How to make FM antenna

the creation of the FM antenna from what was at hand. Here are two ways, the first way is easier, but unreliable, the second more verlaten that you can get something

Instruction

Difficulty level: Difficult

step 1

The first way Sdelat frame small perimeter of any shape and turn it 75 Ohm cable,

2 step

Second sposobstovat frame with a shrug.

3 step

Shoulder length is calculated by the formula L=300/F/GE F is the frequency band to which the antenna will be caught (for example, take the middle frequency range, i. e. the F=98 MHz; calculate L=300/F/4=0,76 m, then, it turns out length one shoulder 76cm)
