How To Tune Cb Radio
How to tune CB Radio Antennas to your Frequency
You should tune CB radio antennas if you are having problems with output power on radios. This is arguably one of the most important steps when it comes to properly installing CB radios and their antennas. If you properly tune CB radio antennae, your radio will have a stronger performance. Failure to tune CB radio antennae can lead to a poorer performance, as well as cause damage to your unit. However, before fiddling around with your antenna, you need to make certain you understand the fundamentals behind tuning and the Standing Wave Ratio (SWR).
What is tuning? This is the process of adjusting or "fiddling with "an antenna in order for the radio's output power to be converted into efficient radio signals. This is actually how you tune CB radio antennas. What you are basically doing is increasing or decreasing the antenna's length in small increments until you reach your desire frequency or signal range. The primary purpose behind wanting to tune CB radio antennas is to equal the physical strength of the antenna with the strength being used through frequencies. This is one way of ensuring maximum performance potential as well as transmission efficiency.
The efficiency of an antenna is measured by the SWR, which signifies the amount of power being converted into radio antenna signals; therefore, if you have a reading of 1.0, you are also transmitting 100% of the radio's power. On the other hand, a reading of 3.0 signifies that only a 3rd of the radio's power is being transmitted through the antenna.
In order for one to tune CB radio antennas properly they must get the lowest SWR reading possible. A low SWR reading will ultimately result into better performance while a high SWR reading will result into the opposite or even damage the radio. How does this happen? When you get excessive output power it transmits heat and the heats is directed back to the radio, which in turn causes permanent damage to your unit.
First and foremost, if you plan to tune CB radio antennas as a profession, you must also know how to properly install CB radios. Plus you will need a SWR meter as well as coaxial jumper cables. These are just a few intangible necessities to get started; nevertheless, if you can find any open area, hook up your SWR meter and read them properly then you are well on your way to starting a lucrative business on how to properly tune CB radio antennas.
