We really need more info to give you a good answer. For now I will assume that you are talking about a 10,15,20 meter antenna. Also l will assume you want some good low angle radiation for Stateside and DX. If this is correct and 20 meters is important, try hard to get it up as high as possible. It will work at 25 or 30 feet, but much better if you can get it up say 40 feet or more. Lower heights required for 10 and 15 meters. I mostly agree with WB6BTU since re: the radiation pattern of a dipole. However I have found in my experiments on 30 meters a dipole does have very significant nulls DIRECTLY off the ends for both the path (3000 miles) to either WWV or WWVH from my Alaska QTH, and local tests with transmitters less than 5 miles away on 10 MHz. Now the pattern, both the model and experimental, agree with each other VERY closely. The pattern roughly broadside to a dipole, shortened or full size, is very broad, so over much of the 360 degrees, with atmospheric fades, etc. probably no need to rotate. However, off the ends the nulls, both the models and measured, averaged at least 15 dB deep if nearly directly off the ends. Sorry I did these tests decades ago, so lets say over something like + or - 5 degrees from directly off the ends, and occasionally if I carefully adjusted the rotator the nulls were MANY S units deep. Often, I have good propagation to both WWV (great circle E), and WWVH (great circle S) from my location. Just turning my dipole 90 degrees often lets me clearly hear only WWV when aimed E, and only WWVH when aimed S. If your dipole is a wire and horizontal, and at the same height as the rotary dipole, then not much difference in many directions, BUT if the wire dipole is an inverted V or even something like 10 feet lower, than the rotary one may be worth the cost and effort. When I work a whole region of the world, I do not bother adjusting the 30 or 40 meter dipole for say different countries in Europe, or most of the lower 48 states, but for sure it is down a few S units directly off the ends. I do not have problems with trap antennas, in many situations the loss is small and the versatility is worth it as long as the traps are designed for your power and you can live with reduced bandwidth.
