What is more important??
Aesthetics or Reliable Reception??
I choose Reliable Reception.
I suspect that moving the CS2v to above the roof in such a manner that reception is not , obstructed , impeded , blocked , by the roof and building in the directions of , South East , East , North West , will provide reliable reception.
Aim the CS2v antenna at about 131 degree magnetic compass direction.
Here is how to aim antenna ,
