Any ideas on my dilemma would be appreciated.  

I have a couple of 3L 40M yagis that are stacked at 150' and 70'.  They are 
gamma matched (will change to split feed in warmer weather) and are switchable 
(upper, lower, both) with using an Ameritron RCS-4.  The power split is good 
but I have yet to see an instance of a station that was better using both 
antennas as compared to the top one.  In some cases they appear to be the same 
but the two together are never noticeably better.  

Is there any possibility that the RCS-4 is causing the problem with whatever 
scheme is used to apply voltage in various configurations through the coax?  

Am thinking seriously about replacing the coaxes this afternoon with long 
enough ones that I can wind an RF choke at the feedpoint to each antenna and 
also replacing the Ameritron with a high quality Transco switch I have laying 

Any feedback would be appreciated, especially if someone has reason to believe 
the problem is in using that RCS-4.

Stan, K5GO
