How to make a antenna for the radio

Select a location for the outdoor antenna. If you live in a private home, the best option would be to install it on the ridge of the roof. To do this the two sides of the ridge hook strong rails with a height of about two feet and attach them on porcelain insulators. The aerial is stretched between the insulators, from her room to the radiowill go from the wire reduction.

Alternatively, one end of the antenna can be mounted on wood, always using the insulator, the second – on the roof or on the frame of the window. If you live in an apartment building and you have no possibility to put the antenna on the roof or give her to a tree, we should fix it in the house, the contour of the window frame. But the efficiency of this antenna is lower than the outer.

For the manufacture of antenna you need wire in varnish isolation in diameter 0.3-0.5 mm. From it using a drill you have to twist the antenna wire for this first 20-30 times route the cable to the desired length (e.g., 10 meters), clinging to the nails or wire hooks. Then remove the wires from one of the hooks, hold the drill tight and weave for stranded wire.

In the place where the antenna will be to move the wire reduction, a little rasplatita cord, scrape all the strands into a length of 2-3 cm attach them stripped wire reduction and carefully propagte. Strengthen the finished antenna on insulators and remove the wire reduce into the room. On one end solder a suitable plug.

Is the antenna cord can use a whisk of beam segments thick, with a diameter of 1-2 mm copper wire with a length of half a meter. The bundle of wires is inserted into a suitable metal Cup, e.g., aluminum from the condenser and filled with solder. The antenna is fixed on the highest possible place from her room there is a wire reduction.

If you have an external antenna be sure to set the lightning switch. During thunderstorms the antenna disconnects from the radioand closes with a switch on the ground wire.
