[TowerTalk] H-frame (more questions)

[w4an@contesting.com (Bill Fisher - W4AN)]

I would like to know how much interaction a cross arm of steel would 
cause an H-frame of 105CA antennas.  I know there will be some degree of 
change, but since the cross arm isn't going to be resonant on 28Mhz, I am 
wondering if the cross arm would effect it that much.

                Ant--------------------Ant
                       <---25'--->

Then is it improved by lowering the antennas at the end of this boom by 
about 5' with another piece of metal?

                   |                  | - 5'
                   |                  |

Any ideas also appreciated.  My plan is to fix this system in one 
direction mounted on a Rohn-45 tower.
