These results are not exact, but they will help set the expectations. Visit TV Fool, enter your street address and get the TV Signal Analysis Results. In the end, what TV stations will you receive?To get started, lets set some expectations. Before you spend hours researching antennas and an hour or 2 building one, it would be good to know if all that effort will be worth while.

Almost all of the transmitters were SSE of my location between 150-162 degrees, except a PBS station at 127 degrees. The interesting part for me was the direction to the towers. I think that means a directional antenna without an amplifier will get them. Almost always, that is true, unless going higher puts an obstruction in the way of the signals.For me, 13 channels were green. Unsurprisingly, the 20ft report showed more stations than the other reports and with the results being related to height above ground. A list of TV stations, channels, power and directions was provided with green, yellow, pink and grey background suggesting which stations I could expect to receive with different types of antennas.
I believe that translates into a specific type of antenna.Based on this research, I’ve decided that the work is worth the effort. TVFool has most of the stations I hope to receive listed as either 1-Edge or LOS (Line of site). If an antenna without a rear-reflector can be used, then I should get Ion as well.I’m about 16 to 25 miles away from the transmitters. The great thing about that is that transmitter is almost 180 degrees off most of the other channels.
Large hills, mountains and/or trees in the way How strong the channel signals are to your location Whether all the transmitters are generally in 1 direction or if you are surrounded Where you are relative to TV transmitters This is dependent on a number of factors like:
I don’t expect that to work.But there are problems. This is in an ideal world. The list and radar map of TV stations near me shows about 20 that I should be able to get with a simple HDTV antenna, with a slightly more complex antenna, I should get 8 more and with a powered antenna, an additional 8 channels – one of them 84 miles away. Outside – May have HOA rules against weather, wind, lightningAs an example, my location is NW of Atlanta near Kennasaw, Georgia.
Sorry.I was prepared to test a few different antennas, so I setup an upstairs bedroom with a TV and antenna area. If you are in the middle of town, surrounded by transmitters, I can’t help much. You know, the rabbit ear and bow-tie antennas they used to give away with the old CRT TVs? Those only worked for a very few channels and I was completely disappointed.Chances are if you are still reading, then you are having issues too. Most importantly, I already tried the cheap antennas around from those older TVs. Further, the other stations that aren’t within a few degrees are either about 15 deg off or 180 deg off, so a directional antenna without a rear reflector can work for me.At this point, I’ve already done a little research and I’ve heard about a few DIY antennas that will probably work for me. In my case, most stations are within a few degrees of each other, so a directional antenna isn’t a bad fit.
When placed near the top of the window, this pulled in about 21 channels, impressive. It is about 16 inches tall. Pole antenna that came with a Haupauge OTA/ClearQAM tuner. VHF came in well, but UHF didn’t. Rabbit ears + bow-tie antenna – about 3 channels were pulled in.
Hanger AntennaSo about 6 months ago, I saw an article about building an HDTV antenna using clothes hangers. It performed worse than the pole antenna, much worse, perhaps 5 channels.So these attempts had not worked as well as I’d hoped. “Aluminum foil antenna in a box”: I built this in about 45 minutes.
These are directional, and single direction if you add a reflector. This version reaches about 30 miles, tops. This antenna is known as a DB4 or an M4 antenna. Some important things they don’t really say:
5.75 inch element spacing (5.25 in may be a better choice) They were pretty cheap.I followed these dimensions (things I’ve learned after this build): Rather, I used the smallest steel dowels from Home Depot. Build and Results – Hangar AntennaI didn’t use hangers. I built this hanger antenna. There are better antenna models to build than the coat hanger for the same effort.I didn’t know this last point – I’d heard it, but didn’t really believe it.
Be certain to read all 3 pages.The phase line, whiskers and screw connectionsMore plans for a simple DB4 Antenna. The best dialog that I saw is here. There is lots more to know know, I started reading antenna forums. None of those changes mattered much.This antenna wasn’t getting PBS or NBC and it wasn’t going to …. Huh? Isn’t this supposed to be better? I played around with the location of the antenna a little and made notes about which channels were received. Using a pole antenna from a USB HDTV tuner, I’d gotten 21 channels.
There are a few other VHF channels too, but I don’t care about those. I normally wouldn’t care, except NBC and PBS stations here are in the Hi- VHF range. The whiskers simply are too small to receive them. The small DB4 antennas like the coat hanger design will not get any VHF channels. Most HDTV stations frequencies have been moved into the UHF band, but a few are in either Lo- VHF or H- VHF still. These are supposed to make it easier for consumers to understand.
See how this mapping doesn’t make sense? Your antenna only cares about the real channels, not the virtual channels. CW ( WUPA) is on channel 69.1, but really at 43.1 UHF. ABC ( WSB) is on channel 2.1, but really at 39 UHF. CBS ( WGCL) is on channel 46.1 on the TV, but really it is at 19.1 UHF. Remember, these channels don’t map 1-to-1 to the station channels advertised and they don’t map sequentially either.
It appears spending $50-$150 is normal for an antenna. Most of these posts seem to be around buying an antenna. Next Antenna Build – a Better DIY Model DB4 Antennas Materials and DesignsI started by reading the Help with Reception forum at TV Fool.
If you even slightly handy, building your own in about an hour is pretty simple.There are some really important considerations when building an antenna.After my attempt building with steel dowels, I found that for an indoor DB4 antenna, solid copper wire is better. It will be better for an attic or indoor solution. However, you can build an antenna, similar to the CM4xxxx for less money and select a design that is tuned to your specific needs. It is well made and for $80, a good value compared to paying cable almost $30/month for 15 channels. The response should help you determine which antenna and whether a DIY or purchased antenna is best.The Channel Master CM4221 series seems to be the standard. I kept reading.If you post your TV-Fool analysis link to the forums and ask for help, someone seems to respond.
It was $16 for 25 feet – my design needed about 20 feet total, so I have over 3x more than needed (three wires per foot). I bought the 12×3 version – that’s AWG 12 (12 gauge) with 3 solid core copper wires. Home Depot or any hardware store, sells something called Romex.
While watching TV, I stripped the outer yellow plastic, thin cardboard and then the normal plastic covering from around each wire with a wire stripper.The spacing between the whiskers matters a little.
