Today's cars have multiple antennas. The car's design does not usually allow these antennas to be positioned vertically in the center of the car roof, although this would provide optimal functionality. A compromise must be made between design and function. This makes it all the more important to test the receive level of UHF digital TV antennas in real-world operation. Up to now, drive tests had to be performed in areas with known receive conditions. Receive levels were usually assessed indirectly, by subjectively evaluating the program quality.

In radio communications , a radio receiver , also known as a receiver , wireless or simply radio is an electronic device that receives radio waves and converts the information carried by them to a usable form. It is used with an antenna. The antenna intercepts radio waves electromagnetic waves and converts them to tiny alternating currents which are applied to the receiver, and the receiver extracts the desired information.

This chapter presents the Voice of America VOA with a roadmap for introducing satellite audio broadcasting technology, and the improved services which it allows, into its operations to compensate for many of the transmission and reception limitations of its terrestrial, high-frequency HF , relay network. The related question of television broadcasting must receive only passing mention at this point, although that medium is an increasingly effective one. There might be merit in assessing the relative emphasis on the two media, but that assessment lies outside the scope of this report for the following reasons. First, the VOA has elected to pursue its informational programs through the audio medium and has not formulated a role for itself in television.

Radio broadcasting is transmission of audio sometimes with related metadata by radio waves intended to reach a wide audience. Stations can be linked in radio networks to broadcast a common radio format , either in broadcast syndication or simulcast or both. Signals can be either analog audio or digital audio. Television broadcasting also uses radio frequencies, but includes video signals. The earliest radio stations were radiotelegraphy systems and did not carry audio. For audio broadcasts to be possible, electronic detection and amplification devices had to be incorporated. The thermionic valve was invented in by the English physicist John Ambrose Fleming.

Dipole tv antenna diy. And while it has proven to be very effective in many instances, it lacks a certain cool-factor. Baluns are usually used to feed dipole antennas with ohm coax and to transpose from ladder line feeding a multi-band antenna to the unbalanced input of an antenna tuner. The gain is related to the range of frequencies and the number of dipoles. I actually get more stations with the new digital television signals than the old system. A "dipole" antenna connected to your radio should work just as well as an amplified antenna If you still use it to receive off-air TV, then get an inexpensive TV-FM splitter. Post Because the DIY bending process isn't completely reproducible, it is best to leave some extra length so that the ends of the tube overlap in the centre when the dipole is folded. The folded dipole antenna or folded dipole aerial is widely used, not only on its own, but also as the driven element in other antennas like the Yagi antenna and various other types of antenna.
