To all,
I am installing a elevated 40 meter 4 square over somewhat marshy New England soil. 

My property backs up to a drained 30 acre pond. You can see my QTH on Google Earth. It's the house before the property with the greenhouses.

Base elevation is 20' above ground utilizing 2 -  Rohn 25 tower sections per element. Elevated ground plane. 

I wish to use 3/4 wave phasing lines instead of 1/4 wave phasing lines so I can dress the phasing cables down the tower legs and underground to the Comtek box. 

The Comtek manual states to use only 1/4 or 3/4 wave cables and I understand that. 

Has anyone observed any determent in using the 3/4 wave cables vs. 1/4 wave cables?  

I am not worried about cable loss as that can easily be overcome at 7 mHz. 

Please don't tell me cost...after starting this project, cost has gone out
 the window ! 
Now it is just get it done without any problems. 

All hints...ideas welcome. I will use whatever fits my situation to make the system a sucess.
