The following is a listing of affiliates for Antenna TV, [1] a classic television network, which was launched on January 1, 2011, by Tribune Broadcasting [2] and is now owned by Nexstar Media Group. [ 3 ]
The commercially available B&W AC3-30 and B&W DS1.8-30 antennas [6] vary from the above to cover 3–30 MHz using a 90 foot length with an 18 inch spacing of the wires. The balun is a 16:1 ratio, thereby transforming the 50 Ω (ohm) coax to an 800 Ω feed at the antenna.
KDNL-TV debuted on June 8, 1969. Its program schedule was dominated by syndicated reruns of former network shows as well as a daytime financial news program, TV 30 Financial Observer. [28] [29] Channel 30 was the first station built by the newly formed Evans Broadcasting Corporation, which had plans to start activating additional stations. [30]
The system consists of a master antenna and a matching transformer to match the balanced antenna with unbalanced cable and amplifiers. [5] Most antennas have an impedance of around 300 Ω. To convert it to 75 Ω, a matching transformer (or balun) is used. For trunk line isolation, a resistive inductive device known as a splitter is used.
This article provides a summary description of many of the different antenna types used for radio receiving or transmitting systems. This summary article collects groups of antennas based on their electrical operation. The classification and sub-classifications below follow those typically used in most antenna engineering textbooks. [1] [2] [3 ...
Small antennas of any kind are inefficient, but when a full-sized antenna is not practical, making a small loop with a perimeter as close to 1 / 2 wave as possible (although usually no more than 0.3 wave) makes the small loop better for transmitting, although it sacrifices or outright loses the precise "null" direction of smaller small ...
In a C-band antenna setup, the transmission frequencies are typically 3.7–4.2 GHz. By using a local oscillator frequency of 5.150 GHz the IF will be 950–1,450 MHz which is, again, in the receiver's IF tuning range.
At frequencies above 30 MHz an automobile or aircraft body makes an adequate ground plane, [20] [21] so whip antennas for two-way radios and cell phones are mounted on car bumpers or roofs, [8] and aircraft communication antennas frequently consist of a short conductor in an aerodynamic fairing projecting from the fuselage; this is called a ...
