The actual numbers are not as important as the knowledge that generally speaking, the larger the antenna the more gain it will have. Three other main factors are the Distance from the transmitting antennas are from your location and the Height of your antenna above the ground and what Obstructions there might be between the two antennas.
What else can I help you with?
Up to which frequency does the gain of an antenna increase as the frequency increases?
In general, an antenna is "cut" or "built" for one frequency, or for a band of frequencies centering on one particular frequency. This antenna will respond to all frequencies, but will only exhibit "maximum" gain at one frequency. Frequencies higher or lower will not be received quite as well, and the farther from the "tuned" or "center" frequency the signal is, the less gain the antenna will provide on that frequency. As we work with an omnidirectional antenna, we can "tinker" with it a bit in an attempt to get it to work with a broader range of frequencies, but as we broaden the usable spectrum over which it will work, we will see less gain on the "center" frequency. If you're getting the idea that tuning an antenna involves trade-offs, you're getting the right picture. No improvements are possible without "cost" in another part of the operating spectrum. If we move to a directional TV antenna like, say, one of those antennas (not the dish) that still can be seen on some rooftops, we see what is basically a modified log periodic antenna. This antenna will generally be "pointed" or "aimed" in the general direction of the transmission antenna of the station(s) for which reception is desired. Stations with broadcast antennas to the side or the rear of this antenna won't be "seen" as the antenna is highly directional. Having said all that to get you up to speed on some fundamental concepts of the antenna, as we move up the frequency spectrum (starting "low"), the gain of the antenna will increase until we reach the "center" or the "tuned" frequency for that antenna. After that, increasing the frequency will result in signals with increasingly lower gain.
How big is a typical home in Egypt?
The size of homes in Egypt varies greatly depending on the area and the income of the owner, but in Cairo, a typical home is only about 100 square meters in size.
Why does my radio antenna only work when I touch it?
The radio antenna may only work when you touch it because your body is acting as a conductor, improving the antenna's reception by grounding it and reducing interference.
What happens when Turning up the transmit power or utilizing a high-gain antenna to reach wireless users from a distance increases your exposure to .?
Turning up the transmitter power is a good way to insure that more cellphones, farther away, can hear the base station. But it doesn't to anything to help the base station hear the cellphones that are farther away. The only way to increase the coverage range reciprocally is to do something with the antenna. But that's a catch-22 . . . a higher-gain antenna has a narrower beam-width. So it works farther out, but only through a narrower 'window' of directions.

How many directors and reflectors in Yagi Uda antenna?
yagi udda antenna has only one reflector...but it has many directors...depending upon gain and efficiency...the length of reflector is normally...more than one-half of wavelength... and directors have a length less than one-half of wavelength...
What are the parts of an yugi-uda antenna?
directors and receivers are the main part of a yagi uda anteena there can be many directors and receivers as more receivers will surely increase our gain but we use only one receiver because the gain will not increase much but the cost will surel increase
Why does my stereo only play AM and not FM my 2001 Kia Rio1?
The antenna wire being unplugged from the antenna can cause this.
Are digital converters necessary for every home?
The only time you will be in need of a digital converter is if you currently own an analog television that is connected to an over-the-air antenna signal.
What is the voltage gain of the 2n2222 amplifier?
A: The gain of a transistor is not linear and even that varies from component to component. The gain can vary greatly depending on the Ic current and the load. Manufactures only give out a typical gain for a particular current. As a rule the lower the Ic current the higher the gain. To really find out what a particular transistor characteristics are a tektronik curve tracer is used.
What is an antenna and what is the difference between an omni antenna and a panel antenna?
"What is an antenna": the antenna is a device that couples electromagnetic fields between free space and a circuit (radio, cell phone, etc.).An omni or omni-directional antennais one that works equally well in all directions. Real antennas can only approximate this to a greater or lesser degree. In most applications, but not all, when someone says "omni antenna" they mean it works the same as you go around the antenna in azimuth.The shape of a "typical" simple donut explains this very nicely. Going around the round edge of the donut, it is the same in all directions. But if you go up from the edge to the top of the donut, its shape changes. It's the same with a simple omni antenna. If you have one on your desk as a wireless access point and you walk around the antenna at the same distance, it will work just the same at every point in your walk. If you climbed up a ladder, though, then as you go up the ladder you will be going towards the top of the donut and how the antenna works will change.A panel antenna is made very differently from an omni-directional antenna. It works a bit like a flash light, focusing all the energy in one direction. If you had a flash light sticking out from the front of a panel antenna, you'd see it stick out a lot in the front and only a little to the sides and up/down. Likewise, the panel antenna works mostly straight in front and only a little to the sides and up/down.
