Hi, I want to build a portable antenna for 20m. This antenna will be installed temporarily at a low height, around 3m above ground (10). Ive modeled two antennas in MMana-GAL and compared their gain
If the Jungle-Job is horizontally polarized, you're kidding yourself if you think there is any significant difference in takeoff angle if both antennas are at the same height above ground. 73, Dave A
The Jungle-Job appears to be a horizontal antenna which would make it a cloud warmer at that height. Are you sure this is modeled correctly? You probably would be better off using two verticals, one
At 10°, the Jungle Job still has 7,4dBi gain, while the Moxon shows a -2,3dBi loss This is just a modified 2 element Yagi. Nothing that will magically give it good low angle radiation. I modeled a d
Hi All, I received many comments about this. Thanks for your inputs. First I need to say that, in first place, if I shared my results here, that was because I found them interesting if not disturbing
