I built the whole system by myself,with the material that you can find in the island, witch is not much!

 

there is no road to my house , and i have to climb about 50 meters of stairs to bring anything.So the 4.7 meters antenna had to be transported by hand, with the help of some friends.The antenna divides in two parts,each one is more than 200kgs.

Unfortunatly, i have no picture of the transport,from the top of the island to the front of the house,but it was ....special.....
