On his early evening arrival in Israel, he gave a half wave upon exiting the airplane and braved the breezes that almost blew off his white skullcap.

Half wave folded dipoles are often used for FM radio antennas; versions made with twin lead which can be hung on an inside wall often come with FM tuners.
13.
The water cooled copper electrodes remove the surface heat quickly, accelerating the solidification of the metal, since copper is an excellent half-wave direct current, or high-frequency half wave direct current.
14.
The basic design of a photoelastic modulator consists of a piezoelectric transducer and a half wave resonant bar; the bar being a transparent material ( now most commonly fused silica ).
15.
A major practical drawback to this band is that because of the length of the waves, full size resonant antennas ( half wave dipole or electrically short, a small fraction of a wavelength long.
16.
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.
17.
Although there is no wavelength dependence to this dimension in the transverse direction, in the direction of propagation it is necessary to have a minimum of one half wave of conductor length to full support the propagating mode.
18.
By differentiating the full and half wave signals, the doorbell is able to function as it does in the previous wired case, while also providing continuous power to the doorbell for other purposes, such as receiving wireless doorbell button input.
19.
In December 1934, WLW cut back to 50 kilowatts at night to mitigate the interference, and began construction of two shorter towers a quarter wave length high, a half wave length apart, and 1850 feet ( 560 m ) southwest from the main tower.
20.
The " L "-network using only capacitors will have the lowest loss, but this network only works where the load impedance is very inductive, as occurs with a small loop antenna or a straight-wire antenna that is between a quarter and a half wave long.
