Yagi-Uda antenna (refer Fig. 7) is the most common terrestrial TV antenna used on the rooftops. It is usually used at frequencies between 30 MHz and 3 GHz, or a wavelength range of 10 metres to 10 cm. The design of the antenna depends on the number of elements used in the antenna.The design program is long enough without being choked with detailed explanations. The design program is best suited for antennas in the VHF, UHF, and Microwave frequencies because lower frequency antennas, that have gains between 11.8 to 21.6 dBd, tend to be physically impractical. For example, a yagi antenna for 50 MHz would have elements that are around 8 - 10 feet (2.5 - 3 M) long.

If you were unable to find a slightly longer length of rod for the reflector you can try using something like these M4 brass couplers to extend the length of the reflector (or all elements), this would additionally provide further tuning capability to the antenna. Aug 25, 2021 · The design of this LTE yagi antenna uses a microstrip antenna as its driven element with FR4 substrate type and a relative permittivity value of 4.6. The material used for the reflector and director elements is aluminum with an outer diameter of 8 mm and an inner diameter of 7 mm. Step 2. Cut the tape measure into four pieces. One piece will be 41 3/8 inch and the second will be 35 1/8 inch. These are the reflector and director elements for your yagi. The driven element is made up of two pieces, so cut two pieces that are 17 3/4 inches long.An efficient resonant antenna (1/4 wavelength or longer) produces a large- ... a yagi antenna with 6 dB gain is equal to a dipole with 400 W drive.
