Hey OT
:

Most so called VSWR meters will give you a reading but is it a true
reading? Not likely, by the time the reflected wave comes back down
the cable it has lost some voltage because of cable losses.

A true method would be to measure the voltage at the antenna,
telemeterize the voltage reading and send it back to the VSWR meter to
compare to the output voltage of the tx. And use a dual cross meter
so the ratio is calculated by the meter scale with no adjustment
needed. Except to calibrate it just once.

For my RF project, I want to measure vswr readings, in order to
that I was planning to construct a VSWR meter. The concept of VSWR is to
calculate the ratio of Voltage transmitted to the Voltage reflected. So
my basic question is,

1. What sensor/instrument is used to measure the voltages from the coax
cable(in my case)?

Please some one help me with some ideas
