  • Omni or Bi-Directional

    Hello all, what would be the best choice for installing an FM antenna on my balcony in Manhattan? Should I go with bi-directional or omni? Or just plain rabbit ears? BTW does anyone know the difference between bi and omni?

    I use a $10 pair of RCA rabbit ears out on my back porch (ground level) in Florida, works far better than any indoor antenna solution.

      Actually, I should say, I don't put the rabbit ears on the ground. I place them on top of an A/C unit which is a couple feet tall.

        I use modern rabbit ears with 75 ohm coaxial output cable, not the old 300 ohm twin lead.

          it really depends on your location, (and elevation), location of the stations you're listening to, and what obstructions, (i.e.: adjacent buildings), may be between you and the stations. manhattan is likely a difficult reception environment. in general, if you could point a directional antenna towards the stations you want to receive, this is your best option. a bi-directional antenna (like the ubiquitous t-wire dipole) would also work assuming the stations are in the direction you want to receive. the opposite direction would likely be blocked by your building. which would also likely interfere w/an omni antenna, and an omni in an area surrounded by buildings will likely pick up a lot of reflected and interfering signals. you may have to experiement with different possible solutions.
