Preparing for the upcoming Arctic DX Summit in Kongsfjord this weekend. A Beverage antenna is probably one of the simplest and cheapest antennas one can build but it does have one-draw back in that you need a lot of space or a very long thin garden. With any such receiver, a high-performance loop antenna may be employed, or in the alternative, one or more outdoor longwire Beverage antennas, Nov 15, 2017 A Big MW Box Loop Antenna that pulls in the DX. Review of K9AY antenna by Bjarne Mjelde. North American version The Active Loop Antenna Model ALA 100M is a medium size aperture antenna designed to provide improved performance compared to traditional active and passive antennas. 55 UTC, the station was already off the air, so it went off much earlier than the 18. The Vertical Loop is a good DX antenna. Recently, I wrote about my WSPR tests of a half lambda DDRR antenna. The EMF antenna has two 35mm film canister looking objects connected to it. The antenna can be used by simply placing the antenna near your radio or connecting it via lead wire to the radio's antenna contact. A truly wonderful MW dx season indeed. This is most evident on 160 and 80 but still helpful on 40 meters. Combining either loop with the Quantum Phaser will permit a single null to be obtained, which is an advantage if you are located near the coast and DX transoceanic MW signals. This is done by winding a coil or loop, generally with tightly-spaced turns over one end of a ferrite rod or bar. If you are into AM/MW/BCB This loop makes a huge difference , especially during the day time when MW isn't so reliable. a. "What's the advantage of the Q-multiplication feature in the QX Loops?" All antennas are Broadband, Wideband Active Loop Antennas; the result of continual research and ongoing improvement over several decades. Take a closer look at the ferrite bar antenna. from my Kiwa MW Loop and I have NEVER seen resuls from users of the Quantim Loop to come anyhwere near it. The antenna can be for all LF, MW and HF professional monitoring and short wave listening. Medium wave DX: excellent signal from WBBR New York 1130 KHz despite adjacent QRM Find this Pin and more on DXing by Clint Gouveia . I ran the loop antenna to the aux receiver antenna input on my TS-590. by Graham Maynard. After a fairly good result with my small MW Box Loop antenna for Medium Wave and Shortwave I wanted a better version with more gain. Medium wave (MW) is the part of the medium frequency (MF) radio band used mainly for AM radio broadcasting. Well, this is what can be labelled as raw gain, but net gain, taking mismatch losses into account, is something else. The best compact AM antenna in the world - ever! This is a type of antenna known as a box loop that is very useful for AM broadcast DXing. Where the loop really scores is in the MW band, where it works best and signals that are S9 on the loop quite often are inaudible on my other antennas. Ydun's Medium Wave Info - News, reports, and loggings from the long and medium wave bands. br/Antenna_Loop_Air_Core_MW. MW reception is often plauged by man made interference these days. Should you have any doubts, a fixed wire loop, pointed towards your desired DX, is the easiest of all to build. David was best known in TVDX/ FM Band 2 dx circles for having received the first known TADX on FM Band 2!! KEN'S MW DXING IN SW SCOTLAND: I have been dxing since 1977, and after discovering CJYQ 930, my first MW Trans Atlantic station in November 1978, I became very enthusiastic for mw dxing, a wonderful part of the DX hobby. An active loop antenna is a good choice for medium wave and shortwave Sensitive and quiet enough to get those very faint DX signals from the Loop for MW using Litz Wire. Here’s a clip of 1120 KMOX from St. com in 1 categories. Loop antennas, which are commonly used on medium wave (AM), will also work very well on 2MHz. In-house setup is challenging as well, with four DX-ers wanting continous access to four beverage antennas. Medium wave signals have the property of following the curvature of the earth (the groundwave) at all times, and also refracting off the ionosphere at night (). Whether you’re a ham, MW or SW DXer, there are times when a receive antenna will be very handy. In the first paragraph, I did indicate that this antenna is to be for RECEIVE ONLY. Possibly there is a commercial product here and I should be sending Portable, connected to radio without antenna jack, new never used Description Ÿ DEGEN 31MS is an active room magnetic antenna for MW&SW reception. AM Radio Loop Antenna - KA200 The Kaito AN200 AM Antenna is a beautifully designed loop antenna for enhanced AM or Medium Wave reception. Immediately after the station ID I rotated the loop to the south. MW DX, short for mediumwave DXing, is the hobby of receiving the reception of distant mediumwave (known as AM in North America) radio stations.

Guy Atkins has compared RF PRO-1A, a new antenna from Pixel Technologies, to Wellbrook Communications' ALA1530 active loop antenna, which has been around for years. This manual is a compilation of numerous articles on the subject of design and theory of the loop antenna that have appeared through the years in DX News. If the resulting antenna leads aren’t long enough, extend them using the pieces of wire you cut off in step 4, all twisted so they have approximately 2 turns per inch. I'm listening to my Grundig Satelitt 800 Millennium Edition radio connected to my nearby DIY AM Loop Antenna from my boiler room in my basement located in Yonkers, New York. 00 UTC quoted in your Medium Wave News. Transmitting Antenna!- UGH! More noise- Vertical or Inverted L Omnidirectional- Loud W5’s ,6’s & 7’s Will have to attenuate signals on receiver- My normal mode of MW DX'ing operation with a portable radio is to use my two loops, a 9" Terk "AM Advantage" and an active LOOP (TG34, like a Kaito KA33).

Degen TG39 Passive AM Loop As a lover of various add-on active and passive MW antennas I was interested in testing the Degen TG39 from the moment I saw a picture of it. 5 kHz, using channels spaced every 9 kHz, and in North America an extended MW broadcast band ranges from 525 kHz to 1705 kHz, using 10 kHz spaced channels. The SuperLoop is a super-sized terminated corner-fed broadband loop, a variant of the Flag and Pennant antennas, the concept introduced in the August edition of With any such receiver, a high-performance loop antenna may be employed, or in the alternative, one or more outdoor longwire Beverage antennas , sometimes many hundreds of meters long. The antenna is a combination of a magnetic loop and a sense antenna for the E-field. Click Go. It can accept two antennas High-Z & Low-Z. The concept of the "Hula Loop" came after many years of building medium wave loops of varying size, shape and performance. The canister on the far end is actually an excellent "tuned ferrite rod" designed for MW (medium wave) and really helps any receiver without a built in MW antenna rod. As far as I know, most of the previous work with K9AYs, etc, has been optimized for the 160 meter radio amateur band. Can anyone point me to a good set of plans on the net. The G4ILO Wonder Loop is an inexpensive, easy to make magnetic loop antenna that covers five HF bands, 40m through 15m. Presently I have 3 compact medium wave DX loop antennas which I use for DX'ing purposes - the Radio Shack medium wave loop, the Terk AM Advantage and the Tecsun AN-100. Operation and performance are all about the same and from the photos you can see that the concepts basically t software to optimize various large loop antennas for MW DX use. 5 kHzPassive, fully adjustable indoor antenna for the AM broadcast band (530-1710 kHz) - the grinding AN200 is a passive, fully adjustable indoor antenna for the AM A New Homebrew Magnetic Receive Loop at VE1ZAC .
