Rear window antennas, function - GF82.62-P-3106-04GH

Model 163 

Function: 

The radio signals are received by the rear window antenna (A2/32) (AM, FM  ). The high-frequency oscillations (RF)  of the electrical field in the air are converted into an electrical alternating voltage  .

A standing electrical wave is formed in the antenna as a result of the correct matching of the length of the antenna to the wavelength of the frequency to be received.

In this case, the amplitude  of the RF signal  has a constant value at a random point of the antenna. The RF signal level  is at the maximum at the connection point. A variation of the length of the antenna from its optimum length results in a reduction in the RF signal level  at the antenna output. If the variation is too large, no further signal is received (for example if the antennas are incorrectly connected to the antenna amplifier).
