Would an antenna like the one in the link be any good? I am looking for a
decent shortwave antenna. I mainly listen to 11.175 USB and 5-9mhz USB. http://www.radioshack.com/product.as...Fid=278%2D1374 Any advice would be helpful. thanks, Paul |

Radio Shack offers a very useful antenna kit for shortwave listeners.
Otherwise, buy 100 feet of hookup wire and rig it East-West and end-feed it to your receiver via any tuners, preamps , matchers or preseleectors and you should be alright. It won't hurt anything if you can only hang 50 to 75 feet, and if you don't have any of the aforementioned equipment, don't sweat it . The higher you can get it, the better. If it slants down, that is beneficial for reducing noise. If you find your receiver is over loading, reduce the length of the antenna. Be sure your receiver is connected to a good ground as that improves reception. Reception has been poor recently. No amount of wire is going to improve that, except to say, that a longer length of wire will receive more energy. Some of that energy is going to be flourescent lights, power lines etc., so keep that in mind. I don't know where you are located geographically, but just go with the flow. I got up at 1:30 AM PDT this morning and heard Australia from 2.310 pretty well, but other frequencies varied - I heard several Ecuadoreans and Papua New Guinea, but the BBC Relay broadcast from Solomon Islands was marred by interference from something I could not identify, and other australian stations from Tennant Creek and Katherine did not fare so well, but Papua New Guinea from Port Moresby did fine; I heard WLO very clearly as well, giving weather synopses. It is all a gift, so enjoy what you can hear S. |

Hi Paul:
It's a nice looking gadget, but 50 - 150 feet of wire stretched e/w & far away from electrical appliances / lines will do much better. I find the 18 - 22 Gage Radio Shack Stranded insulated wire easiest to deal with. You can either hook the antenna up directly to you r whip antenna , or tape it down 1/4 - 2 inches away from the whip if you get " Overload"; - Also disconnect the wire before a thunderstorm , etc.. Look hre for more info on Antennas & DX'ing http://www.hard-core-dx.com/ http://www.hard-core-dx.com/index.php?topic=antennas Dan In article , "Paul" writes: Would an antenna like the one in the link be any good?

I have built lots of differrent antennas over the years, and always fall back on the trusty ole dipole antenna. Now that I have built all my antenna farms and have tired of maintaining/building them, the simple ole dipole is it. After you have learned to build it, install it, you can forget it. Spend your time enjoying your radio and other, as the dipole is all you need. Still listening after 20 years. Drake R8, Sangean 808, Sangean 803A, Sangean 606, Grove TUN-4, ......and down to one last 100' dipole 75' in the air, may it last the rest of my life, I'm tired of erecting antennas! LOL! Kruppt |

Paul,
ON-POINT: For your USB 11.175 MHz a Half Wave Dipole (HWD) is a good antenna but requires a specific length and height for a small band of frequencies and for those frequencies is very directional. * These facts limit the HWD's application as a good overall for the other group of frequencies 5-9 MHz (USB). * You could construct a Dual-Band HWD or Tri-Band HWD Antennas to try and cover these three SW bands. * Usually Multi-Band HWD Antennas are 'cut' for the lowest frequency (longest/largest size). * A type of HWD that uses a single center support with two slopping legs is call the Inverted "V". NOTE: The commercial antenna that goes by the Brand Name of "Alpha Delta" Model "DX Ultra" (80Ft Long / 20-30Ft Center / 5-10Ft Ends) is a Tri-Band Inverted "V" Antenna. http://www.google.com/search?hl=en&i...=Google+Search FWIW: You may wish to consider the a simple basic antenna that incorporates the Low Noise Antenna Design Concepts a la John Doty. http://groups.yahoo.com/group/SWL-AM...enna/message/2 The best shape antenna that lends itself to the Low Noise Antenna Design is the Inverted "L" Antenna. http://groups.yahoo.com/group/SWL-AM...nna/message/10 The Inverted "L" Antenna can be erected at any average Height 15-45 Feet and for any reasonable Length 30-135 Feet to fit your land and space limitations. When constructed well using a matching transformer and ground; they can give good omni-directional coverage across the LW, AM/MW, and SW Bands. ~ RHF .. .. = = = "Paul" = = = wrote in message ...
