A reflector a dipole one or more director elements The reflector is placed at the rear of the dipole. By RD Bentley on March 30 2015 in Geek Tipster Technology.
Making your own Yagi-Uda can be done very cheaply and requires only a few common tools. All other channels are in the UHF range. The mast has a height of 8m and can be erected easily without any helpers.
The Yagi antennas overall basic design consists of a resonant fed dipole the fed dipole is the driven element and in the picture above and the second from the left side with one or more parasitic elements. My shack for portable operation. This article demonstrates how to build a 14-element Yagi antenna for Verizon 4G LTE or for 3G in 10 steps for 10.
I use the 2×6-El-50Ohm-Yagi for 2m with 250m boom an 2×10-El-28Ohm-Yagi for 70cm with 2m boom. Connect the USB device to the antenna. Use Popsicle sticks to build the antennas backbone and hold it together.
YAGI Wifi ANTENNA CONSTRUCTION. BUILD YOUR YAGI ANTENNA. Here i present all steps to build this antenna.
The length is usually 5 more compared to the driven element. These adjustments can be easily and quickly made using antenna design software. VHFUHF Yagi Antenna Design Input.
Using the nut that came with the BNC connector affix. The dimension of the antenna below is. You will need to be able to mount it in a more-or-less permanent location as high as possible and aim it at the transmitter you want to receive.
The result of a number of days of tweaking lengths and offsets can be found in the following nec file gsm-900_6element_yaginec. Please Click here to get our yagi antenna.
