Any antenna suggestions for inner city use?

I have line of sight with Sutro Tower in San Francisco, but the Federal Building is just to the left between the tower and me, so I guess I need an antenna that strongly rejects multipath. Might I also need an attenuator due to being less than 2 miles away from multimillion watt transmitters? I have Comcast but they do not transmit the subcarriers of all the DTV transmitting coming out of Sutro. I think 30 plus signals.

Indoor or outdoor?

Guest,

As silly as this sounds, try using a paper clip plugged into your TV sets' antenna socket. Bend it into an 'L' shape or a 'Z' shape and let us know if it works for you. Being so close to Mt Sutro, a 'real' antenna would likely collect so much signal it would overload your tuner. If this works, you could use a coaxial switch to select antenna or Comcast, but you will have to instruct your TV what to look for in its on-screen menu. Good luck! :daffy:

the Antenna is not what rejects the multipath and signal echoes are the turners with the equalizations and error correction system what have to deal and distinguish between the stream with a multipath and a signal fluent the antenna can help but when is correctly installed.

Francisco,

I disagree. Control over the quality of a received signal begins with the receiving antenna. Depending on the design of an antenna and how it is installed can definately control multipath interference. Here is the penultimate example - be sure to look at both page 1 and page 2 on this strangely named website:

nice antenna , maybe should i copy the design, i saw the trick of the cooper wire in a can of something , but i really i do not believe this thing work, well works in the 8VSB modulation but in our system COFDM would really do not work, is just so troublemaker the ISDB-T system than i really am thinking in upgrade my antenna by one with more gain or that can pull out more channels when the channels gets on air, already is just 13 channels on air in DTV.

i hate quote myself but well maybe ok is a mistake, but again later of the antenna is the receiver or tuner what have to solve some problems, of anyway the picture that shows in there is exactly my same problem with position the antenna, my house is inmediatelly not up of 5 meters (16 foots) another house and a little gap and later have more houses and just a little gap to the hill

I've considered a design like the one Jim has linked for enclosing a cut to channel antenna, using the "cage" to block co-channel interference.

For the OP, have you tried anything yet? there are a lot of simple home made antennas that would be great for testing your results. A simple 2 bay "coat hanger" antenna should be good for that.

In the end, you may want to try a small directional antenna like the RCA ANT751:

See how it works, and decide if you need an attenuator and or "cage" later.
