I've read several responses indicating that verticals are more noise-prone than dipoles, cf zepps, etc. I live on an average city lot with power lines at the back, and my experience has been a little different. I've used a Butternut HF-2V with 16 radials for many years. I've also experimented with a variety of wire antennas, including center fed zepps, dipoles, vertical dipoles fed with ladder line, verticals with elevated radials, verticals with loaded elevated radials (as in Moxon), and consistently the ground mounted vertical monopole is quieter (and provides at least the same signal strength). I've also tried a simple monopole for 30 meters (made from HF-2V parts) mounted on the same ground system, and found it to be quieter than any of the wire antennas on 30, either vertical or horizontal. I believe the ground system is key to the whole thing.....the ground mounted vertical is simply quieter than elevated ones. If you can install a decent set of radials (quite easy to do: mow the grass, stake the wires out, and let Mother Nature hide them for you; at least it works in Ohio), I think a vertical is worth considering. I've done extensive EZNEC modelling of all these antennas, and while interesting and fun, the noise issue is hard to predict and can be one of the more important considerations.
