If the signal strength still too weak, you can trial and error increase the outdoor unit the center core round / turns 1 at a time. If you not very sure, just make it 7 round /turns at out door unit and 5 round /turns at indoor unit. ![]() Probably take a while for getting the right place. Use your smartphone searching for the location have STRONG 4G signal to put the outdoor unit.Ī good signal strength define is maybe a stable 3 bar 2G signal, not a unstable signal strength jump up and down too often. Do not forget the red wire.Īfter some testing, B1-WCDMA 2100, 4G have to be center core 7 round /turns at outdoor unit, and center core 5 round / turns at indoor unit. Remember the edge of the center core wire have to joined the iron wire and tighten. Now we need to mount this wireless antenna to the 3G antenna. Then straight the center core both area like the photo. About 5cm from the edge of the center core, we need to make 5 round / turns clockwise, E GSM 900 2G, we can do it using screw driver, just bend the center core round and round / turns on the rod. Then back to the cable, cut off the dielectric insulator carefully, we need the center core for building the wireless antenna.īack to the drawing again. Just twisted down the metallic shield become a wire without cutting and fit into the connector block at the red line and tighten, not necessary a U shape. Now you can see the like a spider web, cut off this metallic shield and look at the drawing again, the red line is the metallic shield to be installed. depend on the center core round / turns diameter. So first cut off the plastic jacket about 15-20 cm length, depend on the center core round / turns, if you planning for testing the center core round / turns, maybe good idea about 20cm. This section we need to use the common cable TV cable. Next step is the wireless antenna, the orange and yellow drawing. One clothes stand enough for building 2 unit this kind of antenna. You have to use the wire cutter to cut the wire. The 4cm area, clean/remove the clothes stand / wire coat hanger shield.
