I have no doubt that this is the place to go if you're a hardcore radio fan.
I started reading this group in hopes of finding out how to pick a better antenna for my RadioLabs-modded Sangean 909, but have to admit that I've come away more confused than ever. To keep my needs simple, I need an external antenna for a wide range of bands (between 150 and 30K KHz) that mates with my RCA jacks. I've read about the benefits (or necessity) of a separate antenna tuner, and some brands have come up. I've heard about the Sony AN-1, but found that it's discontinued and Ebay may be the only source, and there are some other loop antennas that I cold lay out on my roof...but I guess I don't know what's best. What thrills me about listening to my radio is picking up signals from all over the world, finding out what other people think and say. It was always cool to me, even when I was a little kid and sat around an old Sony FY-410 worldband radio (which I still have, and it still picks up plenty nearly 40 years later). I don't plan to ever transmit--it's a passive sport for me--and I live in Central New Jersey (USA) so there's plenty of noise to compete with. So, can you hook a brother up? LOL |

LOL My recommendation is a random wire with a coax transmission line. Use 75 ohm "cable tv coax" as impedence isn't an issue, the loss is as minimal as RG-8 type cable and you can't beat the availability & cost Radio Shack sells an 'F' to phono plug adapter if you don't want to fiddle with soldering the phno plug to the coax. For a proven method of how to minimize noise the following article is a 'must read': http://www.anarc.org/naswa/badx/ante...e_antenna.html You will find many other useful ideas if you browse many of the articles on the 'parent' site http://dxworld.com/dxnews.html#ANT and then for even more info on shortwave, and broadcast band monitoring, the 'grandparent' site http://www.cybercomm.net/~slapshot/speedx.html is highly recommended. As to the tuner, or preselector - different animals though some use the terminology interchangeably, I'd hold off on worrying about using one. A tuner matches the impedence of the antenna to that of the radio, whereas a preselector works as a bandpass where it rejects signals outside the frequency where it is tuned. First order of business is to get the antenna installed, pay attention to grounding, keeping the antenna clear of powerlines (can be hard in a city, if possible run the antenna perpendicular to the power lines, it can help to reduce noise) and when routing the cable into your home keep it as clear of the household wiring as possible. There ya go, all "hooked up" Howard |

I've heard about the Sony AN-1, but found that it's discontinued and Ebay may be the only source Buy the cheapest Ham radio antenna tuner (especially without meters you don't need). Used is OK (as long as it isn't burned out). , and there are some other loop antennas that I cold lay out on my roof...but I guess I don't know what's best. A long wire as high as you can get it will fill your bands. A loop may be more useful for AM DX.

Hi OM, For that anticipated noise: search the archives of this group for "chokes" for antennas, also use keywords like "ferrite" and "1:1 Balun." 73's Richard Clark, KB7QHC |

Hi there,
I had a Sangean type Roberts RC818 as my first radio, that was a great performer. For HF listening, you cant beat a longwire!! Run the wire as long and as high as you can! Match it to the receiver using either a cheap RX only ATU or a Magnetic Longwire Balun ($ 25-ish). There is NO NEED for active antennas, there is so much signal on HF, and your receiver is sensitive enough to work with a little telescopic. A properly matched long wire will haul the signals in... John. |

Fantastic response, guys! I knew I came to the right place. It seems a
longwire is the way to go, and I'll be using your advice to make a go of it. Thanks again! |
