radial

Radial (radio)

In RF engineering, radial has two different meanings, both referring to lines which radiate from (or intersect at) a radio antenna.

The use of the radial method is more common in North America, where the FCC and CRTC use it in mediumwave transmission planning and regulation. In Europe and Asia, the use of radials has fallen out of favor since the 1970s, and in many nations the radial antenna proof is only acceptable as an ancillary antenna proof. Canada and Mexico, due to lower population densities, never implemented the fully complete radial models that the US FCC did.

The radial method has been falling out of favor for methods based on Cartesian coordinates. Cartesian methods require more CPU time (and memory) to compute, but are understood to more realistically represent antenna systems. The main importance of the radial methods is that a quick antenna system proof can be completed in less than 15 minutes (often in only 5 minutes) of a typical home computer's CPU time, regardless of antenna system complexity.

The ITU over the past 50 years—in consideration of the various population densities of its members—officially mandates a minimum of 5 radials for an entire antenna system.

The geometry is entirely radial, so there are no edge-bleeding effects, and, as far as I can tell, the thing is distortionless, intertialess, and self-interference-free, so that anything stored on it will last until the end of time, or until quanta-level decay erodes the fundamental substructure of the behavior of basic particles, whichever comes first.
