This reminds me of the fine signals 3Y0X was producing on 160 back in February 2006. They were using a 3 el horisontal beam 4 ft above the ice...

Bear in mind that MY Dipoles have always been pretty low, around 50ft. Also that the British stations I have done proper comparisons with all have decent verticals, typically at least 70ft high and over 40 quarter wave radials. (you would recognise their callsigns) I personally suspect that having a poor ground under such a low dipole would cause it to have more low angle radiation than EZNEC predicts (ie the antenna "thinks" it's higher). This seems to be born out by the fact that people who have a Dipole that is over a radial system (for their vertical) DOESN'T seem to work so well for DX as mine does. So although having my own Vertical AND a Dipole to compare would be great, I would only consider it if I could get the Dipole a long way away from the radials. (in practice I could never get a proper set of radials out, nor could I go high enough - I live in a very ordinary street with a normal-sized garden, so one leg of my Dipole goes across the street!) I do at least now have a Receiving Loop in my Loft, which is vertically polarised. (and has a pre-amp, set to make local signals the same strength as my Tx antenna). It's very interesting to note the difference on signals switching between the two. Occasionally, there can be 10dB difference . . . but MOST of the time, DX signals are exactly the same strength on both (which supports my 2 theories) However, based on my signal reports from DX stations, it does seem that my low Dipoles have always worked much better than most of you guys in NA that have tried them . . . so I wonder why that is? Is it down to these Geomagnetic lines? _________________ Searchable Archives: http://www.contesting.com/_topband - Topband Reflector _________________ Searchable Archives: http://www.contesting.com/_topband - Topband Reflector
