At the moment I am building a array of DX-420 collinear antennas. I have 4
each of the DX-420s (20 ele) Giving me 80 elements. At present I have an
frame that stacks them as such..

A bay of 4 antennas, with a height of around 9 feet, about 5 feet wide on 2
cross booms, one at the center, and one across the bottom area. I didn't
see a need for a 3rd across the top as the arrays are small and not much
wind load. the bottom give it a little more stability and keeps the 2
stacks in line with each other. While standing back and looking at it. I
had thoughts of running them side to side instead.. Such as this

This would give them less height while on top of the 60 foot tower and
cause less strain on the hazer,rotor,thrust barring, etc I assume.. Anyone
have comments on the alternate layout ? Pros, cons ? Suggestions ?
One another note, I have 80 eles for 220mhz also that I have no use for and
had thoughts of converting them to 432 mhz ( to small for 144) this would
give me 160 eles on 432 to play with. This would most defiantly have to me
a 4X4 stack I assume..

The 144 array is next.....
