If  you had the freedom you apparently want, so would your next door neighbor, the one who aspires to be a pig farmer.

I am in a rural setting (black Angus ranch) with no one to answer to re my towers/antennas except the FAA and my nearest neighbor is 1/4 mile away. I don't have to make many compromises about my structures or their appearance as in 20 years I have pulled one permit, a septic system install. No mechanical or electrical inspections or permits for houses or outbuildings. My only defense in case a neighbor wants to start a pig farm is distance. Distance from my house to various neighbors varies from 1/4 to over 1/2 mile.  Luckily my neighbors are cattlemen not pig farmers. Townie hams have my sympathy as they may suffer mightily at the hands of the petty little minds in positions of power and control over the actions of others.  The theory sounds good, protection of property values and aesthetics, but the practice is not always fair.

It’s so nice to live in a free country…

SO2R is still feasible with the proper diplexer as long as the two operators 
can work stations in the same direction. This antenna's beamwidth is 70 
degrees, so there is plenty of leeway geographically.
A hard-fought county variance was required for this antenna. Multiple towers 
would have been right-out.

I can see the attraction of a system such as this to government, where a single 
antenna to cover all of HF might be needed, but in an amateur station, it seems 
like a ton of money putting all eggs into one basket. One clamp failure and 
your entire antenna system is a crumpled heap of aluminum.

Perhaps one tower is all he had space to raise, but it also seems like a huge 
sum of money to not even get SO2R capability.

Cool project to follow in the photo essay, and condolences on the final result, 
sincerely.

The antenna and tower design was fine, we had over the years installed quite a 
few of these systems from Sabre, Hy-Gain, Rockwell to US Antenna and never had 
a failure.
It was unfortunate that the clamps were not torqued to spec.
Reading from the projects start there were issues with the pressurized line etc.
These tilt over LP’s are made to do this along with that tilt boom bracket.
Cable crimp’s were never used on these turnkey LP antennas that we had 
installed and the rotation system has been pretty much standard.

That is a bad idea, the torque force on the rotor under high winds will become 
much larger.

##  with  more  boom on the  shorter ele  side.....vs  the   longer  ele  side, 
the required  rotor
torque  will  be  sky high.   They  have  mounted the  boom  at its   CG.   
They  should have
mounted at  center of  boom,  and  added  a counterweight  at  light  end  of  
boom.
