What is necessary to use an analog television for viewing over-the-air (OTA) digital television (DTV) programming? - ANSWER An external DTV tune...

The MIMO antenna depicted in Figure 28 is constructed by joining two monopole antenna elements, which are placed side by side, at a distance D from each other, with a separate ground plane. As the ground plane is very compact, surface current and near-field radiation cause strong mutual coupling between the two antenna elements, resulting in signal interference that limits the effectiveness of the MIMO system. In order to improve the insulation while maintaining a compact size, we used an approa...

Antennas are divided into two basic classifications HERTZ Antennas (half wave) MARCONI Antennas (quarter wave) HERTZ Antenna operating frequency 2MHz and above MARCONI Antennas operating frequency Below 2MHz 4 basic characteristics of antennas Reciprocity Gain Directivity Polarization The ability for an antenna to use the same antenna for both transmitting and recieving Antenna reciprocity The measure of an antenna's ability to focus the energy in one...

Customer premises - Correct answer-Connected to the network through distribution taps spliced into the coaxial cable. Branches in the architecture - Correct answer-The downstream signal is distributed within nearby neighborhoods using 0.412-inch to 0.625-inch diameter coaxial cable, splitters, and directional couplers. Bridger amplifier - Correct answer-A portion of the downstream signal is boosted before being split and routed to as many as four separate coaxial cables—the branches in t...
