I apologize for making this about TV reception instead of radio, but I
did not know where to turn. I live in Connecticut, about 100 miles from New York City, (102 miles by the lattitude-longitude charts) and I am about a block from the water, Long Island Sound. I grew up in New York and am a NY Jets and Giants fan, which is broadcast from the Empire State building. The Giants' games are carried by one network, but the other Connecticut stations only carry Patriots games, not the Jets. The Jets' games are carried on channel 2 New York, which is 102 miles as the crow flies from my house. Football packages on satellite TV are beyond present financial condition. I only care about channel 2, New York. Does anyone have any ideas for a quick rooftop antenna I can put on a pole and run into my house for the Jets game? I really don't mind if the signal is somewhat snowy as long as I can make out what is happening on the field-beats radio. Besides, this is football- sometimes it snows for real and nobody complains, lol. Anyway, any help would be greatly appreciated. PS: I have seen websites for dipole antennas. My second question is: If I make a dipole antenna, what if I mounted it on a piece of cardboard or styrofoam for it's length, which cardboard or styrofoam has aluminum foil on the reverse side? The aluminum foil would not contact the dipole, and be separated from it by one quarter to one inch, depending on material thickness. The reason I ask is if this will cut off 180 degrees of reception, thereby improving the signal to noise ratio, (I know a little about electronics as an audio hobbyist, but very little about antennas even though I have tried to get a grasp). |

I thought all VHF television transmission will be discontinued as of February 2009. Building a VHF antenna would seem to be a wasted effort. You need to think how you can receive the same station on UHF digital. There are plenty of UHF antennas available; you may also need a low noise, mast-head, pre-amplifier to get a good signal.

Quick would be a rabbit ears set on the roof. Space your reflector at some distance so that your antenna and reflector look more like an H. What you really want though is a Rhombic antenna. Google that. It is a diamond shaped wire antenna with some real gain. |

Hi Joe, The long answer is No. The short answer is that with the transmission antenna at 1250 feet (give or take), it sees out to an horizon 25 miles away. An antenna on the ground there would receive its signal, but you would have to lift it as you pushed back. By the time you pushed back another 25 miles, that receiving antenna would also have to be 1250 feet in the air. That is only 50 miles range for a very unlikely audience. You are challenge by an additional 50 miles, which, from your perspective, places the top of the Empire State building beneath the earth's surface by a considerable depth. No amount of amplification will rescue that situation. 73's Richard Clark, KB7QHC |

Hi Joe, If you are a betting man, this frequency has a reputation for world wide reception.... if. It is an exotic topic, and you might astound yourself with seeing the game, but don't invite the crew over expecting to happen. The odds are strictly for Vegas as this exotic topic is called tropospheric scattering, or ducting, or meteor shower DX, or any other number of long-shot methods. 73's Richard Clark, KB7QHC |

Easiest and probably the cheapest is to buy a radio shack deep fringe
antenna. A chimeny or Eve mount should be the easiest, it not feasible a 20 foot piece of 1" steel pipe would do nicely. I got denver stations in cheyenne in the 50-60s with a winegard antenna on a 20 foot pole. Transmitters were on lookout mountain or so I was told..... Channel Master and Wingard are two other great tv antenna manufacuters. "JoeSch" wrote in message ...

The reason I ask is if this will cut off 180 degrees of reception, thereby improving the signal to noise ratio, (I know a little about electronics as an audio hobbyist, but very little about antennas even though I have tried to get a grasp). First of all, don't introduce any other metallic objects (foil, etc). Just the elements described below. You need to make a basic yagi antenna. When finished, it greatly resembles a TV antenna, except the elements are all nearly the same size, optimized for Channel 2. (Neglecting the fact that WCBS digital TV is on a UHF channel. You asked for analog WCBS-TV, Channel 2.) Fabricate a folded dipole for 57 MHz out of regular TV twinlead. He http://www.wfu.edu/~matthews/misc/dipole.html Looks like he uses Channel 2 as an example -- convenient! He says it's 2.5 meters long -- I think that's about 98.4 inches Probably should mount it on an 8-foot piece of 1 X 2 wood to keep it straight and level. An inch or so will stick out at the ends -- no big deal. It will go on the roof, mounted crossways on another piece of wood called a "boom" which is aligned to New York City. The folded dipole's position on the boom should be about 2 feet from the end that will be away from New York. That is the active or "driven" element of the yagi and it needs some helpers. The helpers are made of ordinary metal tubes, but have no direct electrical connection to the driven element. Old aluminum tubing is fine. Assorted pieces of old TV antennas will work if the pieces are tightly fastened together and carefully cleaned at the attaching points for a good connection. One helper is called a "reflector" Make it 6 percent longer than the driven element and mount it on the boom behind the driven element (away from New York) by about 21 inches. Next helper is called "Director #1." It's 1% shorter than the driven element and it's mounted on the boom 21 inches in front of the driven element, toward New York. Next helper is called "Director #2." It's 8% shorter than the driven element and it's mounted 37 inches in front of Director #1. You can add more directors, same length, same spacing as #2, but they won't capture a lot more signal after the first few. Plus, with more than two directors, the boom gets really, really long. Note that this antenna is a 300-ohm antenna. Since your TV input is probab ly NOT 300 ohms, you have to transform the impedance to the 75-ohm coaxial cable that plugs into the TV. Do that near your antenna. What I mean is this: Have only about a foot or so of 300 ohm twinlead coming down from the folded dipole. Connect a 300/75 ohm transformer or "balun" at that point and run coaxial cable the rest of the way to the TV. Much better for interference rejection, especially at Channel 2. Such 300/75 ohm baluns are available at all radio stores as well as many variety, drug and department stores. Buy whatever one you think you can connect with the tools at hand. You may have a balun or two that came with an old TV or VCR. The first one of these I ever helped build was made with coathangers on a broomstick for Channel 13. (Higher freq meant smaller elements -- easier.) It worked fine. Let us know how this works for you. I'm interested to know if you were able to follow what I wrote. |

Regards, Frank hmm I thought not all the channels will necessarily change meaning some of the vhf stations will still be there just switching from analog to digital? i have received some tv stations from about 100m away from nyc in the catskill region, perhaps the natural elevation helped but in that same area of ct i have also received ch 2 using regular antenna however receving the ny ch wasn't the problem the closer local ch 2 was more of an issue so pic wasn't perfect i used a regular but large radioshack antenna and coax |
