Incoherent isotropic radiator

WebAug 31, 2024 · Obviously you can have 2 or more radio receiver channels connected up provide diversity. Making a dipole shorter does make it more isotropic, but at the expense of efficiency and/or bandwidth. I think its possible to make a quadrifiller helix fairly isotropic. You end up with a single null at the feedpoint though. WebSep 24, 2013 · It has long been conjectured that isotropic radiation by a simple coherent source is impossible due to changes in polarization. Though hypothetical, the isotropic source is usually taken as the reference for determining a radiator’s gain and directivity.
