small shortwave antenna
I am livign in an apartment, so I cant transmit (no towers and what
not) so I am looking for what would suit my needs best for HF and shortwave recption in general I have googled a bit and havent found much in the way of easy to build or easy to obtain parts to build antennas any help would be really appreciated cheers |

Hi Squeege,
Check out the Sony AN-LP1. It works very well, and I don't think you can beat it at the size. It's particularly nice with Sony's budget HF receiver, the ICF-SW7600GR. Just stick the suction cup on your apartment window, and you're in business. Ed "squeege boy" wrote in message ...

I have the same problem, having moved in a modern appartment where I am not allowed to erect any antenna on the roof. So remain the portable solution. In your case, for reception, why not to test an active magnetic loop antenna. They cover all the spectrum in continue see e.g. http://www.astrosurf.org/lombry/qsl-ala1530.htm As you are licensed I think, there are also magnetic loops for TX, see e.g. www.wimo.de Only drawback, better to stay over 7m from the antenna due to the magnetic field generated. If you can do that, it's fine. Its performances are not better than a dipole but its is somewhat directive. That helps. Hope this helps. 73 Thierry, ON4SKY http://www.astrosurf.org/lombry |

thanks a million
sounds good going to see if I can build that magnetic loop myself, rather than buying something many thanks On Tue, 19 Jul 2005 11:59:45 +0200, "Thierry" - wrote: "squeege boy" wrote in message .. .

Have you checked MFJ products for antennas that would suit your needs? http://www.mfjenterprises.com There is the mini whip apartment antenna for 40 - 10M, which will mount right on an outside window sill, MFJ-1622, and there are a number of totally indoor antenna loops you can use, although they are rather pricey, such as MFJ-1788. If you operate QRP at 5 watts, or even up to around 20 watts, none of your neighbors will even know you are on the air. Good luck Ed |

All you need is a length of plastic-insulated wire strung up in the
attic, or unobtrusively tossed out of a window, and a large aligator clip attached to the domestic plunbing system. Plus a simple tuner. Believe me - it really does work very well! Ask any real amateur. And don't get yourself all mixed up about so-called SWR, reflected power and take-off angles. ---- Reg, G4FGQ |

"As you are licensed I think there are also magnetic loops for TX-." I agree. The advantage of a small loop is that it is inductive, so a series variable capacitor is needed to tune it, in place of the lossy coil needed to tune a small whip. Best regards, Richard Harrison, KB5WZI |
