My collection of 23cm SOTA antennas includes two DL6WU homebrew folded dipole yagis, 6 and 12 elements. 4) Directional antenna can be used in combination with omni-directional antenna. 6 λ in total length and. Although the Yagi has become particularly popular for television reception, it is also used in many other applications, both domestic and commercial or professional. 11 E-plane radiation pattern for CO and CROSS polarization on the quasi Yagi antenna. fabricated nonreciprocal Yagi-Uda filtering antenna and the reference antenna are given in the insets of Fig. It is ideally suited for directional and multipoint IEEE 802. minimum height of the mast for installation on the roof of [Min. Here's a simple Saturday project: build a portable VHF yagi antenna for 2 meters. 6 dBi, 700 - 2500 MHz Frequency, Vertical Polarization, Uni-Directional, Outside, Fixed-Installation Antenna, Weather Resistant, Mounting Hardware Included. In this instance current in the unfed yagi is ~10% that of the fed yagi, which is pretty good so far as stacks go. If you have weak stations, consider a high gain antenna, whether it be a yagi type or a 4 or 8-bay antenna. 4 GHz regime, anyway) to be exceeded through the mechanism of reducing transmit power and then. The frequency is the number of oscilla- tions (or cycles) per unit of time. The antenna was shown to demonstrate a peak gain of 12.
