What about using a 2m/440 mobile antenna that doesn't require a ground plane, such as a commercially made end-fed half-wave? I know Diamond, at least, makes one. Howard N7SO _________________________

Thanks Jim. In my case I'm 1000 feet from the nearest neighbors, so my ladder-line fed dipole isn't an issue in that regard. Many years ago, however, I lived in a townhome where I installed a 50' dip
