Unfortunately, CB radios are limited to the 4-watt output power of the FCC (Federal Commission Commission). This is the most radio frequency output. This limitation is imposed because the CB radios operate at a frequency of 27 MHz, which FCC uses as a free 11-meter Citizens Band. Limited frequencies (or "channels") due to public access; congestion and interference are always a cause for concern.
Many new ones because of their hobby or operation imply that they illegally modify the CB radio (known as "Peak and Tune") or worse, amplifying is the only way to improve CB radio performance and range.
This is not really true, and in all honesty, antenna types and settings play a much bigger and more influential role in CB radio ranges or most of these types of wireless communication types. This is because, from the point of view of operational efficiency, the antenna antenna, the antenna type and the gain there, as well as the height of the antenna play a greater role in the performance of the radio, are much more critical to the radio than any other aspect of the hobby. Fortunately, the FCC provides much more freedom and what can be done and / or improved with regard to CB antennas! As is apparent from the preamble to the first few paragraphs, the recommendations for improving the CB radio's legality will be related to antenna setup:
1. Antenna Mounting Height – Nothing is more important than leaving the antenna to fix the maximum signal, rather than placing the antenna in the highest possible position. If the base station is set, the antenna is placed at the top of the roof, or a good sized tower above the nearby terrain, and buildings are key here. When in motion, place the antenna at the top of the car where the antenna can be earthed and securely grounded.
2nd Antenna size – Generally, the larger the antenna size, the greater the efficiency. Generally, larger antennas are needed for 27 MHz to prove the highest efficiency. What happens if the antenna is sized by size, coils, inductive elements, capacitors or even worse, yet resistors must be provided to electrically fit and adjust the antenna. Thus, not only the size of the effective capture area will be lost because it does not have a "higher" antenna, but it causes a loss to the antenna when adding extra components to electrically adjust the antenna. Mobile antennas, generally 8 "6" and 22 "6", are ideal for maximum performance
3. Antenna Type – Like any other, not all antennas are equated to the actual gain. Higher-gain antennas exist and, because of their design, focus not only on the desired direction, but also to pick up less noise from unwanted sources / directions. Some of the higher gain antennas are between the Yagi and Quad antennas, and can contain up to 2 to 16 antenna systems from anywhere. These antennas can effectively amplify CB's radio signal 10 times or more!
4th Earth, soil and more land! – The electrically grounding of the mobile antenna is critical because the antennas are dependent on the return path and need a large ground plane or a "counterpoint" to perform it efficiently and efficiently. This is critical to most base aesthetics, only because of smaller size constraints, and can be done with a "raised ground plane package" or standard "ground radials". Tune the antenna! – If that's not enough, you have to tune and check the correct turn on your antenna. This includes the use of an accurate SWR meter or even more an Antenna Analyzer to make sure that the antenna is tuned to standard 50 ohm tuning. This is reflected in the SWR – Station Radio Metering. The ideal reading is 1: 1, which corresponds to each watt power transmitted by a CB radio, 100% of which radiates forward, without detectable amounts of reflection due to incorrect antenna launch. Perfect reading is not always possible; although reading more than 2: 1 can literally damage the radio, always check, adjust and check your antenna.
