View Full Version : All my OTA locals are 73 miles away. Is there any antenna I can buy that will reach? Insomniahead 09-04-07, 10:24 PM thanks in advance... insom EscapeVelocity 09-04-07, 11:28 PM http://www.haystack.mit.edu/images/obs/misa_antenna.jpg EscapeVelocity 09-04-07, 11:36 PM The 150' Millstone Hill Steerable Antenna is located at MIT Haystack Observatory in Westford Massachusetts. This fully steerable antenna was designed by the Stanford Research Institute (SRI) in 1959. It was originally installed at the Sagamore Hill Air Force facility in Wenham Massachusetts in 1963. The antenna was moved from that location to Millstone Hill in 1978. Since that time it has been primarily used as a UHF radar antenna to provide measurements of the near space environment using the incoherent scatter radar technique. It is one of two surviving dish antennas of this type in the world with the other antenna being located at the Stanford University radio science field site in Stanford, California. MISA is used to provide wide radar coverage in latitude and longitude. :) Rory Boyce 09-04-07, 11:37 PM The neighbors might complain about that solution. afiggatt 09-04-07, 11:49 PM All my OTA locals are 73 miles away. Is there any antenna I can buy that will reach? Assuming this is a serious question, depends on the terrain between you and the stations, your elevation, and the broadcast power & antenna height of the broadcast towers. Can't begin to help without a zip code and some info on where you live. EscapeVelocity 09-05-07, 12:12 AM I was just crackin' a joke. :D Kudos to you for giving all us noobs good antenna advice and recommendations. jtbell 09-05-07, 09:19 AM If the stations are at full power and you don't have a lot of terrain blockage in between, you should be able to get at least some of those stations with a good outdoor antenna. My antenna (Radio Shack VU-190XR combination VHF/UHF) can pick up two Charlotte stations pretty reliably at 72 miles, and the two other stations whose transmitters are basically in the same location come in OK in the evening and at night, with spotty daytime reception. Similarly I can get two Columbia SC stations reliably at 68 miles, and two others are spotty (one of them suffers from interference from an analog station in North Carolina). In both cases I have a bit of terrain blockage. The top-performing UHF-only antennas (Antennasdirect 91XG and Channel Master 4228) can do somewhat better, so the ultimate solution is to combine one of these with a good VHF-only antenna (if you need VHF, that is). Feed your address or latitude/longitude to the reception calculator at www.tvfool.com and get a list of information about the expected signals from stations in your area. Focus on the "Rx(dBm)" column which gives the expected signal strength. With a good antenna like the ones in the preceding paragraph you should be able to get down to maybe -110. nybbler 09-06-07, 10:28 AM How high can you put it? In deep fringe areas, an antenna on a 100' tower is going to get a lot more signal than an antenna on the ground, other things being equal. HalfFast 09-06-07, 12:05 PM Depends if they are all in the same direction and check http://www.antennaweb.org/aw/Address.aspx good luck qz3fwd 09-07-07, 11:50 AM That antenna is pretty cool. Where can I get one of those? Buy the antenna and the home is included in the sale price!

It depends, mainly, on line of sight and power of transmitters, and height of antenna. Winegard and Channel Master also have top of the line antennas. You may need a roter for the antenna has to be aimed directly at the transmitter tower. |
