Dear all
I have some long lines of LMR600 of approx ~120ft for 800mhz and 150mhz monitoring,, want to be able to caclualte DB loss for antenna to the rig,
rule of thumb we can say X db of loss per ft of ZZZ type of cable and add so much for each connector of ZZZ type etc, however this is still a guess,,
I want to *know* what the loss really is., what kind equipment would I need to really test or measure for this,
and what is the basic concept behind this? xmit so much power down the line and measure it at the other end?
THanks and sorry for the dumb question
