The 200W version has a low range that can measure power down to 0.1 watt. The minimum reading on the 2000W version is 1 watt. On 5 Jan 2015 10:12, David Ferrington, M0XDF wrote: I would have thought there is some difference, otherwise why go to the trouble of making two different models? -73

Dan, With the 2000 watt coupler, you can still select either the 20 watt, 200 watt, or 2000 watt scales. I doubt there would be any difference in resolution by using the 2000 watt coupler with the W2 set for the 200 watt scale. The manual specifies accuracy of +/- 0.5 dB typical for both se

100 Watt station with 2 antenna. Need a second coupler of the W2. First one is 200 watt, and thinking of adding a 2000 watt coupler for the second (future proofing for possible linear). But, wondering if there is some accuracy/performance trade-off using a 2000 watt coupler on a 100 watt stat
