What is a Yagi-Uda antenna?
how to measure the length of elements and spacing of elements
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 a Yagi antenna?
A yagi is a directional antenna consisting of two or more dipoles.
Who invented tv antenna and when?
the inventor of the antenna was Alexander popov
Why is impedance of a transmission line an important factor with respect to matching out of a transmitter into an antenna?
The impedance of a transmission line (Zo) should be matched from the source of the RF into the antenna. A bad match results in loss of output power and RF reflections up & down the transmission line. Standing Wave Ratio (SWR) meters are available to measure these reflections and enable them to be tuned out. Adjustment of antenna length for best SWR (1:1) is common. More mathmatical approaches are available on the web.
What is the frequency range of a six foot dish antenna?
The size of the dish isn't as important as the length of the antenna. The antenna is INSIDE the little can at the focus of the dish. The length of the antenna is tuned to the wavelength of the frequency being received.
What is principle of lens antenna?
The principle of the lens antenna is THE EQUALITY OF THE PATH LENGTH.
Where did the antenna go in modern phones?
Modern digital cordless phones use high frequencies - the length of the antenna is so short at these frequencies that its whole length can be incorporated inside the casing of the phone. The length of the antenna is 300 divided by the frequency.
Claculate the length of the dipole antenna at 450 MHz?

How do you check to see if your antenna is too short?
A short antenna causes higher than normal current to capacitive reactance and a long antenna causes higher than normal current to inductive reactance; a correct length antenna is free of reactance and appears as a resistance. Change the length of the antenna in small increments until you obtain the lowest (resistive) current.
Can you extend the antena wire?
You can extend an antenna wire, but the added length will reduce amplitude of received signal. You may need an in-line amplifier depending on the application and length of antenna wire.

What is thin linear antenna?
A thin antenna has nothing to do with the physical size of the antenna. Any antenna whose length is less than (1/10) of the wavelength of the signal is thin antenna. A linear antenna is one in which the current distribution is linear or bears a linear relationship with some parameter, say voltage of the antenna...... Mukesh
Why won't the antenna go up on a 1989 Oldsmobile Ninety-Eight?
In the trunk ,on the right side there is a 3"diameter at the base of the antenna wheel that carries the nylon string or rope that winds up the antenna. That has to be replaced...

How long is NBA basketball court?
94 feet is the "optimum length" cited at nba.com.
What is an Antenna Coupler?
For every frequency there is an antenna that is perfect for radiating at that frequency. Unfortunately, it would be unrealistic to carry a separate antenna for every frequency that a communications center is capable of radiating. To overcome this problem, we use ANTENNA TUNING to lengthen and shorten antennas ELECTRICALLY to better match the frequency on which we want to transmit. Simply put, the antenna does not physically change length; instead, it is adapted electrically to the output frequency of the transmitter and "appears" to change its physical length. Antenna tuning is done by using antenna couplers.
What makes metal a good radio aerial?
A good material for an antenna is copper wire. For perfect reception, the antenna should be cut to a length determined by the frequency you want to receive. length = 468/frequency in megahertz.
