    $\begingroup$ Hi, can you tell us: What is the antenna for? What frequency and application? How many turns? Will it stay connected to the scope, or be connected to something else? $\endgroup$ Commented Dec 20, 2020 at 16:32

    $\begingroup$ What have you already read about feeding technique and what don't you understand? $\endgroup$ Commented Dec 20, 2020 at 16:58

    $\begingroup$ I like this photo! 1. Can we see a close-up of the spark gap assembly on the left? I am wondering if the either the spark gap or the loop needs to be turned 90° and/or moved a little further away (thoughts, anyone?). 2. Why do you think it needs to be shielded? I don't believe that it does. 3. You can cover your antenna with plastic tape, but it will not provide any shielding effect whatsoever. $\endgroup$ Commented Dec 20, 2020 at 19:51

    $\begingroup$ 4. Is the black vertical cylinder to the left your impulse generator/power supply? It may contain a transformer that is coupling to your loop more than the spark gap is. If so, it may need to be shielded by covering it with metal foil. $\endgroup$ Commented Dec 20, 2020 at 20:01
