How long I will gain if I'm using 15dbi omni-antenna + 100W signal booster?

I have planned to deploy 15dbi omni-antenna with 100W signal booster, If I can gain more than 25 kilometers in 360 degrees maybe that's the best for me move-on. What are the possibility of disadvantages and advantages if I will going to used that certain specification?

Please help me I will give you 100% solved I sound interested.


Best regards,


Philip

Here is a chart that will help you. with more info you can get more exact, but to answer what I think is your question, it would be about 1-3 miles. Without knowing the Mbps I can't be more accurate.

as far as advantages, theres no more than any other except for distance. Disadvantage...don't see any.

If i have a smart tv, do I need a booster for an outdoor antenna, I am planning on a 20-30ft pole, for the antenna


The benefit and functionality of a smart tv is derived as much from a good internet connection as from decent signal strength from the antenna.

The ideal height, type and direction of the antenna depends entirely on the signal strength available where you are and the length and type of downlead cable.

If the signal strength is poor it is generally better to use a high gain wideband aerial designed for fringe reception than to use a lower gain and a booster.
It is worth noting a booster can usefully help increase the strength of a weak but good quality signal but there is little advantage boosting a signal that is both weak and poor quality so it is best to obtain the best signal possible before considering a booster.

A low specification downlead can reduce the signal and gather interference causing a bad signal/noise ratio. Using a booster at the end of such a downlead will boost the interference as well as the signal - the best place for a booster is as close to the aerial as possible and masthead types are produced to avoid those types of problem.

It is best practice to use the highest quality downlead cable - double wrapped air spaced low-loss 75 ohm coaxial cable.

Is there a antenna or a booster that i can use in the house


There are many antenna systems available for Off-the-Air broadcast TV. It depends on space available mainly. There are internal (inside the home) and external mounted systems. Some external antenna can be mounted in the attic as well. External antenna are usually larger and cable of receiving signals from longer distances. They are either directional (point in one general direction at a time) ir omni directional (can receive signals from 360 degrees without physically aiming or pointing the antenna). They also can come with amplifiers/signal boosters, motors (to rotate the antenna for better recepton without manuall shifting it yourself). You can add splitters ti provide signals to more than one TV at a time. The number if channels you receive can depend on many variables so, depending on your location, how far away from the broadcasting antennae you are, and how you mount your antenna, the number of channels & quality of receive signals will vary.

Good news is there are websites on the Internet that can help immensely, so you don't to hire an electrical engineer!

Is that a little 2.4GHz antenna on the reciever? Have you tried using another antenna? (If its replaceable)
On the other hand, try converting signal from omni-directional to directional.
One can increase the range of the transmitter/receiver pair by using a high gain directional antenna. Home-brew instruction for making a high gain antenna can be found at:

What would I get longer range from a 49in 3db antenna or a 35in 6db marine antenna?


The db of gain is the important factor, not physical size

WIRELESS OUT OF RANGE


Move closer. That's not always an option though. Here are some tips to improve the range of wireless routers:

1) Locate the router higher in the building rather than lower (1st or second floor is better than a basement location).

2) Place the router in a location that will offer the least resistance to the signals - it is easier to pass wifi signals through gypsum board than it is for concrete / brick or walls with aluminum siding on them.

3) Change the antenna(s) on the router to a type that offers more gain. Typical router omni directional antennas offer 3dB to 5dB or gain - there are others that offer 7 dB or more of omnidirectional gain for reasonable prices. The antenna gain works for both transmit from and receive to the router.

4) if the device you wirsh to connect to the router is in one place, consider a directional Yagi antenna. These antennas concentrate the entire wifi signal in a direction that is 30 degrees wide and can allow the signal to be seen 5, 6 or even more times further in one direction - instead of being spread out over 360 degrees. These antennas cost a little more, but can solve the problem quickly.

5) Replace the manufacturer's stock firmware of selected routers with a 3rd party type such as DD-WRT or Tomato. Either of these will work with your Linksys WRT54G router. One of the benefits is the ability to boost output power of the wifi radio in the new settings the firmware offers. Read about both and decide if either is something you're comfortable doing.

6) Add additional wifi routers configured as a bridge or an access point to extend the wifi signal into an underserved area. DD-WRT supports bridging as shown here.

I hope this helps & good luck!

How do I strengthen my wireless signal? I am using a Linksys router.


The easiest is to replace the small antenna with a higher gain one. You get some very effective 8+ db gain omni directional antennas for linksys on ebay, amazon etc.
If you are in one direction you can also use a Yagi antenna (Directional) with high gain (20+db gain)
Normally the problem is not just the router, but the connecting device as well.
Keeping in mind you have 2 way comms between 2 devices. The router and say a laptop. ideally you should upgrade both antennas. As the best antenna on an Linksys AP will not fix a weak laptop signal. (it will transmit better, and receive better, but the laptop should also transmit and receive better)
Hope it helps

I'm trying to set the digital channels on my durabrand tv and i get the message that digital channel signal strength is low. what do i need to do?


If you are using a regular antenna to receive the signal, then you would need to either find a signal booster of some sort, or improve the antenna. There are many antennas out there for the digital era, most of them are set-top multi-/omni-directional ones, but they have their limitations. Unfortunately to get a better signal, typically an outdoor antenna is needed, or a large expansive one in the attic.

Compatibility with Sitecom wl 031


This 10dBi omni directional antenna enables you to very easily extend the range of your wireless network. By linking the Omni Antenna to your wireless router, you gain the benefits of an optimum wireless signal while minimising the number of ‘dead spots’ (points in your home where the signal is either weak or lost).
However it does not fit the following types of routers,modems and accespoints:
WL-143
WL-122v2
WL-114/WL-517
WL-114v2
WL-108/WL109
WL-111
WL-106
WL-025
WL-018v2
These antenne's will also fit other brands of wireless products that use an SMA connector
