    Possibly but I suspect not.  Depends on the noise you are experiencing.  Tell us more about that:  All bands?  With or without antenna?  Does it vary with time of day?  Is your station grounded?  Are all the devices tied together? What type of power supply are you using?  etc.

    The easiest was to tell is to disconnect the antenna. If the noise is still there it's coming in through the power (unlikely). If it goes away then it's coming in the antenna (good luck!)

    Yes. In my experience, switching power supplies radiate noise far more than they superimpose it on the output DC. Radiated noise comes in the antenna.

    When they are noisy on the output DC an isobar still won't help. You would need to run the DC output line through a toroid on its way to the radio.

    I recommend that you not over-think this. Get the radio and see what your environment gives you then go from there.

    I use Tripplite line isolators between the AC line and my equipment.  I find that they reduce electrical line noise, as well as holding up the AC line voltage and protecting against surges.  I have one that just services my amp and another that does the remaining shack items.

    I do the same thing and also use a Tripplie Line Conditioner to ensure the AC feeding my devices after the UPS is clean.

    Adding the Isobar won’t make it worse, for sure. I recommend it as part of an overall noise mitigation plan. Grounding, shielding, ferrites, quality cables, and careful placement really help.

    I have used isobar power strips for years. Line noise reduction is minimal, but RF isolation is great and isolates between outlets . Very good surge suppression. Received a direct lightning strike on the power line outside my house, all equipment on the isobar was ok. One kitchen appliance was killed, no surge protection. Proof is in the pudding...... Pat
