You'll either need 2 antennas like stated by magnuman, or get a decently braodbanded antenna and use an external antenna tuner. The sirio Vector 4000 is a good vertical antenna with a 2mhz or so bandwidth with a 2:1 VSWR Max. I've one up at 26ft. approx. to the base of the antenna and it will tune from 26. MHz to 28. MHz. Now if you had a decent antenna tuner, say something like an LDG Z-100P. Cost is about $140, but you can use most any regular 10-11 meter antenna and it will tune to wherever you want to go with the optima MK3. This is probably the easiest solution. You can get manual antenna tuners for less I'm sure, but stay away fo from MFJ if possible. Just not heard too many good things about them as a whole, other than their analyzer's being okay. The analyzer I use seems to work fine for what I use it for. But a tuner is a bit different. I've heard good things about the LDG tuners and they seem to get good reviews as well. Also check EBay for maybe a used one. For the money, at just over $130 I'd just spring for a new one and the best antenna setup you can afford or can put up. The A99 is an okay antenna, if you're going to go that route get the IMAX 2000 instead. With the IMAX 2000 and an external antenna tuner, whether it be manual or auto type, you should have no issues getting 10-12 meters with a good vswr. It may come at a cost of efficiency, but it will keep the radio happy and you won't be too far off with VSWR anyway to kill your efficiency that much I wouldn't think. The IMAX 2000 should come preset from factory for 27mhz. Just leave it be as is if you have good readings from the get go and use the tuner to get to the other places you want to go. JMHO as to what to get. Hope some of it might help. And remember this, your antenna system is the most important thing besides having a radio itself. Without a good antenna setup you might as well just be throwing money away. Get good coax like Belden, times microwave, Andrew, Commscope, Judd wire, Davis RF, and so on. LMR400 or LMR240. I know it's overkill but it's worth it IMO. You can get rg8x and most likely it will work fine depending on the length of the run. Keep it to under 100ft and you'll be fine with some good rg8x or lmr240 or lmr400. I use Andrew's version of LMR400. Good coax. Also use 123 wireless lmr240 and it seems to be a solid coax. Great shielding and has UV protection, as does the Andrew LMR400 type coax I use in conjunction with good amphenol connectors. Again, this is JMHO, some may disagree, but I would spend as much time, effort, and purchase quality coax and connectors as well as the best antenna I could afford.
