Difference between gsm antenna and microwave antenna?
In GSM mainly using Panel type antennas but in the case of Microwave Antenna using Horn antennas. Microwave anteenas propogate signal straghtly. So line of sight (LOS) is main issue in the case of Microwave antenna, it means that both antennas must be allign in face to face. Microwave antennas are using for link between BTS but GSM antennas are directly link with customers. Antenna Gain also very much difference both cases. JPS o,[.[;.;[.]/]/ pppppppppppppppp
What is radiation pattern for an antenna?
Radiation pattern is just a map of how the strength of the signal varies around (transmitting) antennas. For some, like a simple whip antenna, the patttern too is quite simple. For directional antennas they can be quite complicated.
What is satellite uplink?
The uplink is the transmitter than sends the data up to the satellite. This can take the form of a dish or a highly directional antenna. You typically see these directional antennas mounted on telescoping poles mounted on the top of TV station news vans.
What is the Application of Rhombic antenna?
dipole antennas evolved antennas ground anteena
What is the difference between directional and non directional over current protection?
The directional part. Directional relays will operate for events "in front of" them, but will not operate for events "behind" them. Typically directional relays are used in non radial situations such as on the bulk electric system. Non-directional overcurrents are commonly used on radial lines.
What do cellular networks use directional antennas to form?
a network of cells
What type of antenna using in mobil bug?
omni directional antennas
Which WiFi router is best in a building?
a MIMO router with omni-directional antennas, perhaps with higher gain than stock antennas.
What antennas used in wireless technology?
three basic types of antennas are: omnidirectional; semidirectional and highly directional antennas. typically when you purchase wireless access point and wireless NIC it has attached 2.14dbi omnidirectional antennas

What two types antenna used for terrestrial microwave communication?
Virtually all terrestrial microwave communication is point-to-point, using parabolic reflector antennas. A small percentage uses yagi, helical, corner reflector, or flat-plate reflector antennas. Essentially no "omnidirectional" antennas are used in microwave.
What connection type uses two directional antennas to make the wireless link?
802.11g
True or false highly-directional antennas are generally concave dish-shaped devices?
true

What is the difference between omni directional and directional antennas?
An omni directional antenne receives or transmits signals from all directions as in 360 degrees. A directional antenne is aimed in a specific direction so that it may direct an outgoing signal to or receive a signal from a specific source.
