Why is Yagi antenna directional?
Yagis are directional antennas. Most of these antennas have a 50° to 70° beam width. Because they focus all their input in one direction, they put out high gain relative to omnidirectional antennas. This makes them ideal for receiving lower strength signals.
How far can Lpda antenna reach?
Paddle antennas (LPDA) typically offer about 5dB and Helical antennas about 9dB. There are even specialty Yagi antennas that can offer even more. Team that up with better quality, low loss coax such as RG8x/LMR-195 for runs up to 100 feet or LMR-400 for even further and you may well have solved the problem.
What is vertical azimuth?
Vertical or elevation PATTERN is the shape/size of the beam up and down. Horizontal or azimuth PATTERN is the shape/size of the beam side to side.
What is a good LTE speed?
A more standard high speed rate for LTE (or 4G LTE as is the common standard now) is 20-25 Mbps download. Upload speeds tend to be on the lower side of 10-15 Mbps. Each carrier is different and has a wide variety of options available–always check with your provider first.
How to aim a Yagi directional outside antenna?
Ideally, you want the antenna mounted to a pole that you can hold rather than holding the antenna directly since holding the antenna can affect the performance. Start with the outside antenna aimed in one direction. The person inside should then wait 60 seconds and then record the signal readings from the phone (s).
When to use a non conductive boom for Yagi?
The bottom line is when using a non conductive boom or simply isolating the element’s from a conductive boom the Yagi becomes much much quieter as far as the signal to noise floor goes. A matter of hearing the someone or not?? My conclusion from building many different Yagi’s for vhf/uhf/hf…. is I agree..
Where does the zero current go in a Yagi?
So, by design, the elements of any Yagi have a zero current going through the center point. That’s pretty obvious be symmetry: assuming you excite the “left and right” halves of the driving dipole with exactly opposing voltages, everything should be symmetrical across the plane through the middle of that dipole.
What are the 8 compass points on a Yagi?
Next, rotate the outside antenna 45 degrees or 1/8th of the way around. This can correspond to the 8 compass points (N, NE, E, SE, S, SW, W, NW). Once the antenna has been rotated 45 degrees, the person inside should again wait 60 seconds and then take another set of signal readings.
