Any real reason, benefits, problems, thoughts or comments about running an external SWR/PWR meter inline between the antenna feedline and the radio(s), especially if the radio(s) have their own built in SWR/PWR meter? (This conversation came up at a recent meeting.) Some are all for it, others just the opposite, so I am gathering other's opinions. What are the pros and cons? I have noticed that if I do this, my readings are drastically different. For instance, it can be 1.0:1 on the analyzer, but show 1.4:1 on the external meter and worse, 1.9:1 on the radio's built-in SWR meter. (Putting the feedline directly to the radio will result in the same SWR reading on the radio as I got on the analyzer, 1.0:1.) The jumper coax I am using is a Times Microwave LMR 400 and has tested perfect. I know that there will be some loss, but this seems extreme to me. It could be that I have a "less-than-perfect" external meter. It is a MFJ-849, but it shouldn't be causing this much of an issue I would think.
