VSWR Alert circuit?

what is your request, i fact it is not easy to realize the VSWR alarm accurately!
so you should provide more information for your request!

If you have 7 dB attenuate (including filter and cable loss) between amplifier and antenna, is impossible to see if antenna end is open, shorted or connected correctly if approved VSWR level is setting 14 dB or lower - and is hard to calculate more than 20 dB VSWR on coax cable itself and antenna itself not calculate better than 14 dB VSWR...


Say same as springf2000, is very difficult to make _working_ and _accurat_ VSWR alarm more than supervision if first connector tighten and short cable length after amplifier and VSWR-measure bridge - not more...
