active antenna การใช้

• Other examples include : Power over Ethernet, active antennas, low-noise amplifiers, and down converters.
• It comes with a driver airbag, pretensioner seat-belts, headlight height adjuster, and active antenna.
• They all have AM radio ) the mast itself may be the active antenna element.
• Amateur radio operators have achieved good LF reception using active antennas with a short whip.
• To ensure optimum off-the-air signal pickup, I used an active antenna from DX Antenna, Japan, which I had bought earlier.
• The necessary mission systems and components including the dummy AAAU ( Active Antenna Array Unit ) are successfully fitted onboard Embraer EMB 145I aircraft.
• In 2013 Parsec announced the introduction of a new line of active antennas and module products for GPS / GNSS, M2M and IoT wireless and mobile markets.
• If the mast itself is an active antenna element the ground can be covered by a mesh of wires or metal elements to create a reflecting ground.
• Most active antennas use antenna parts of minimal conducting area, e . g ., a small whip, connected to the active component ( usually a FET ).
• For electromagnetic linear sources, the principal early advances in computer modeling arose in the Soviet Union and USA when the end of World War II and the Cold War were fought partially by progress in electronic warfare, including the technologies of active antenna arrays.
• The advantages of an active antenna compared to a passive antenna and a separate amplifier is that the ( low ) signal can be amplified before it is subject to loss and / or interference in the cables and connectors between antenna and amplifier.
