Mike, In less I am missing something, I don't understand why you should have an S W R of 30:1 through a length of coax. This would suggest there is something wrong with the coax. What type of coax are you using and how long is it? If you were feeding a one half wave dipole which is suppose to be approximately 50 ohms at the feed point, using this coax would have the same 30:1 S W R as you had with the 50 ohm dummy load. Just because you can tune out the 30:1 S W R, doesn't mean there is an efficient transfer of R F from the coax to the antenna at the feed point. Unless there is something wrong with your dummy load, it looks like you found the problem, replace the coax!
