After installing my first HF attic dipole and noticing that I can hit Alaska and the Carribean really well and can't hear New England at all, I decided I want another that is perpendicular to it (then maybe I'll hit New England and Arizona... and Hawaii!).
I decided to do this antenna a little differently. Consider it an experiment. While I went to a lot of great lengths to put traps in my prior antenna (which shortened it's length considerably), I decided on this one I want to try window line and see if the interference problem caused by my plasma TV is different. If not, I may be off of 40 and lower until I replace the TV with an LED TV.
Since the window line will be going down along a ventilation shaft that's pretty large, the one concern I have is that I can't put metal conduit in the shaft (one thing I wanted to try was to put a grounded metal conduit in the ventilation shaft and see if that fixes the interference problem).
So anyway, the pictures are below.
