Can You Catch Genital Herpes From Blood?

Mounting a wifi access point on a terrace

The third, and final, article retrieved from trinidad.no-ip.com, mounting the access point of the terrace. To see other items from the old website Trinity, Trinity seeks

Finally, after a long time, I could mount the AP on the roof. It was not easy. The greatest difficulty has been climbing about 25 meters of cable from the fourth floor to the top of the lift. At first I thought up 220 volts, two cables, but in the end I used to simplify a system of POE (Power over Ethernet). For the POE, and to avoid losses because of the distance, I put 12 volts to the cable, and then sealed in the box above the rectified at 5 you need 3 transistors using the AP voltage regulators (7805). In theory each transistor withstands 1 amp load, as the AP needs 2, and to avoid overloading, Use 3.
Inside the waterproof case is the AP without housing to save space, and 3 transistors with their respective sinks. All holes have been sealed box using glue termofusor. Ethernet cable entry I make it through an RJ45 socket, also he is very comfortable to classify after wires.

even empty box with mounting screws of AP, and all facts necessary hole. Also this because the female RJ45 connector.



Attach the pigtail to the AP. As the PA has no external connector, and either find a connector for "it", I opted to remove the connector and solder the cable directly. Works:)

Riding transistors.

completely finished box, still in evidence at home.

First test with the antenna. As the AP has two antennas, which had to ensure was which.

Once done all played outside mount. The antenna holder to purchase is to screw in the wall (there is also the surface), because in my case as best he could assemble. With the 8 screws that leads, I doubt it with the wind ...
The cable is completely covered with aluminum tape (aka duct tape) to protect from the elements, especially moisture.

Completely finished assembly.



Almost a year later added a directional antenna to make a link with a neighboring node. antennas have been used DBi Stella Doradus, 19 on each side of the link. The distance covered is approximately 400 meters.
