When I lived in Longmont, CO, in a 1200 sq ft house with lots to match. I had
an HDBX-48 with a KLM KT-34A and a Cushcraft 40-CD2 all rotated by a T2X. I was
stunned that when I gave directions to service people I’d mention the tower,
yet they NEVER saw it until I pointed it out after they arrived. I pointed it
out to one guy who was amazed that he hadn’t seen it as he drove up, parked in
the driveway, and walked up to the house. I was far more sensitive to antennas
than any of my neighbors, mainly because I was always looking for them.
Don’t worry about it: they clearly simply don’t notice it, so count your lucky
stars!
