omnidirectional horizontal antenna is there such a thing? I have an all aluminum 5/8 wave antenna up about 75 feet, and was wondering if there was a horizonal omnidirectional horizontal antenna. I have been looking at the Y-Quad antenna simple because of its size. Any suggestions? Thanks, Kevin |

Horizonal antennas are bi-directional. They transmit and recieve broadsides to the dipole or elements (unless you have a reflector and then it is one way. You could put up two dipoles facing different directions or put up two horizonal elements facing two different directions. You could put one horizonal copper element tuned to your frequency on a rotor and it would serve you well. mikefromms |

im thinkin of doing a phased dipole cross polarization setup with the horizontal dipole on the top with a rotor. this should help reducing fade when talking DX and figuring my a-99 disintigrated, i could use a new and better antenna |

There are no easyily constructed horizontal, omni antennas. You can build a loop antenna out of wire (1005/freq in mhz =feet and feed directly with coax/trim or add wire to loop to minimum SWR) and you will hear somewhat on the side. BUT the signal will not go sideways. You will transmit an indirect omni signal by bouncing the signal off the atmosphere strate up and having the signal reflect strate down--turn a V upside down and that will be your signal pattern. The distance of such a cloud burner antenna is usually only a couple of hundred miles though. Signed That ELCO Guy |

Yes its called a squailo |

Thanks guys for the response so far! I would love to setup a horizontal antenna which I could use for late night/early morning ground wave contacts. In fact since space is limited here where I live (my covenant doesn't allow masses on the house) I'm thinking of maybe setting up a stationary antenna or dipole and face it in the one direction I want. There are several stations to my north that are around 100 miles away that I know, and would like to talk to more often. Would a dipole give me the ability to reach them? Some of these guys have beams and use the flat side. Thanks Kevin |

ive found in most cases a dipole blows the antron 99 outta the water on vertical. i dont see why you wouldnt be able to reach em other than geography. another thing you could do is get a phasing harness for the dual mobile antennas and space 2 horiz dipoles around 1/4 wave apart on whatever you use for a mast. that will give you more gain since it will radiate more power to the horizon rather than into the clouds. |

100 miles is a stretch on most bands ..... you got to love deed restrictions ..... give it a try!

Try Squalo's,crossed dipoles fed 90 degrees out of phase, fullwave loops or a DDRR (check ARRL antenna Handbook or send me your email and I'll scan a email the data to you) |

Spun, The "Squalo" antenna everyone refers too was made by Cushcraft Corp. in the 70's and 80's. They made models from 40 meters HF through 450MHz UHF. This link describes the antenna basics: http://www.g3ycc.karoo.net/squalo.htm You should be able to adjust the 28MHz version to work on the CB band.

Thanks Mr Rf. I'd love to put up beams here but I can't. The dipole idea may work, who knows. Thanks. Kevin |

thiers another dipole variant where the whole thing is shaped like an (S). this is also suppost be be omni directional and in the horz plain. |

Hey anyone remember the saturn that Avanti made back in the 1970s and 1980s? It was horizontal and verticle omni! Ive only seen one ever and it was up on the roof of a gas station/garage somewere in Western NY state.... Only one ive ever seen besides those in my old Avanti cats...... |

There is such a thing as an omni horizontal antenna. Jampro has made them for years. Keep an eye out for the new Copper antenna. It will satisfy this requirement well. |
