2slow2matter... If you check your plane out to failure, I think you will discover you did reduce your range. Your range check was only out to 75 feet without failure. How can you say tyour routing didn't effect the range until you test to failure? Probably not worth the effort to really check if you have been flying with out problems; however, you must test to failure to see if you effected range. For example, if your normal range check fails at 200 feet, but you only test to 100 feet after a antenna change, it is possible you reduced your range by 50%, but you would never know because you only tested to 100 feet. Cheers.
