HyGain AV-640 Vertical Antenna 6m to 40m (September 2018)
Hy-Gains new AV-640 Patriot HF vertical is one of the best built and best performing (8 BAND 40/30/20/17/15/12/10/6) multiband vertical Antenna available today. Make full use of your sunspot cycle with the Patriots low angle signal. The AV-640 uses quarter wave stubs on 6, 10, 12, and 17 meters and efficient end loading coil and capacity hats on 15, 20, 30, 40 meters. Instead of typical lossy can traps, the AV-640 resonators are placed in parallel not in series. There are no radials on the ground needed!
Final installation and ready for operation with 1kW - no tuning anymore!
Many thanks to René HB9NBG and Carine HB9FZC for the proper installation of my new AV-640 vertical antenna :-) click on the picture to see the amazing video
