The trombone antenna

If you have any research on antennas, you will notice that there are several types of antennas around. Two types are omnidirectional and directional. The difference between these two types of antenna is a simple but important. A directional antenna transmits its information in one direction, while the omni antenna transmits the information in all horizontal directions.
In addition, you need to understand how the antenna efficiency, or gain, works as related to other antennas. Antenna gain is measured in decibels isotropic (dBi), defined as the strength of an antenna compared to a theoretical point of view around an imaginary sphere antenna. dBi is a logarithmic measure, so every 3 dBi is doubling gain.What you need to know is the higher the dBi, the more sensitive and more focused antenna.
Construction of the antenna trombone
Construction of the antenna is a process in seven steps as follows:
1. Prepare elements of the antenna
2. Get the mounting platform ready
3. Create a driving force or dipole
4. Prepare the mat
5. Set the mat on your new antenna
6. Set the mat
7. Insert the remaining elements of the antenna
