Very good 1.01 SWR on the HAM 149 band but 2.65 on the 440. Talking around 35 miles on simplex.

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.

Very impressive that it covers 2 meters, 70cm and GMRS frequencies. Works better than it should stuck on with a magnet mount on the rear bumper of my jeep.

Amazing antenna, reception is great and transmission is great. One of the best ham radio antenna in the market for 2 m and 70 cm.
