A radio works by receiving electromagnetic waves which wander in the air around us. It does this by the help of an antenna which is a device that helps capture the waves and which is made of stainless steel. Antennas are known to change lengths and heights and are of many types and varieties depending on a number of applications and uses. Read this article to now how AM/FM radio antennas work.
Types of antennas
There are many antennas with specific purposes. For instance, the TV antennas are used to capture relevant TV signal frequencies. AM antenna and FM antennas aid in capturing radio frequencies and this is characterised while using radio tuners to search for frequencies. At least, these were the characteristics of an analogue radio system back in the days. There are equally antennas for television sets as well as those used in cars. You will find portable antennas as well based on what you need to use this device.
AM radio is characterised by long antennas and lower frequency for efficient transmission. There are many stations with some being strong, while others are weak. While using the radio transmitter to tune, you will notice the signal either disappear or grow stronger based on the signal strength that the given frequency operates in. The radio antenna and tuner should be linked as there is automatic system in few types of antennas. Should the signal strength still be weak, you may use an amplifier antenna to strengthen your signal strength.
Type of radio in relation to antennas
Current rapid technological change has seen the radio develop into being more digital than analogue. The digital AM radio works differently from the analogue type of radio. As a matter of fact, radio HD is far much better and works well compared to the CC radio. The C crane radio for a long time provided the most reliable service in terms of frequency and radio signal strengths but this is fast changing with the radical changes that the industry is experiencing. Most digital devices come with amplifier antennas pre-installed and for this reason, the traditional steel antennas are no longer being used. Preservation of analogue devices As much as the world is embracing the digital age, we cannot deny the fact that a number of people are still using analogue devices and systems. This will aid in helping even the younger generation to understand the use of antennas in our old analogue radio devices.
