College Park, MD: What is my best antenna strategy? Omni directional?

I have rabbit ears + loop antenna close to the window, and I pretty much pick up all the channels in green here:

http://www.tvfool.com/?option=com_wr...e1c630fac8aca0

(also attached)


Which is good. But I'd like two things:

1) Move the antenna away from the window where the signal will be worse (i've tried this, and channels start dropping off)

2) Get a few more of the channels in the red/gray area.

The problem is the signals look like they're coming from almost every direction. So what would be the simplest strategy to achieve decent reception? (what kind of antenna is best for what I'm trying to do?)

Where's the new antenna location going to be? Indoors, attic, outdoors, roof? If indoors there was a recent thread regarding a GE Antenna that would probably provide what you looking for and because you have a good tvfool report with strongs signals, even though the GE antenna is technically directional, I could see it picking other signals. Worst case buy two GE antennas and combine the signals.

You're not going to be able to receive stations in gray and probably not in red without a good outdoor antenna on a rotor for the multiple directions. Any station listed as "Tropo" will very likely not be received no matter what you put up.

Nice stacked arrays in your avatar! Is that just for TV or is there some 2 way radio?

Hello, We really need more info. Are you in a house or apartment? Do you have an attic or crawlspace? If so you could put a small outdoor antenna like a bow-tie type there.
The good thing about the channels you will get is they are almost opposite from each other. Since several of the closer ones are in the south west I would point the antenna towards the north east group and since most antennas don't have the best rear rejection the SW stations would come in pretty strong.
The great thing about the digital stations are that they either come in or they don't. There is very little in the way of weak reception. The picture should be clear and static free or gone completely.

The tower is for ham radio. It was just a good place to put the TV antennas.

Please put YOUR LOCATION in the TITLE of all antenna threads. See my edit.

NOTE: Put YOUR LOCATION in the TITLE of ALL antenna threads & TVFOOL info in 1st post

Walking the fine line between jaw-dropping and a plain ol' yawn.

I approached this thinking I needed to put something on the roof, but when I started looking at the graphs on http://www.hdtvprimer.com/ANTENNAS/ for outdoor antennas, I realized they're directional and wasn't sure what to do about different channels coming from different directions.

But the truth is, if I can get away with just having one next to the TV, it would probably be a lot simpler to set up.

House with an attic. Bowties are directional, right? If I simply move what I have now (goal #1 ), will I get good results with just adding a pre-amp?

The main reason for a preamp is to overcome loss between the antenna and the TV. An indoor antenna with a short coax run going to one TV has little loss so a preamp won't get you much.

Based on what I'm hearing here, the first thing I should try is to get some kind of attic/directional antenna, and test pointing it either to the SW or NE.

You could get a DB2e, add the optional VHF kit, pop it up in the attic aimed at Baltimore, and you should get all the BAL and DC stations.

The higher the better, while it might be a bit more extra work, the effort will be well worth it. You'll probably even end up picking up channels you didn't have before.

Where do you find the VHF kit?

The newly available VHF kit is available directly from our website.

Thanks.
Most of these antennas don't have really good rear rejection figures, meaning that an antenna design has the ability knock down signals coming in from other direction besides the front. From the reception report many of these stations transmit from fairly short distances. Obviously if you are trying to get some of those station that are farther out you will need something turn-able on the roof. The ones listed as Tropo you will only get when there is a specific atmospheric condition call tropospheric ducting when signals from far away stations can be received. You might have experienced this on your car FM radio when you might hear Philly or New York stations competing with your local ones.

I'm trying to compare the ClearStream2 with the GE and DB2E above. Is there a place I can get similar graphs as this:

http://www.hdtvprimer.com/ANTENNAS/ClearStream2.html

I saw that there is a ClearStream2 package that includes mounting pole and VHF dipole.

Ok. I think I'll be happy if I can get up to that first light red entry which is listed as real channel 30, virtual channel 30.1

By the way, why does real channel 30 also have an entry listed as virtual 49.1 which is much weaker than the previous real channel 30. I thought real channels would be the actual frequency for that channel, and virtual channels should all be roughly within the same range.

The Clearstream 2V sold at Walmart and Best Buy may also work.

I don't think you'll be able to receive 30.1 WNVT, since WGCB-DT will probably interfere with it. Looks like MHz Networks is also on WNVC-DT 30.1(real channel 24). That one has a stronger signal & should be easier to receive.
