video by an actual antenna expert about this same antenna:    • Mark Steele and his Magic 5G Antenna   And my previous video comparing the gain of this antenna to some others:    • Antenna Comparison - Street light antenna ...   MCToon revealing that Mark managed to epically troll himself:    • Anti-5G scammer Mark Steele, gets HUMILIATED   And MCToon when Mark surprised him by popping into a debate, a bit hard to watch, but very very funny!    • Anti 5G Campaigner Mark Steele Gets Everyt...
