Join directional antennas easier to build single biquad is one of the greatest scope gets. We actually managed to establish connections from one access point through a single biquad antenna to wireless network cards in PCs located at a distance of 2,5 km unhindered. In the next article we will show step by step how to build a single biquad using materials readily available in Cuba.
- A metal plate known in Cuba as (auto sheet metal work) 15×15 cm
- Copper wire power cord 2mm thick.
- Copper Pipe 5cm liquefied.
- Soldering iron and tin.
- Punch or drill same thickness as the aforementioned gas pipe.
- Cegueta metal cutting.
We begin with the copper wire 2mm wide take a stretch of about 32 cm and make folds 3,5 cm long to form a rhombus as shown below.
With this method we have to use any type of connector as I explained above are expensive and difficult to obtain.
Well now we take the sheet metal plate or car and draw two lines cross to get a point in the center where a punch or drill will open a hole to the same. And we proceed to introduce soft soldering and the gas to metal plate separation 1,5 cm.
Once attached, the sheet metal welded to the pipe 5 cm proceed to solder our current station copper wire to the tip of the gas pipe in the manner shown below
This will allow the tube to introduce gas above the coaxial cable prepared in this manner.
We soldered the positive and negative station coax entering the tube set contacts for Antenna Grounding and being ready to use the single biquad.
Practice has shown that this antenna is very useful and easy to build. It has the advantage that it is small and easy to hide among television antennas that exist in Cuba or elsewhere of a roof that is difficult to identify, above eg water tanks confused with the electrical system themselves off automatically. We always advise to a good height and use the shortest possible cable size avoiding signal loss.
