Here I will teach you how to make double antenna for GPRS/EDGE/3G/HSDPA
Board (used for the template attached) copper wire (taken from the electrical cable size 2.5mm) <- already long enough 1M
Pigtail <- adjust to the type of modem, for example Sierra 881U
RPSMA Bulkhead jack (Female) used to connect to Pigtail Cable (YAGI antenna could take from yesterday did not buy) n-male connector RG58 female / one pair
RG58 cable <- recommended search of the interior fibers of the color yellow (made of copper)
Empty PCB (for reflectors) can be made also from aluminum or brass
Equipment needed:
Pliers
Cuter
Isolation
Solder
Tenol
Coffee
ESTIMATED COST:
Blank PCB = $ 8
• N-Male Connectors RG58 = $ 1
N-Female Connector RG58 = $ 1
RG58 cable per meter = $ 1
NYM Power Cables 2.5mm size = $ 2
Pigtail = pretty expensive <- tutors make Pigtail Siera 881U can read here
RPSMA Bulkhead jack (Female) to make the connection Pigtail = $ 4
STEP:
Template used to create double biquad appropriate form of copper wire template
PCB cutting / plate aluminum / brass plate suitable size do not forget to make hole the middle (center) of appropriate size n-female connector RG58 copper wire pairs of the templates at no.4 RG58 n-female connector pairs of n-connector RG58 to RG58 cable one end (the shorter the better) I had a 12m long <- do not imitate this was possible only 10M RPSMA pairs Bulkhead jack (Female) at the end of RG58 cable for connect to another 1nya Pigtail completed, attach the antenna positioned high, while putar2 find the best way to get a signal GPRS/EDGE/3G/HSDPA
ADJUSTED FORM WITH ANTENNA taste
J1 = use the inner of the coaxial cable TV antenna (recommended take away from the antenna coaxial cable satellite TV, I do not have to use the commonly used coaxial UHF TV.
J2 = created from a blank PCB with a size of 5-6 mm width with a length to adjust the size of the reflector with a wire spacing (NYM).
This antenna has been shown to increase the signal 3G and GPRS
