Multiband EFHW Base Antenna with 49:1 UNUN (Home Made)

CORRECTION: Toroid core is used FT240-43 (not 140-43)
My new home made Multiband End Fed Half Wave Antenna which has been designed mainly for 40M band (7MHz), but this antenna tunes also on 20M-15M-10M without any traps or additional coils. This antenna is made for 100W RF input power and is 19,129m long. SWR on 40M band is 1:1.1 within the phone section and less than 1:1.5 within a whole band. The 49:1 UNUN box is weather proof and all holes for components I drilled were sealed against the water. On the end of the video you can see also an extreme weather followed the next day :D
