The Comet CMX2300 is a true twin SWR/power meter. The left side covers 1.8 to 200 MHz with up to 3000 watts (30/300/3000). The right side covers 140 to 525 MHz. with up to 200 watts (20/50/200). FWD, REF and SWR readings are displayed simultaneously on each meter. And both meters can even be used simultaneously. The meters are very dramatically back lit.
