How bad would the interaction be between a raised vertical (BigIR III w/80 m coil) and a 45-50 ft tower that is 20ish feet away. Vertical will be apx 10' above ground with resonant radials on 40 and 80 (2 each)...I know ground mount with 60+ radials is far better but this is all I can do for now. Will I be wasting my time? Suggestions? Thanks, Pete WA2ODO
