As a consequence, players at a skill level just below the floor would only be on the rating list if they were overrated, and this would cause them to feed points into the rating pool.

Patch antennas can easily be designed to have vertical, horizontal, right hand circular ( RHCP ) or left hand circular ( LHCP ) polarizations, using multiple feed points, or a single feedpoint with asymmetric patch structures.
23.
If the feed point is distance " x " from one end of a half wave ( " ? " / 2 ) dipole, the radiation resistance relative to the feedpoint will be given by the following equation.
24.
If the conductor is of a wavelength long, current from the feed point will undergo 90 degree phase change by the time it reaches the end of the conductor, reflect through 180 degrees, and then another 90 degrees as it travels back.
25.
In these designs, the reflective surface is created by the end of a conductor, normally a thin metal wire or rod, which in the simplest case has a " feed point " at one end where it is connected to a transmission line.
26.
You can make an assymetric sheet out of Teledeltos paper ( paper treated chemically to give electrical conductivity with a definite resistance per square ) with regaularly spaced longitudial copper strips-make sure the strips approach but do not touch either the copper test sheet and and the feed point.
27.
In case the transmitter has TEM or quasi-TEM output connections, instead, a dual-polarization antenna often presents separate connections ( i . e . a printed square patch antenna with two feed points ), and embeds the function of an OMT by means of intrinsically transferring the two excitation signals to the orthogonal polarization states.
28.
Installing the tuner between the feed line and the antenna allows for the feed line to see a load close to its characteristic impedance, while sending most of the transmitter's power ( a small amount may be dissipated within the tuner ) to be radiated by the antenna despite its otherwise unacceptable feed point impedance.
