Hello all.  I have recently moved to a new home and am planning to set up my hf gear in my bedroom.  I plan to erect a dipole running the coax through the eve and down from the ceiling.  My problem is with the station grounding.  In order to have a short ground path, I would need to drill a hole through the wall (drywall and brick).  I cannot run it through the windows because of my security system.  Any suggestions? Does this sound correct?

Thanks and 73,
