- If this is the one with UHF connectors on it, (or type N) it is rated for 1 KW. Stuart K5KVH _______________________________________________ TenTec mailing list TenTec@contesting.com http://lists.con

- For what it's worth (OT), I expect the power ratings (and frequency response, too) are based on 1:1 VSWR / 50 ohms. It would be useful to know what they can do with say 2:1 VSWR. I.e., you want some

- Phil, Not nit-picking here, but why would the specs leave out insertion loss ? One of the most important specs for anything after your final RF output device. Also interesting that very few manufactu

- Dunno Tom... Got that info from a B&W Catalog I found in a drawer. Remember too, those power ratings are for AM. I guess with 80% efficient Class C, you can afford a little insertion loss. __________

- Well, if they aren't terminated in the design impedance, they aren't going to be much of a low pass filter anyway. 73 K4DPK -- Original Message -- From: "Martin Ewing" <m.ewing@snet.net> To: <tentec@
