Capacitance hat on the edge of the fiber rod and5cm width balanced feeder which is 10m long. The other side of the element with capacitance hat. This antenna is instaled between the center of cubical quad  Structure of V type G5RV 2 of 4.5m length fiber rods,. 2 spiral alminum elements(2mmφ 10m long) attached on the rods with capacitance hats. and 10m lengh balanced feeder from the center of anetnna to bottom. 1:9 balun and AH2 antenna tuner. I mainly operate from 3.5MHz band to 10MHz band by this antenna system. This antenna system relatively receive low noise and good perfomance for DX stations. I enjoy opration from 30m band to 80m band and use cubical quad antennas from 20m band to 6m band operation. 10m length and 5cm width balanced feedr

１：９ balanced - unbalanced balun AH2 antenna tuner, balun and filter of common mode   Above antenna system works well domestic communicationin Japan. And I can almost communicate with outside Japan.
