I have my Cushcraft A3S w/ A743 40m add on kit at 10' on a pole after refurbishing it. I've tuned it for the part of band I want (CW & RTTY) with my MFJ-259. My question is, how much will the tuning (SWR/reactance) change when I get it back up at 70 feet? Will it be about the same or higher? -- 73 Harvey, KM4JA Ozark, AL
