I am a relative newbie to the world of SW.
I've just taken possession of a second-hand Kenwood R5000 comms receiver. It looks like a very nice piece of kit. It's not really practical for me to rig an outside antenna system at the moment, but I have heard that you can get SW antennas designed for indoor use. Can anyone recommend any? I am in the UK. And if anyone has any thoughts on the R5000, feel free. |

I used one for some time in an antenna restricted area and had very good results with both DATONG AD-370 and DRESSLER ARA-30 active antennas mounted in the attic. There are some terrible junk gadgets sold as active antennas but these have been so good to me that they are now mounted outdoors and are coming up on 20years continuous service. The DATONG is a dipole configuration and DATONG makes some really good stuff but appear to have moved to the professional surveillance field so I don't know if their antennas are still available at a good price. They are a UK company so you might look around. The DRESSLER is a short fireglas whip and a quick check shows DRESSLER active antennas at www.hamradio.co.uk and several other sites; although the ARA-30 is probably not available any more, the ARA-40 and ARA-60 appear to be more modern versions. I have had many years of enjoyment with my R-5000 and those antennas. Good luck Dave |

I then found that the dealer (Martin Lynch) is located quite near to my house, which is very convenient! I phoned him up to see if he had any Dresslers in stock. He does, but interestingly he recommended another antenna which he thought would be better for my purposes - the Miracle Whip. He also stocks them. They seem really good - easy to connect and don't require any power supply. Have you or anyone else had any experience with these? http://www.miracleantenna.com/MiracleWhip.html |

Have you or anyone else had any experience with these? http://www.miracleantenna.com/MiracleWhip.html I think you'd do as well with a piece of wire. You only need a tuned antenna when you are using a transmitter, that requires an impedance-matched load. These antennas would be okay for toting a receiver around with you. I have a broadband rubber-duck antenna on my Yupiteru radio, so I can listen to SWBC while holding the radio. But 10 feet (~ 3 m) of wire works just as well. Spend your money on postage for requesting QSL cards. "PM" |

Have you or anyone else had any experience with these? http://www.miracleantenna.com/MiracleWhip.html The Miracle Whip is designed for use with transmitters, the controls match the antenna to the transmitter output impedance for maximum transmitter power output - for a receiver I doubt you would notice a lot of difference on the HF bands between it and a few feet of wire. By the way - don't try to transmit with a Dressler or similar active antenna, you will cook it! With a very few exceptions active antennas are for receiver only. Dave |

RH,
The Miracle Whip Antenna is a 'nice idea' but you could do better for the money and have greater flexibility in your Antenna Options. MWA= http://www.miracleantenna.com/MiracleWhip.html Vice the Miracle Whip Antenna consider: MFJ-956 {Passive} Pre-Selector -&- Antenna Tuner greatly improves reception from 150 kHz to 30 MHz (especially below 2 MHz). The MFJ-956 has Tuner, Bypass and Ground; Antenna to Receiver positions. Use the MFJ-956 with an InDoor or OutSide Random Wire or Loop Antenna. http://www.mfjenterprises.com/produc...prodid=MFJ-956 MFJ-1045 Receiver Pre-Selector for the Shortwave Bands 1.8 MHz to 54 MHz. This Active Pre-Selector amplifies weak signals and helps to Reject out-of-band signals and images. The MFJ-1045 has variable RF Gain up to 20 dB. Pre-Amplifier has a Dual Gate MOSFET, bipolar transistors for low noise, high gain. The MFJ-1045 External Connections for 2 Antennas, 2 Receivers for both Coax SO-239 Jacks and RCA Phone Jacks. Also has a ON-OFF/By-Pass Switch for 'direct' Antenna to Receiver Hook-Up. Use the MFJ-0145 with an InDoor or OutSide Random Wire or Loop Antenna. http://www.mfjenterprises.com/produc...odid=MFJ-1045C MFJ-1020 InDoor Active Antenna for both the AM/MW Band and the Shortwave Bands. (Covers 300 kHz to 40 MHz in five bands.) Has a built-in 20 inch (50 cm) telescopic antenna. Plus an auxiliary SO-239 Antenna Jack is provided. When using an External Antenna, the MFJ-1020 functions as a Pre-Selector. The MFJ-1020 front controls include: RF Gain, Band Selector, Tune and ON/OFF-By-Pass. The MFJ-1020 also has a wing-nut for a separate Ground Connection on the rear panel. Use the MFJ-1020 with the builtin WhipAntenna or use an InDoor or OutSide Random Wire or Loop Antenna. http://www.mfjenterprises.com/produc...odid=MFJ-1020C .. ..

One question to Dave - I realise this will may seem a silly question but why do you use two aerials? Do they have different characteristics, or maybe you use them for different frequency ranges? Radiohead. I currently have 15 aerials/antennas - 5 in the attic, two on the chimney, three on the tower and rest sort of spread-around the yard. I use them for different frequency ranges and radiation angles - short range HF is best at high angles whereas long range HF is best at low angles of radiation. 7 are transceive and the others receive only. Actually I have 16 since one feedline also has a relay box to select a short whip or a horizontal wire. And mine are all pretty simple ones, none-of the really complex high gain stuff that people with lots of space can install. Antennas are fun and challenging, easy and cheap to make, arguably the most important single contributer to a communications link. Improvement to your antenna system will almost always far outperform any improvement to the receiver that you can perform for the same amount of money and effort. Dave |

RH,
About the use of Two (2) InDoor Antennas with the Kenwood R-5000. KENWOOD-R-5000= http://groups.yahoo.com/group/kenwood-r5000/ Most people have an 'interested' in AM/MW Band and/or the Shortwave Bands. When you are limited to using an Indoor Antenna then the Physical Size Limits of an Indoor Antenna can make it harder to have one Antenna that does it all for the Kenwood R-5000. For Indoor Antennas, consider using one Antenna for the Shortwave Bands and another Antenna for the AM/MW Band. Loop Antennas generally are lower noise and work well as InDoor Antennas. Two Commercial (Ready Made) Loop Antennas that many people like are the Sony AN-LP1 for the Shortwave Bands and the C.Crane {Justice} Antenna for the AM/MW Band. http://groups.yahoo.com/group/Shortw...na/message/849 Both of these Antennas will work with the Kenwood R-5000. THE HOOK-UP - With the Kenwood R-5000 you could have the Sony AN-LP1 connected to the ANT#1 SO-239 Jack and the CCrane connected to the ANT#2 Terminals. THE "DO-IT-YOURSELF" ALTERNATIVE: {Home Made Loop Antennas} READ- The Right Loop Type for the Right Band http://groups.yahoo.com/group/loopantennas/message/1507 * Build a basic Box (16"-24") Loop Antenna for the AM/MW Band to use with the Kenwood R-5000.

For a low cost INDOOR Antenna solution consider using the MFJ-956 Active Antenna with an On-the-Window Antenna. Couple the MFJ-956 (Multi-Use-Active-Antennas) with the a simple Random Wire Antenna that is folded into an On-the-Window Spiral. http://photos.groups.yahoo.com/group...WL-Antenna/lst [Photo Album] "WINDOW" On-the-Window Antennas Usually next to a Window is the best 'location' (Higher Signal Levels with Lower Noise Levels) that can be found for any InDoor Antennas. This is the so called OutSide [In-Doors] Antenna. ABOUT - The Vertical "Spiral" On-the-Window Random Wire Antenna: Use a Thin #28-36 Magnet Wire or #30 Insulated Kynar Wire Wrapping Wire taped directly to the Window with Clear Scotch Tape. Start with the Wire Antenna Element spaced 3" from the Edges of the Window and then use a Space of 1" in between wire element runs. QUESTION - IS AN "ATTIC" ANTENNA POSSIBLE AT YOUR LOCATION. READ - "Snake-in-the-Attic" SWL Antenna http://groups.yahoo.com/group/Shortw...na/message/313 Use a 'direct' "F" Connector to PL-259 Plug to the SO-239 LO-Z (50 Ohm) Jack. RadioShack Catalog # 278-258C This can plug into the Kenwood R-5000 Receiver or into the MFJ-956 Active Antenna / Pre-Selector. .. ..
