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.

WebJul 17, 2024 · in free space, a dipole is not isotropic: it radiates in a fat, 3-dimensional "figure-8" pattern with two lobes. the "null point" where the radiation goes to nearly zero corresponds to the direction along the length of the dipole i.e., very little energy is radiated away from the ends of the dipole..
