I asked around on the SteppIr Yahoo group. Some hams told that SteppIr had used Mission boots for a short while but the are back to Femco boots which are better. Let me have the Mission boots… Today I wrote an e-mail to Vine antennas where I bought my antenna and Ron told me he would replace all the 10 broken boots for free. I only have to pay shipping. That’s what I call great service!
