[Antennas] multiband dipoles, leg seperation

Sun Sep 24 15:01:52 EDT 2006

Hello to the group,
I have used full length multiband/legged inverted vee's in the past with much 
success. But in this instance I want horizontal radiation, (not the 120 degrees 
or less apex angle to get vertical radiation) and multiband/legs.
Now I have a slightly different problem. I want to use 3 sets of hamsticks in a 
dipole configuration. I will be using one piece of aluminum as the center for 
all the antennas. The bands covered will be 40m, 30m, and 17m. I plan to place 
one set in the horizontal position, lets say the 30m sticks. My question is what 
angle of separation from each other should the other 2 have from the 30m sticks? 
40m sticks pointing upward at an angle and the 17m pointing downward at an angle.
I'm afraid I'm not stating the question well. if the horizontal sticks have a 
180 degree apex angle. The other two upper pointing hamsticks should be have 120 
degrees between them. And the lower pointing set of hamsticks have the same 120 
degrees between them.
Would that give me enough separation so as to keep the interaction during tuning 
to a minimum and also allow for horizontal polarization?
Could I narrow the separation between the sticks from 30 degrees, to less, like 
say 20 degrees between the sticks and still not have to much interaction, 
causing the whole thing to not work well at all? I figure that would make for a 
better chance to maintain the desired horizontal polarization?
Hope the question isn't to confusing and thanks for all input.
