OK, I purchased a Samsung SIR-T150 today, a RS double bowtie and an inline amplifier. Absolutely no signal indoors. I am surrounded by some rather tall buildings. I have a small north facing balcony on 26th Street on the west side of Manhattan, so I put the antenna outdoors. I am getting CBS, NBC, UPN, WB and PBS, but I have to move the antenna around to get these signals. No luck on ABC or FOX. Would a larger outdoor antenna help? If so, what model is recommended? Can't be too big as my balcony is small. Thanks.

Not sure of your distances, but do you need the amp? I live more than 40 miles from the towers with not the best surrounding terrain between me and the towers. I did not need an amp even through 75' of wire and 2 diplexers(Large Rat Shack antenna in the attic). I did install a rat shack amp I had around, to help with a FOX channel that was weak. No luck. I then purchased a Channel Master amp (12dB UHF) and it worked like a champ. Personally I think the Rat Shack amps are junk. I am also wondering if you are overloading the STB front end with the amp.

Jin, unless you are on a very high floor, your reception outlook may not be too good. I used to live on the 8th floor on 34th street and I had to move my 13" inch set from room to room to room trying to maximize my reception in the pre-cable age. The basic priciple of huge buildings in the way should stille apply to DTV reception I'd think? It's like being in a mountain valley unless you're in one of the taller buildings and high up. Good luck with it!

Andy, the STB was showing no signal until I plugged the amp in. I am only a couple of miles from the transmitters, but no line of sight.


Do multipath problems show up as no signal on the STB meter?

I'm roughly 15 blocks North, on the eastside, also facing north and sandwiched in by buildings (6th floor). A bad reception area. I found the Silver Sensor worked here after the WTC went full power. The Sensor has a very narrow acceptance angle, so it's good at rejecting multipath signals. Suspect it's tough manipulating an antenna for each channel without a multipath indicator. My Philips RPTV displays about five types of tuning indicators on screen, which aids tuning. But it's still a pain. The Sensor is extremely compact so I keep it atop my RPTV, then outlined the best antenna orientation for each station with a grease pencil. In general, WTC stations come in while the Sensor is pointed about 110 degrees North of the transmitters. -- John

Rachael eluded to this, but yes multipath is a problem with the digital transmission medium. I remember reading several articles a few years ago on problems with 8VSB in city environments because of the buildings. Sorry I cannot be of any help....

Thanks for the responses. I doubt the Silver Sensor will work for me, as I get nada indoors. The bowtie is able to pull in signals when I put it outside. What perplexes me is that I can get signals from both the ESB and the WTC, but not all stations on each. I finally got Fox to come in, but no luck on ABC yet. Since the bowtie seems to work, I was wondering if a larger but similar design would help me.
