Speaking about the previous units, the 4kw gives a much cleaner, finer, more detailed image than the 2kw. Things which the 2kw would only find for a portion of the time become solid with no problem.
You can sit it on the top of your A frame provided it's tall enough. It's not a good idea to scan your brain with 4kwatts of microwave energy. You may need a wedge to set the mounting angle correctly.
