Range is a terrible way to judge an antenna. No antenna can guarantee you any particular range, it depends entirely on propagation (among other things). SWR is also a terrible way to tell how well an antenna is tuned. SWR only deals with impedance matching, has nothing to do with resonance (the other half of tuning any antenna). A dummy load has a -very- nice SWR, but makes for a terrible antenna. A dummy load is also resonant, but still a terrible antenna. There's more to it than just those two thingys alone. Probably the biggest 'thingy' is the antenna's length since that determines it's radiation pattern, it's 'foot print'. If that radiation pattern doesn't put a signal where you want it, then it's not very beneficial to you, even if it happens to be a very convenient size that 'looks' nice...
