[TowerTalk] Cubical Quad antenna design

[J. Hector Garcia XE2K]

TT's:

I need a good design  of a cubical  antenna , i want to have in this antenna at least 4 ele in 20m  and 17  , and 5 elements in  15 and 12    if fit 6 ele in 10m .
i have the material from 2 cubex  antennas  a 4 and 3 ele   sum of 7 ele material.  i can use and my tower support a 30 ft   or -  boom .
i will  remplace  my  homebrew 10m 4 ele,  15m 6 ele and  20m 4 ele,   the cubical prove to be better in my city where is very  noisy. this power company only take care of the service not in the quality . here is the result,  20 m   yagi  s7 noise some directions jumps to s-9 ,   cubical 2 ele s2- s3 all directions at most.

i will like a practical design  where dimensions are clear and separation betewn elements, i will have some spare time this summer and i will like to have ready for the next cq ww  contest.   
books, designs  or even a manual what i need to get will be apreciate, i want to have  the professional touch in this antenna.

 p.d  the yagis will be for another location after improving  

tnx in advance  de Hector XE2K
