2023年8月18日 · Simple Construction of Wire Antennas. last updated 18 August 2023. Building a Simple HF Dipole Antenna. A wire dipole is one of the easiest antennas to build, and the same methods can be used for most other wire antennas. By choosing the right materials, and not worrying about how other books show to do it, it can be quite easy and quick.
Ideally, a loop antenna is designed to be portable, easy to assemble, small enough to use when camping or operating in remote locations, and able to cover several bands. The drawback of most commercially available loop antennae is the price. They range anywhere from $300 to $500 according to advertising on the Internet and in catalogs.
antenna construction to simplify the otherwise difficult to comprehend technical jargon. The antenna designs presented here are specifically cut to the dimensions necessary f or proper operation in 140 -150 MHz VHF band. Each chapter deals with a particular design and an extra chapter at the last part is added to help the
2021年7月28日 · Antennas are much more than simple devices connected to every radio. They’re the transducers that convert the voltage from a transmitter into a radio signal. And they pick radio signals out of...
In this article I will cover several topics given that the subject is about building an Antenna System and not just the antenna. There are four specific areas we will dive into, the first is the antenna, the second baluns, the third chokes, and lastly the transmission line.
Antenna Tuner Should be located at the Antenna if possible; Everything beyond the Tuner is the Antenna Doesn’t like tuning into Coax; Outside of Coax becomes part of the Antenna
