80-10 meters. Mostly gonna use it portable with my Xiegu G90. Figured I take it with me while traveling. Haven't used it yet, except to test on 3.600 MHz. I haven't received the tap point chart yet. In the fully extended position and no taps, it's supposed to be resonate on 3.600 MHz, which it is. I can't recall the watt rating, but I can screw this down on my screwdriver mount on my Jeep, use it while traveling, then unscrew it and use portable. Since my G90 has a tuner, I don't need to make a choke, although, I likely will in the winter days. For now, I'm feeding it with a 25' section of RG-174. Same size as the counterpoise and packs neatly.
