Comet SBB-5NMO 2M/70cm Dual Band Ham Radio Mobile Antenna for Car, Truck & RV - High Performance VHF/UHF Antenna for Amateur Radio Communication

Excellent gain on VHF and UHF. Ad claims 1.5 swr. However, the antenna seems to be maximized at the low end of 2 meters, and around 458 mhz on the 70cm side. While I would rather see it optimized at the high-transmit repeater input frequencies, the difference between 1.5 and .5 really doesn't hurt much, and being a dual-bander at the length of it (38 inches), there will, of necessity, be compromises. Antenna folds over for driving into the garage or under low tree coverage. I'm going to use it as it is -- fooling around with it could screw the whole thing up. Put it smack in the middle of the car roof for best SWR and radiation pattern.
