deflection members with the electrons in the beam passing between those members in structure 10 the sections of the meanderline formed by plate segments 60 are of relatively low impedance because of their relatively large width while the sections formed by the interconnecting strips are of much higher impedance the strips 61 thus perform the additional function of raising the average impedance of the line to a value that can be driven economically by way of explanation vertical deflection signals in modern high frequency oscilloscope crts are provided by transistors which are basically current sources by maintaining a higher line impedance a given deflection voltage can be obtained with less input current this allows the use of less expensive transistors and reduces overall costs integrally joined to the laterally outermost extent of each interconnecting strip 61 is a mounting portion 67 portions 67 which are significantly wider than strips 61 suitably about twice as wide are directly joined to glass rods 52 for support of deflection member 50 in vertical deflection structure 10 referring now to fig1 and 4 it will be seen that in the completed deflection structure members 50 are disposed with their plate segments 60 in spaced mirror image opposition the interconnecting strips of each member angle away from those of the opposite member suitably at about 45 u00b0 from the horizontal in the exemplified structure so that the.
