      Yeah, but transmitting and receiving patterns are typically reciprocal --- a directional transmitting antenna will also be a directional receiving antenna…. Some metal in the way of a transmitting signal is also in the way with a signal coming in to be received…

      "because the antenna’s major radiating (and receiving) pattern will be slightly below the horizon and your air duct would block some of that."

      He is not transmitting here in this case...

      > Why not ?? should work fine for most local stuff, but any signals coming in from a higher angle could be significantly reduced (air traffic, for example) because the antenna’s major radiating (and receiving) pattern will be slightly below the horizon and your air duct would block some of that. Most aircraft have antennas mounted on the bottom of the fuselage so they radiate best down and out; antennas at the airfield and other locations have them pointed up so the radiation is up and away.

      > Another idea.... I used a magnetic mount to the ceiling air duct right in front of the window and have the antenna hang upside down. Looks funny, but it works.

      > this may be a stupid question but, I live in an apartment with no balcony and i am wondering if a magmount antenna on the fridge would pick up more than just the normal antenna and if so is there much difference. I appreciate all your expertise
