My living situation is far worse (for SWL that is) compared to back then when living ina quiet suburb. Living in the city centre now with a supermarket with huge fans on their roof for cooling the freezers and such, and ofcourse all the equipment from our neighbours. So I've been reading the forums, sites and newsgroups on my equipment and found that generally the receiver is well received (*g*), and the antenna is not! Back then though I've been able to receive quite a bunch of QSL cards from stations I picked up in the tropical bands. Had lots and lotsof night of fun! But, to improve my antenna situation I've been looking around to see for alternatives. Active antenna's are out of the question for me. Frick, the quality ones seem to start at 200Euro. As a soon to be daddy and other expenses coming up I can't afford those... I've little room for a reasonable 'random wire' either. After some looking around I decided to give the EMF antenna a try from RF-Systems in the Netherlands (where I come from as well, accidentally). After a few days of trying different configurations (indoors, out on the balcony, horizontal, vertical, north-south, west-east and all inbetween, 30 degree sloped, earthing to the earthwire in the powerbox of the appartment, etc) and comparing it to my Sony AN-1, I can savely say, at best the EMF antenna produces equally to the Sony An-1, but has never exceeded it. It seems to pickup far more noise and interference then the AN-1 does. So the EMF is up for grabs for anyone here who makes a good offer for it! I also have to add, I did quite some browsing and reading on the EMF before I ordered it, and the general tendency was it is an OK antenna. I guess, in my situation the AN-1 isnt such a bad antenna after all, or the EMF is for my situation a really bad antenna! This week I am going to try and build a magnetic loop. At first I saw many daunting schematics which are too technical for me with my left hands, but I found this page (http://www.kr1st.com/swlloop.htm) with a *very* simple version that according to the writer is so simple as it is for receiving only. Apparently, the transmitting ones need to be far more technical. Does anyone has any tips regarding building any of these? My particular interest is the 60meter band. And, anyone any comments on my EMF/AN-1 comparison? I think I pretty much tried all configurations, and in reality there isnt much to do with the EMF, its all prebuild. But I'm open for suggestions! Small active loop antennas are pricey but are most likely the best in town choice. To get an idea how this type of antenna will work in your location you could build a passive loop at small cost using just coax cable. -- Telamon Ventura, California |
