How to Build a Tin Antenna CDMA 1900Mhz

Who knew that with a can we can make an antenna for CDMA Mobile 1900 MHz frequency. After searching for information about the calculation of the antenna I found the calculation for Frequency 2.4Ghz Antenna Cans. Armed with this data I am trying to calculate antenna Mods cans 2.4 GHz frequency so he could work on this 1900Mhz.Berikut the necessary equipment:

. Cutting pliers

. Drill

. Cutter knife

. Tang shark

. Tin solder

. RG58 cable (cable TV antenna can also be) long, according to the respective regional

. Milk cans “Pediasure” completed 800gr (not milk promotion…) looking for the former only if buying all their milk 150Ribuan expensive (not cheap it would make the antenna cans … ….)

. Male female BNC jack (can also jack type)

. TV antenna jack Male Female

. PCB size 4X8 Cm (Make induction antenna on Mobile)

. 0.8mm copper wire (copper wire can be large)

After the above equipment have been ready all of the following steps of manufacture:

1. Clean the paint on the outside of the cans

2. cut along the 30 716-mm copper wire and copper wire are soldered to the end of the BNC jack female

3. Punch a hole the size of cans of female BNC jack. Hole distance of 38 401 mm rear cans. And plug the female BNC Jack-me-soldered with copper wires into the hole cans. So that would be like this

4. Create a smooth induction of the PCB antenna with a way to make the flow path as pic below with a cutter knife. Thus forming a groove / line up and down. TV antenna jack soldered to the PCB female, middle path to ground while the edge of the PCB to the antenna who is connected to the copper wire on the antenna cans. Note the center and edge lines are not related.

5. Edge Connect the antenna cable to the male BNC jack

6. Connect the other end into the antenna cable jack male TV antenna

7.Pasang Jack to Jack BNC male BNC female while the male jack to jack female antenna TV antenna TV antenna on Pc induction antenna. Now ready to be installed outside using bamboo stick. Dan point the antenna to the nearest provider BTS

8. Manufacture and installation of the antenna is completed. After it was over PCB Induction Place Mobile antenna and see the change of signals obtained small signal means the direction the antenna is not true, look up the antenna direction to get who is better

Note: If in your area have gotten without the antenna signal but only a few bars in the pairs of antennas do not need to put an antenna outside enough on the computer and locate the antenna jim-dandy way to get additional bar “Haier dp1200” signal and ready for use for a modem with a stable signal who

Antenna specifications:

. Working on the line frequency: 1464.402 MHz (low frequency) s / d 1912.917 MHz (frequency upper)

. D = 120 mm (diameter cans)

. Lg / 4 = 38 401 mm (distance behind the copper wire with tin)

. Lo / 4 = 30 716 mm (height of copper wire)

. 3/4Lg = 153 603 mm (length tin)
