For sure the television reception in the range of decimeter waves, recommend using double spiral antenna, the production of which under force even to the beginner. With linear polarization, a sufficiently narrow radiation pattern (width of the lobe in the horizontal plane is less than 35°) and the gain is nearly equal to 22 dB, this device is more compact than the widely known multiple-element designs such as “wave channel”, a bandwidth significantly exceeds them!
A conventional spiral antenna with number of coils is more than three characteristic of circular polarization. It occurs where the diameter of each of the coils of the active element is approximately equal (taking into account the velocity factor) of 0.31 ƛ where ƛ is the wavelength, which must be calculated in this unit. However, if you are not one, but two active elements having opposite each other the wrapped (when one coil is twisted from left to right and another from right to left), it becomes possible to effectively radiate or receive linearly polarized waves.
For obtaining unilateral directivity and increase the gain of this antenna is the reflector. It is set generally 0.1 Зƛ, to the place of soldering (beginning) of the spirals.
