I fully agree with that statement. If it is an old RADOME, chances are high, that it will only fit to the original radar set. This is because the so-called anlog radar sets did all the signal processing in the PPI unit. (They still do so)
If it is a so-called digital radar scanner (antenna) then there is a chance to fit it to some other than the original set, because all the signal processing is done in the scanner unit.
