[TowerTalk] Adding 6m to a Quad

In planning the addition of 6m to a 3 element quad you have several issues  
to resolve.  First, element spacing is in the 30" to 40" range, so  additional 
element supports will have to be added in between the existing HF  spreaders.  
The other consideration is where is the boom to mast plate located  along the 
boom?  Then what is the potential for mechanical  interference between 6m 
arms and the tower. (one set of arms could be very  close to the mounting 
 Because your quad is an odd element  configuration, you already must have an 
asymmetrical element  arrangement.  Somewhat dependant on you current HF 
element  spacing I would consider the following.    
If your driven element is forward of the mast attachment  point, and about 
10ft separation from the Director element I would use the  Driven element HF 
arms for the 6m Reflector.  Add a 6m Driven (about 40  inches from the 6m 
Reflector, and a 1st director halfway from the 6 m driven and  the HF director 
the 6m 2nd director is co-located.  I am assuming  about 12 ft between the two 
HF elements.

Subject: [TowerTalk] 6M Quad  

I would  like to add 6m to my home made 3 el quad
I have 23' boom and could add any  number of elements for 6m.
I would like to use the 3 el that are on the boom  now, just more for 6m
What software to use for spacing and  lengths?
