Electrical tilt is a tilt which gives by knob present downward in GSM antenna.
It is done for effecting the coverage of antenna. If one GSM antenna overshoots then interference will produce.
then we give electrical tilt then front lobe will change and back lobe will not change.
so antenna provides coverage in both direction.
Electrical tilt is always gives in City.
It reduces interference.

What electrical device powers the RFID?
The RFID is powered by its own antenna. When in the presence of a pulating magnetic field, the antenna generates a signal that can power up the RFID, causing it to generate its code on top of that field.
Is antenna passive or active component?
An active antenna is an antenna which has an amplifier attached very closely to it. The antenna/amplifier system is called an active antenna. It is used for receiving signals only. The idea is to set the signal-to-noise ratio (SNR) before the signal travels along a transmission line where it is susceptible to interference and loss.
Why High frequency reduce the size and weight of components?
The concept is, greater the frequency less will be the size of antenna and weight. For example the Mobile Phone uses the half wave dipoles antenna. There is no exact formula for calculating these antennas. The problem is that there are several factors that affect the antenna. Fortunately there is a starting formula for these types of antennas. For center fed, wire dipole antennas, the formula is length of antenna = 468/freq (MHz). Mobile phone in GSM working on the frequencies 900 MHz and 1800 MHz so put the values in the formula you get your answer. If you move further in the frequency band the size will be more small.
How do you convert cellphone gsm frequency to another gsm frequency?

What is a reconfigurable antenna?
an antenna that is able to be formed, or bent
What it is a tilt?
In gsm tilt is a adjustment to control the extent and penetration power of antenna.
What is mechanical tilt in GSM antenna?
The Mechanical Tilt is given by physically tilting down the GSM antenna. Tilting downward focuses the beam on a specific area and hence better coverage.
What is Electrical Tilt in Kathrein Antenna's.?
Technology used in Electrical Tilt antenna is to tilt the beam by altering the signal Phasing,resulting decrease in main,side and backward lobes.This has overcome the shortcomings of Mechanical Tilt Antenna in which the the whole antenna is physically tilted,which lifts the backward lobe in upward direction and sidelobes patterns are somewhat distorted. Now a Days Remote Electrical Tilt Antennas are popular,In which Electrical Tilt can be done from Remote Location.
What is antenna tilt?
Antenna gain of base station for a specific user depends on antenna pattern, antenna orientation (azimuth and tilt) and user's coordinates with respect to base station.
What is frequency used by GSM antenna?
1.25MHz

What is the electrical and mechanical tilt?
Mechanical tilt is given physically but Electrical tilt set by antenna designer for the operater.... If mechanical tilt given the front lobe is directed to the particular location..means toward the H- plane...and back lobe is directed to air..means opposite direction to H- plane...so occur result is the interference in back lobe... If electrical tilt given the front lobe and back lobe toward the H-plane.....so occur result is reduce the interfernce in back lobe...
What can transformation can occur in a radio antenna?
The radio antenna converts electromagnetic radiation to electrical energy
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 do you mean by Antenna Hopping in GSM?
Antenna hopping is a feature in which the Tx/Rx is passed through all the available antenna paths in a sector. No frequency is changed during antenna hopping. This helps improve performance by providing spatial diversity.
If your power antenna on a '91 lesabre jams up but the motor keeps trying to make it go down how can you stop the motor and fix the antenna?
unplug the electrical from the antenna. replace antenna.
