Very good condition. This is a Cushcraft 5 element 6 meter yagi, another fatality of my tower crash back in April 2016. With the 4 elements yagi we come on a point when we must pay serious effort to our mast and rotating system. with a boom of just 3. Only 1 left in stock - order soon. 1 dBi gain / 30dB front-to-rear; $ 99. 27 eBay determines this price through a machine learned model of the product's sale prices within the last 90 days. Computer-aided modeling and test range techniques were used by Cushcraft engineers to further optimize the performance of our popular 6 meter Yagis. The design of the Yagi antenna much depends on the operation quality of the antenna. Python program for running Particle Swarm Optimization (PSO) of Yagi-Uda antennas simulated with NEC2. When placing a parasitic element very close to a driven element, approximately. Buddipole - 6m Yagi Kit; When joining HamRadioForum you will get a confirmation email which you need to respond to. I got good use out of that antenna, but I decided to build a smaller 6-meter Yagi, dropping one element, and using a shorter non-hinged boom. M2 Antennas 6M7JHV 6 Meter Yagi Antennas is a mid-sized 7 element antenna designed originally for the late Dave Batcho, N5JHV. 4dBd YAGI $242. Shown are comparisons between model simulations and prototype measurements. Can use TV rotator and mast. A 6 meter vertical antenna must have at least 18 feet of active antenna to have 3 dB gain over a 1/2-wave dipole, and even then it might not be at the horizon, or may have coil losses, etc. The first design is actually to short to be called a real 6 elements monobander. We just made a good thing better maintaining low wind load and great performance. Version 2: With 8- and 10-mm-Elements (see down), built by SQ9VPA. + 7 S 0 P O N S O A R P A 7 E E D U J 0 F J Cushcraft A50-3S 3 Element 6 meter Yagi Antenna, 50 - 54 MHz. Antennas Antennas. That was until I made a QSO with K1MAZ (Nick) while he was doing a SOTA Activation. This page contains construction details on a 2 metre 144MHz VHF Yagi beam antenna, designed for portable use. Adding to your basket. 6 Element 6m 30m Monobander Smal 5 Element Yagi 40/20m: NEW. A 3 element Yagi Antenna for the 6m band from the Vortex 'Lightweight' range. One additional element parasitic coupled with a length of about a half-wave to a dipole will increase the gain from 0dBd to 4-5 dBd. 5 boom length of the cubical quad the results are just terrible for the Yagi, like 2 db down versus the quad!. Folded dipole has advantages over the dipole in greater bandwidth and higher impedance, and it can be more easily adjusted with a BalUn to 50Ω required by the most devices (this is not always correct. The result is lower loss and wider bandwidth.
