    Yes it was trivial to jam.

    On the occasions that it did not respond to jamming it was because nobody was watching the return display!

    If you want to understand more read about the "radar range equation"

    Also read about "a scope"

    Then read about the "radar jamming equation"

    Take your best guess as to the "radar cross section" of a ballistic missile in its coast (mid course) phase

    Understand that the rocket contrails during the boost phase would be indistinguishable from the ground clutter returned to the radar operator.

    Consider sunlight is around 1000 watts per square meter....

    Do you just string random words together to make impressive sounding reports in your professional career?

    And waveguide , do you see any @$%€#! waveguide in the picture?

    Sure do.

    Not all waveguide is a hollow tube. Coax, for example, is a waveguide. Dont get hung up on 'zero TEM' in defining waveguide.

    Transmission of waves and boundary conditions define 'waveguide'. I understand the engineering convention of 'waveguide'.

    If you mean is there zero TEM 'waveguide'....I imagine it was mostly stripped from the Duga and put rubles in someone's pocket.

    Now be nice and stop trying to 'stump the professor'.

    Chip & Rege - knock off the endless barbs. Debate is fine - but all the personal barbs at each other are getting near the line and starting to poison the thread.

    It's otherwise an interesting discussion that is on the way to being locked.

    Connect a KW amp output directly to another transceiver.

    What happens?

    You can do a lot of damage with 1000 watts...

    Video was UN-inspiring, if they knew the significance of the equipment they were flying their drones around then there could of been some good shots of the feeders, dipoles and other gear. Reasonable effort but typical of dumb down tech users. Sorry for the alternative response but they missed a perfect opportunity to gain knowledge but instead seeked personal thrills over knowledge. Very typical of what the education system produces.
