An omni-directional, collinear, vertical base station antenna having an adjustable or variable radiation beam tilt capability. Terminations at the drive or feed points are provided by an adjustable, capacitive coupling structure at the feed points between the conductive elements of a feed structure and a radiator assembly for adjusting the physical position of the feed points and thereby the phase of the feed points relative to the upper and lower portions of the antenna to alter the deflection angle of the radiation produced. A signal feed, having first and second conductive feed elements, is connectable to a signal feed line to couple a signal between the feed line and the radiator assembly. An adjustable support and control mechanism supports said elongated radiator assembly and said signal feed for relative movement therebetween to effect selective adjustment of the feed points of said capacitive coupling structure along the length of said elongated di-pole radiator assembly to thereby effect adjustment of the beam angle of the radiation pattern.

Adjustable beam tilt antenna

Electronic sensing and measuring equipment for accurately measuring the pitch of musical sounds and which includes an audio tuner responsive to the fundamental frequency of a continuing signal while rejecting all other harmonically related components of said signal to produce a digital signal representing the fundamental pitch of said musical sound, and a counter for counting and totalizing said digital signal defining the same in terms of its frequency and for visually displaying said defined signal.
