Improve Walkie Talkie signal by an antenna? - homemade antenna signal pre amp
Is there a way to signal with a walkie-talkie antenna to improve from home? I do not mean the invasion in a manner that does not only mean a better reception and maybe a little more distance
If yes, please describe how a create and not to join anything?
(I heard from one antenna to another matter, "a metal structure occur in conjunction with the size of a car?)

Homemade Antenna Signal Pre Amp Improve Walkie Talkie Signal By An Antenna?

There are several ways to access this - each with their own advantages and disadvantages.
Guess not want to spend much money, so an amplifier is connected to the power and signal mast with "amateurs" type antenna out?
Radio range can be improved with better land and a better antenna.
The only way to improve the land (earth), is a metal tip into the ground with a wire on the side of the antenna connector of the Earth) (usually the housing or chassis of the radio - but it can not be go. ..
Well, the antenna ... virtually all the walkie-talkies are delivered with a whip omnidirectional (or heel) of the antenna. This means that wherever the setting of a signal, so that the listener somewhere for you (unless you are very far, or there are things between you two), two RF absorber.
When the antenna "to the connection s / TW, then you can make an extension for the antenna can be higher in the air (mast) or outside a building problem - but then can not go ...
If you find the frequency of the / TW then (ifHeel air can be turned off), you can buy a Yagi (Directional Antenna), which usually looks) like a TV antenna (instead of the extension, and all power in one direction. To the point as a point with a fixed radius, it works well and can travel great distances with little power. But if you keep moving, you still have a problem that the antenna pointing in the right direction.
In summary, there is no simple solution. If you buy w / t, with a higher power, Tx, Rx and better sensitivity, you might help. There is a simple formula for the theoretical range for TX TX with more juice to be calculated. TX series is proportional to the square of the transmission power. Example - If you want to double the area, we need to quadruple the power - or 5 x x range = 25 power. Phones to solve this problem, obtain the tower with the strongest signal and switch to the tower, while you're away from the first. Army vehicles are signs of a whip antenna, air, altitude, power variable, and (made) a ground cable. Line of VHF and UHF are more or less the hearing. Ifwant more than that, you should short waves, which constitute a large air can go.
