I think the question needs to know how to increase signal strength from Receiving Antenna.
1. Use Better and bigger Ground. This will not only increase signal but will also increase S/N ratio.
2. Generally increasing the size of antenna helps.
3. Use elements that can increase the effective area of the antenna.
4. Ensure that the antenna is well matched to the feeder feeding the RF signal.

Why does a digital tv keep randomly losing it's signal?
weak signal strength. Call up the signal strength bar from the menu then raise or rotate the antenna until the bar shows an increase.
What happens if you increase the current in an electomagnet?
As current increases, the electromagnet strength will increase.
What is a piece of equipment made of wire or long straight pieces of metal for receiving or sending radio and television signals?
This might be a description of a radio antenna.
How is the radiation pattern of a parabolic reflector antenna plotted?
The paraolic antenna has a high degree of "directivity" compared to many other antennas. That gives these puppies big gain. But they need to be pointed in the "right" direction to work well. This antenna design is used in many radar (and other microwave) applications, as well as in satellite communication. And is has a home with radio astronomers, too, but they're usually listening instead of transmitting. It has a parabolic reflector, and some kind of support for the feedhorn, sub-reflector or whatever is at the focus. We're talking about a transmission antenna here, so there will be some kind of feed assembly to put the signal onto the parabolic reflector to "send out" or transmit that signal. How do we test it? It's so simple that you're not gonna believe it. The reflector can be modified a bit to "broaden" the primary lobe of the radiated signal either horizontally or vertically. But let's work with a simple parabolic reflector. Imagine a parabolic antenna that is fixed so it's stationary. Let's look at which way the signal goes. There are two variables to assess when plotting the radiated pattern, and they are usually referenced to the "direction" or "directivity" of the antenna, or the direction of what might be termed the primary lobe or beam of the radiation. Put another way, there is one direction that is the "center of the beam" for this antenna, and once we establish this line, we reference to it. Something is either left or right of the line by "x" number of degrees, or something is above or below the line by "y" degrees. You gonna put this up on a pole and walk around measuring radiated power at different points left or right of, or above or below the beam? Remember I said this was ease? Put the antenna on a stand and make it point horizontally. Make that stand like a heavy duty lazy susan so the whole thing rotates. Hook up a signal generator to it, and put in the desired operating frequency. (The signal generator won't be generating high power, and that's okay. A milliwatt isn't even necessary for the test.) We're now ready to transmit, and that's our test antenna setup. Step off a hundred meters (or whatever) and set up a receiving antenna (pointed at the antenna under test and at the same level). Hook up a receiver to the receiving antenna so that signal strength can be measured. Turn on your equipment and rotate the turntable slowly. As the turntable rotates, it causes the antenna being tested to "sweep" the horizon with its little output signal. As it moves around, the receiver will be getting more and more and more signal, or less and less and less signal, depending on whether the test antenns is sweeping toward or away from the receiver. With a computer hooked up to the receiver (via a handy IEEE bus) and doing some recording, a relative signal strength can be plotted. Presto! You've got a 360o plot of the relative output signal strength. All you have to do is raise you receiving antenna a touch, and then point it down a tiny bit so it's aimed directly at the test antenna. Then turn the test antenna and record for another 360o view at a bit high of beam center. Keep moving up the receiving antenna in steps, realigning it, and testing a circle. Do this for a bunch of vertical levels above beam center. Then come back and do it again for a bunch of levels below beam center. You're done! The trick is to set up the test antenna on a turntable and point it flat out and level with the horizon, and then to begin with a receiving antenna level with and pointed directly at the test antenna. The turntable does most of the work, and it makes it easy. The work is in raising or lowering the receiving antenna in calculated steps and realigning it at each step to point it directly at the test antenna. By the time the test crew get finished, the computer can plot a nice 3D chart (in the form of a thick cylinder with the test antenna at the center that will demonstrate the performance of that test antenna.

One day receiving all channels on antenna next only Chs 6 12 and 40 Not a weak signal NO signal as if there is no broadcast from station Converter box amplifier and TV work fine.?
Try rescanning the set. Did the antenna get turned to a wrong direction?
Does a signal being transmitted from an antenna to a receiving antenna lose strength exponentially?
Yes.
Will putting an antenna booster on my antenna actually help or not?
Claims made by antenna booster manufacturers are often exaggerated. With that said though; studies have shown that antenna boosters will help to increase signal strength somewhat.
Does a cell phone antenna increase signal strength?
I believe it does. Most new phones have built in antennas that aren't visible. On older models you have to put out the antenna yourself. This helps on older models.
Why does a digital tv keep randomly losing it's signal?
weak signal strength. Call up the signal strength bar from the menu then raise or rotate the antenna until the bar shows an increase.
Is the receiving antenna radiate radio wave during reception?
A receiving antenna does "re-radiate" some of the power it receives, but not all. Some of the power it receives proceeds into the receiver ... which is the only way we detect the signal being received by the antenna.
What is longwire?
It's a type of radio signal receiving antenna
What is the difference between transmitting and receiving antenna?
There is no difference between the two.
How you can inceares efficiency of antenna?
Height, direction, antenna type and down lead are major factors in receiving a good TV signal to the TV set.
Show that doubling the transmission frequency or doubling the distance between transmitting antenna and receiving antenna attenuates the power received by 6 dB?

How wireless computers understands radio waves?
As computers have receiving antenna with resonating sensors.
How do you increase the range of an internal wireless LAN PC card?
For internal wireless adapter there is no way how you can increase the range. But you have an internal card with removable antenna you can replace the antenna with that one which has a cable attached to it and bigger antenna. Varying position of the antenna you can get find a position with stronger signal.
How does the frequency of an electromagnetic wave compare with that of the electrons it sets into oscillation in a receiving antenna?
The frequency of an electromagnetic wave must be very high to release electrons. The electrons that it releases are set into oscillation in a receiving antenna must by definition have a lesser frequency.
