Geplaatst: 10 nov 2018, 11:30
Here's how the SteppIR UrbanBeam compares to a 5 band (20m-10m) G3TXQ Broadband Hexbeam. Free Space, no additional transmission line loss for either model. The green dot caption in the upper-right corner of each frame in the animation shows the gain difference between the two antennas. Frequency is shown in the lower-right corner. 40m/30m for the UrbanBeam not included.
