I use the MFJ "Ham Stick" and they work really well. I carry seven or eight antennas with me and have quick connect mounts on the bottom. From 80 meters to 10 meters and have no problems with them at all. Once they are tuned, my auto tuner in my Icom 746 makes only minor adjustments for flat SWR. The 80 meter has a very large amount of wire wrapped around the core and the six meter has very little. The lower the frequency the more wire they pack on. All of these antennas end up being 7'11" long with the stinger installed. There is some variance in total length but not much.
