I am using a ground mounted Hustler 5-BTV with a DX Engineering Current Choke. It seems to be performing very well, in spite of terrible band conditions. Right now there are only six short radials being used. Space is rather limited, and radial lengths would be mixed from only a few feet to twenty or thirty feet. Do radials improve received signals, transmitted signals, or both? I can hear DX stations much better than they can hear me (I'm only running ~100 watts).
