I cannot imagine anyone being so absent- minded as to connect any test gear (other than dummy load or a power meter/inline swr meter etc) to ANY transmitter or generator of rf. Even leaving the extended telescopic attached to the Tinysa could damage it in the viscinity of a powerful PA especially if mismatched/poor grounding/leaky dummy load. ?You might be quite surprised how much RF you are exposing yourself to when transmitting - another use for the Tinysa.
I have used small 1,2 or 3 turn loops (insulated) about 1” diameter attached to a length of 316 coax very useful, also for sniffing around equipment and chaising sources of interference. The insulation is necessary in case components are touched by the loop. You can see what needs screening then (also useful as input to a scope sometimes).
