W3DZZ antenna
with traps on toroid cores
W3DZZ is a popular multi-band antenna. I decided to make it with a trap on ferrite cores because of the small size. Traps were made according to pictures and description posted on the sotabeams: http://www.sotabeams.co.uk/antenna-traps-w3dzz-7-1-mhz-100-watts/
Core FT90-2 red, 68pF tubular capacitor cutted with sapphire nail file in order to bring the trap to resonate at the desired frequency.
I connected the antenna to the current balun 1:1 with core FT114-43
The antenna is tuned properly for 80 and 40m, on the higher bands have not good swr, yet.
