A close up of the antenna, notice the support for it, built from a 2x4cm steel rectangular pipe. The original DIRECTV feed was used as a reference for positioning.

The antenna from another angle. The antenna cover was made from a small piece of thin wood, everything was painted gray.

Wireless can antenna used as a feeder to a DIRECTV 1.1 meter dish. Notice the dish is used upside down, we want it pointing to our base antena, located in a 40 m tower, one km away. If we used the dish in the upright position, we would have to point it in a negative angle, almost looking down, because this is an offset dish.
 
A side view of the dish and the feeder. The dish inclination is about 60 degrees according to the scale engraved in the DIRECTV base. The dish appears to be pointing to the sky, but remember, this is an offset dish, and we are using it upside down!
 
I only used the wireles lan card configuration utility to point the antenna. The can antenna by itself reported 43% link quality and 43% signal strength. With the dish, I got 100% link quality and 80% signal strength.
