Is there a product you can recommend as "The Best Omnidirectional FM
antenna"? If so, which one is it? (brand/model and/or URL please) Oh - one significant constraint is that it cannot be larger than about 3 feet (1 meter) in any dimension, because it is going to be installed in my attic. I know it cuts the signal by 50%, but I am willing to live with that since I am assuming that if a whip antenna on a portable radio works great in my basement, a **good* omnidirectional FM antenna in the attic must work *at least* as good... An extensive search yielded only the Triax omni FM: http://www.towerhillaerials.com/view...&orderNumber=0 But where can you buy it in the USA? I also found an ANTENNACRAFT FMSS at STARK Electronics: http://www.starkelectronic.com/acantena.htm#FMSS, but the specs at that site say Boom length is 8' and Maximum Width say 55'. These can't be feet, right? They surely confused the foot symbol (') with the inch symbol (") - or did they? Anyway, any tip you can provide on finding such an omnidirectional FM antenna would be highly appreciated. VHF/UHF omnidirectional antennas that do *not* trap the FM band with a notch filter are welcome, too. Thanks, Lynn |

Ummmm, look: Here is why answering an open ended question like yours is essentially impossible.
Who has a large financial interest in reaching an answer to this exact question? FM broadcast stations, that's who. For transmitting. But, there remain about a half-dozen manufacturers still in that business, competing, and if one were "The Best", then the others would quickly disappear from the business. For example, Andrew, Dielectric, Jampro, Shively, and Superior are all still in business, AFIK, but are likely too pricey for your requirement. I happen to prefer the Jampro myself. And Richard Harrison may have newer catalogs than I have at the moment. And, when you put the unrealistic 1 meter dimensional restriction on it, then this "Best" description fails totally. -- Crazy George Remove N O and S P A M imbedded in return address "Linux Lover" wrote in message om...

While there are a number of Directional FM antennas, here are the Omni-Directional FM Antennas - that you asked for: The Antenna Craft Model FM-SS (crossed folded dipoles) http://antennacraft-tdp.com/pdfs/FMSS.pdf The Winegard Model PR-6010 (Turnstile) http://www.winegard.com/offair/pdf/pr-6010.pdf Thank you Greg. I guess these are the only available options that meet my "specifications" (omnidirectional, can fit my attic). Between these two, do you happen to know (or have an opinion) which one is better? Thanks, Lynn |

George, thank you for this very informative answer. I was completely unaware of these companies and I can now try to perform a Google search - if only to satisfy my curiosity (if the antennas are too expensive, then perhaps I am not interested in the "best"). As for the "unrealistic 1 meter dimensional restriction", you are right. I actually meant "the best omnidirectional FM antenna within that 1 meter size restriction". Also, if I am lucky I may be able to fit even the Winegard PR-6010 (67" or 1.7m wide) in my attic. BTW, what do you think of a wide 25-1300 MHz Discone antenna as an FM/VHF/UHF omnidirectional antenna (http://tinyurl.com/4anu7). Can this work? (assuming ghosting for TV is not a problem...) If so, is there a solution to matching its 50 ohm impedance to the cable's 75 ohm? Thanks, Lynn |

That and the Antennacraft FMSS are essentially the same so you may just want to choose between the two based on price. Radio Shack used to sell this antenna also, not in the current listings but perhaps a store near you has one left in 'old stock', their price was about $15 less the coax feedline. Forget the discone, it will work - though I can't say any better than the two antennas mentioned - but what you gain in reduced footprint is lost in the discone being taller. Also, you can expect to spend more for the discone. FWIW, I put up the Radio Shack crossed dipole antenna at a friend's cabin and it took him from getting no FM reception to two stations. Okay, not an "FM DX antenna" but consider that he is 40 miles from any town of significance, the cabin is in a valley and there are taller mountains between him and anything else. Good luck, Howard |

Also, you can expect to spend more for the discone. If I can fit it in my attic *and* eliminate the need to have two antennas (TV and FM), I am willing to spend the extra cost (up to $100). I get most of the TV stations that I want through basic cable service. There are two local TV stations that I receive very well with a simple rabbit ear antenna (came with the TV), so my requirements from a TV antenna are not very high. I guess the only questions I have regarding the discone antenna a 1) Are there any issues in regard to wave polarization? Is it true that both TV and FM broadcasts are polarized both vertically and horizontally? 2) How does one match between that about 50 ohms antenna impedance and the cable's 75 ohm impedance? FWIW, I put up the Radio Shack crossed dipole antenna at a friend's cabin and it took him from getting no FM reception to two stations. Okay, not an "FM DX antenna" but consider that he is 40 miles from any town of significance, the cabin is in a valley and there are taller mountains between him and anything else. Yes, that is exactly the kind of result I want to achieve. I know there is no magical solution that defies the laws of physics (50% signal loss when placed in the attic, size, etc.) such as the "bogus antennas" described he http://www.kyes.com/antenna/antennat...ennatypes.html Good luck, Howard Thank you very much!

Lynn - This really gets to the heart of your design and selection question. From your location you need to determine the bearings 0 to 359 (with North at 0/360 and E at 90 degrees), where the FM (or TV stations) transmitting antennas are. Geography and population density usually "clump" these large transmitting towers in a small area. (Chicago - Sears and Hancock skyscrapers; New York - Empire State Building and Palisades (NJ)) The layout of these transmitting antennas in a 60 mile radius will help you select the ideal antenna pattern for your location. Instead of an omni, you may be able to use a beam, if all of the stations (that you really wish to listen to) are in a 30 degree or less spread. Greg |
