Just out of idle curiosity, what kind of antenna system do you use? Just an idle answer... I have a 130 foot long, 25-30 foot high, bent dipole between two trees, fed with ladder line, used on 80-10 (including WARC bands) with a Johnson KW Matchbox balanced tuner. On 160 meters, I reconfigure the antenna to what is essentially a top loaded vertical, using a T-match tuner. Obviously not as good as a tower and beam, but I work lots o' DX with it, for example the VK0IR (Heard Island) dx'pedition and North Korea. (If you are not a ham, trust me, these are nice catches). Needless to say, it also works nicely for SWL'ing with my vintage receivers. A tower would be nice, but not worth the hassle of dealing with the (overly) strict city and subdivision restrictions.

And particularly for MW Dx. I'm tempted to do it here. Well, it won't hurt to try it... Your buddy says it is a quiet antenna. Compared to what? It is commonly acknowledged that noise is more vertically polarized and thus a vertical antenna is a bit noisier than a horizontal antenna like a dipole. I really don't think the dipole I described is any quieter than any other dipole AFAIK. The reason I used the antenna was mostly because of its benefits when transmitting. With the tuner and the ladder line feed, it will operate on many bands with relatively low line loss. For SWL'ing, I'm not sure if it would have any particular benefit. Which vintage receivers are you using?
