I stumbled upon a new antenna system which appears to be streets ahead from competition, take a look at UltraBeam. Electronically controlled HF antennas. General coverage. Top features on all ham bands. Very advanced materials and state of the art technology. View the video above.
Photo below is for their UltraBeam - 4 element 10-20m 3 element 30-40m. It's worth further investigation, visit: http://www.ultrabeam.it/ultra-beam-dynamic-antenna-systems.html
