EH 160 mt
The First Prototype (1)
As I said, follows a short technical description of the first EH antenna I've built (as I'll explain later, I've built a second one).
we make the cylinder, using 10/10 aluminium foil with following measure: 82x37,5 cm;
turn it around a 250 mm PVC pipe, make same 3 mm holes every 5 cm and then lock with a rivet;
Now the first cylinder is ready;
Insert the first cylinder in the 250mm PVC pipe (10 cm) and lock with rivet; now make the second cylinder and cut the 250 mm PVC pipe at 45 cm: you will have a 37,5 cm cylinder + 25 cm space (PVC) and a second 37,5 cylinder
Lock the second cylinder with rivet;
Make 1 turn of wire on each cylinder as in picture;
Cut the wire longer (you will connect there the network,later); the upper "coil" wire will pass in the center while the botton one on the side, near the cylinder.
