Log Periodic Antennas for the Radio Amateur Elk Antennas was started to give the Ham the best Log Periodic antennas with the best gain, directivitiy, and front-to-back ratio possible for the size and price. We offer assorted millimeter wave antennas up to 325 GHz including cassegrain, conical horn, omnidirectional, rectangular horn, and sector antennas. For an omnidirectional antenna, if the antenna gain increases by 3 dB, the antenna length will double. Browse Motorola's selection of mobile radio antennas and find roof-mount and through-hole mount antennas for cars and motorcycles, to support your two-way radios. Our antenna patterns reveal gain and directivity. It is a versatile antenna with 360-degree coverage, having a gain of 4 dBi at 2. DualBand 2M/440MHz base antenna The GP-9 is the highest gain, dualband fixed station antenna available from COMET. First of we need to understand what the dBi value of an antenna means: “The decibel (dB) is a logarithmic unit of measurement that expresses the magnitude of a physical quantity (usually power or intensity). The Fullband® MIMORAD 4G Antenna is a high gain, outdoor Radome MiMo antenna providing a supberb Omni Directional antenna solution with twin antenna cables and SMA connectors to connect to our range of 4G Routers. In a transmitting antenna, the gain describes how well the antenna converts input power into radio waves headed in a specified direction. TV FM High Gain Mast-Mount Antenna UHF/VHF/FM Amplifier with Switchable FM Trap. Specification for LOWE's GPS Antenna with low noise amplifier. Radio Propagation Vol. Model # Band Stacked Element Phasing/ Wavelength Gain/dB Watts Connector Type Weight Lbs. Antenna gain is the ability of the antenna to radiate more or less in any direction compared to a theoretical antenna. The antenna has an adjustable elbow that allows you to position the antenna vertically on base scanners. parabolic antenna gain. Antenna pattern. antennas? Cables and cable connectors induce signal loss, while antennas are designed to introduce signal gain. Antenna Gain: A relative measure of an antenna's ability to direct or concentrate radio frequency energy in a particular direction or pattern. Free* SI International, Norman, OK Nita K.
