 But if its a vertical positioned  dipole it does not need a counter poise or radials as its a dipole. A vertical dipole has a pattern and low take off angle like a true vertical but the feed line must come away from the center at a 90 degree angle for best performance for several feet. 

Also a ground plane is a great antenna for low angle of radiation. To be a true ground plane the radios should be off the ground at least 1/8th wave but if you can't do that any height above ground will work. The best thing is that 3 or 4 above ground radials 1/4 or 1/8 wave length long will work as good as 100 buried radials. This antenna is simple to make just hange some wire, its easy for bands 40 meters and up and if you have some really nice trees 80 and maybe 160..

Certainly those that you and N0AX tested 2o years ago. Like any 
vertical, their performance will depend on soil conductivity, and they 
will work a bit better if roof mounted.
