Would a discone cover all the US TV broadcast Freqs?
I want to put up the smallest outdoor antenna that would cover all TV
Broadcast Freqs being used after Feb 2009. The log-periodicals are too "un-stealthy" to go unnoticed by the XYL, but I think a little discone with some black paint might escape her inspection as long as I do the installation while she's out shopping. Question is - have any of you used one for TV - and if so, how did it perform? would it cover the TV broadcast freqs ? (I'm aware of its lack of gain - I'm within 5 miles of most local stations, and within 20 miles of a couple more.) Thanks Hal W4PMJ |

Multipath with digital signals does not produce ghosting, just signal degradation, although it can be so bad as to make viewing spotty with dropouts. I'd give it a go if I already had the antenna.

Results in a 15db or more loss in signal. |

Years ago I lived in a townhouse apartment that had cable but you bought it through the apartment at a premium rate compared to the cable company. I put a coat hangar dipole in the attic and connected it to there wiring. I got ABC, CBS,NBC 3 PBS stations and a couple of local non affiliated stations. Way more TV than I wanted. |

How about a dual-discone mounted horizontally? AKA a Bi-Conical.. Seems like a waste of a perfectly good pair of communications discones, to me. If the original poster is looking for a low visual antenna in place of the sometimes large TV Yagi's, he might take a look at antennas made for the RV industry. Personally, I'd homebrew something out of brass welding rods..... perhaps a few stacked horizontal loops...... Ed K7AAT |

So - does anyone know of an omni directional horizontally polarized wide band antenna? |

So - does anyone know of an omni directional horizontally polarized wide band antenna? Had something like that on the roof of my RV. A Wineguard Roadstar 2000 omnidirectional antenna ought to be just what you're looking for. Paint it black, if you want even more stealth. such as at: http://www.amazon.com/Canon-Winegard-Roadstar-2000- Antenna/dp/B000R2YB0G Ed |
