What is use of LPDA antenna?
One large application for LPDAs is in rooftop terrestrial television antennas, since they must have large bandwidth to cover the wide television bands of roughly 54–88 and 174–216 MHz in the UHF band. The following article will give a brief overview of how many types of these antenna can be used at each frequency band, which is also known as the radio frequency band. You will find most of them listed below these two sections. The first section defines all forms of an antenna, while the second section will provide examples of different commercial applications.
Types of An Lpda antenna
A Long Range (LR) antenna has a wider coverage than a short range-only (SR) antenna, so it is suitable for applications such as satellite dishes or high-speed communications in low Earth orbit (HEOS). In terms of coverage, LR antennas are less sensitive than SR or SIRR antennas and only require less power than SRs. For example, some SR receivers use the same frequencies as an LR station, so that they need an LR antenna. They are generally made with an array of multiple antennas. Also, an LR antenna, unlike a SR antenna, need not be powered by batteries because other components including the RF amplifier and receiver can take care of the battery and operate independently. In addition, the number of antennas required depends on the desired spectrum band. As such, when constructing your own LR (LR) antenna, you may always consider using arrays with more elements than the desired one.
