![]() "tg" wrote in message ... I'm a newbie upgrading to a 3GHz scanning system so I'm no looking round for recommedations and feedback on antennas that perform up to 3GHz. I would rather spend extra for a professional level antenna than go for a cheaper option. The AOR DA5000 looks good but I'd appreciate any tips before I start shelling out money. I'm currently scanning with a D130 discone which works well but it only goes up to 1300MHz. Thanks for any advice. You will be lucky if you pick up ANYTHING worth listening to above 400Mhz R I choose Polesoft Lockspam to fight spam, and you? http://www.polesoft.com/refer.html |

I didn't ask for advice about what's available in the upper spectrum, I know what the score is there so let me worry about that. With an attitude like yours maybe you should just stick to your transistor radio. |

Search google for homebrew, parabolic and, of all things, wok! Most of the pages that you'll turn up concern wifi however the antennas that are shown can be easily modified. Also search on the pringle can antenna. Good luck and, despite the whingers, have fun with your hobby. Timfy |

You will be lucky if you pick up ANYTHING worth listening to above 400Mhz R There's alot around 400-500 as steve terry said in his reply, and around 800-1000 there's alot of analogue repeaters, shortrange stereo wireless/headphone, and cordless phones. |

I could also comment on the antenna question,
personally I mainly use the Dressler ARA-2000 active antenna but a good discone with a low noise preamp would be just as fine. Preamps are usually required on high frequencies due to signal loss in the cable, so to overcome the noise you'd use a preamp. (well, technically you use a line-amp. to overcome the cable loss and low noise preamp to increase sensitivity) I'd go with active antennas for any UHF reception. 1GHz (microwave) you mainly use directive antennas, dish and/or horn or yagi is most common and very effective, though very narrow band, you won't find anything to cover 1-3GHz, you'd probably not have more than 0.1GHz span using a helix so you'll need an antenna for every purpose..... //Greg (excuse me for improper pronunciation and/or formulation, I'm not from UK, I'm swedish ![]() |

You can spot these on masts by the horizontal plastic tubes pointing outwards, these contain a long Yagi. The small elements for these wavelengths are more affected by wind & rain, hence the protective tube. AFAIK these carry plain FM voice if it's a single-channel link, multi- channels using subcarriers also exist. |
