If you already have 2-3 bars, you’ll probably end up with full bars. – Guide by Expert. SHARES. Folded dipole. If you send 100 watts up the line to one yagi you have 100 watts largely focused in the direction the yagi is pointed, dependent on number of elements and boom length. The antennas have female N connectors. When the pass starts, aim the yagi toward the satellite, then sweep it right and left slightly until you hear something. Thus they have to be perfectly aimed towards the cell tower of your location to ensure strong cellular reception. The Yagi-Uda antenna--often just called a "Yagi"--is a popular antenna due to its gain, directionality, and relatively lightweight design (see the figure to the right). How to aim a Yagi antenna – Easy steps to connect your Yagi antenna. If, while testing, you find that there are warning lights on the booster, consult your owner’s manual for information on what caused the warning. You can see the horizontal and vertical elements share a ground element. Always aim for a near-full signal indicator; that means 90% signal strength or greater. How to aim a Yagi antenna Mount it such that it is horizontal but all its elements are vertical. I have installed a Force 12 6 element HF yagi, and the others I recently rebuilt are ready to go back up. That's why we always aim to keep lower-band antennas completely outside of the capture area of any higher-band antenna. In other words, they should be straight. Mount the Yagi antenna horizontally with its elements in a vertical position pointing straight up and down. The phone(s) should be in Field Test Modeso you can take decibel signal readings, which are more accurate than bars. Once you know what direction the antenna should be pointed, try to find a location on the building so that the antenna is pointed away from the building.

After all, I had another HF yagi to put on the tower and bigger fish to fry first, but planned to come back to this and rebuild it later. Released initially exclusively for MIA Members and now available to the public. $249.99. 0 823 . If you fail to do so, the reception won’t be any better. They keep the signal narrow on both planes which helps battle interference. This can correspond to the 8 compass points (N, NE, E, SE, S, SW, W, NW). By Diana Eng “One of my favorite things to do is talk with other ham radio operators through satellites or the International Space Station (ISS). Once you have the signal readings, you’ll want to find the direction that gave you the strongest readings for al of the carriers that you want to support. To aim the antenna, you’ll ideally need two people. UberSignal offers complimentary system design services to create the perfect solution for your situation. For example, a -70 dB reading is better than a -90 dB reading. It is known as the ‘antenna dance’. Can You Use a Satellite Dish as an Antenna? I think this results in slightly lower gain than using a full crossed yagi. Figure 10 shows the JoGunn driven element as if we are looking straight down the boom at it.
