I added an impedance matching ‘hairpin’, a 2-inch, 8 turn coil, made with #14 wire, which is connected across the coax connections. Adjust by compressing the coil turns tighter together or spreading them out. Then you can add or remove turns of the coil to match impedance. Results

WebA hairpin match is a hairpin shaped "stub inductor", generally balanced, but it could be unbalanced. It is called a hairpin because it looks like a hairpin, just like a "bobby pin" spread out a little. A shunt matching component can be used, either an inductor or capacitor, but this is typically called shunt matching because it is a shunt component
