A router and the previously purchased 2.4 directional antenna, since the hands of such things, I do install and router cooling these parts of the tutorial, technical content is not high, but the effect is still more obvious! ! ! !
Directional antenna: A directional antenna, which shows radiation in a certain range of angles on a horizontal pattern, which is usually referred to as directionality. As with omnidirectional antennas, the smaller the lobe width, the greater the gain. Directional antennas are generally used in communications systems for environments where communication distance is long, coverage is small, target density is large, and frequency utilization is high. We can also think of the relationship between omnidirectional antennas and directional antennas in this way: Omnidirectional antennas transmit signals in all directions, and signals can be received from both the front and the back. The directional antenna is like a bowl-shaped reflective surface behind the antenna. The signal can only be transmitted to the front, and the signal to the back is blocked by the reflecting surface and reflected to the front, which strengthens the signal strength in front.
Directional antenna dismantling:
The directional antenna is actually the simplest kind of product. After you open it, you will find nothing in it.
Hit these six screws,
All will think that the antenna is a very precise thing, just a PVC board, and the production process is also the simplest! ! !
Installation process:
Now you need tools and remodeling stuff! ! Soldering Iron, Heat Shrink Gun, Screwdriver, Antenna Interface, Antenna, Feeder, and Some Small Things!
The dismantling of the router is also very simple. It is only necessary to disassemble the following two feet of the router. There are two screws inside. Remove the screws! Gently lift it!
Inside the router is also very simple, I this is 840n, there are two antennas we modified only need to change one.
What we are doing now is to remove this antenna from the head with Luotie!
Next, you need to get the antenna
This is the main core inside the removed antenna! ! ! There is nothing to see but it depends on it!
This is where we need to install it on the router and replace the antenna just removed!
Welding is completed. Fix it with a heat shrink gun to prevent it from being knocked out!
Put the antenna head sma head fixed to the original place! Antenna sma head to complete the task! ! !
Install the router, connect the antenna, and simply test the antenna in front of the window! !
This is the place I want to test. It's almost 320 meters on both sides!
The 13% of the signal before the antenna was not installed could not be connected to the Internet at all, and the effect of installing the antenna was completely different. This is the difference!
This effect is beyond my expectation!
Only need a dime to rebuild the router cooling
Say a good dime, certainly will not let him more, I now use the silicone! I used to get up and down from the computer. This is not money. Apply it directly to the top. Put a dime on it. If you don't have rice noodles? Telling a suggestion to you just needs to put your toothpaste on it, but the toothpaste needs to be put in very little and the toothpaste is conductive! ! Silicone is also conductive, we can pay attention to it! ! !
This method can effectively reduce the heat dissipation of the router! If there is a friend who is afraid of falling down and can stick tape, it is generally not a problem.
