At the advice of many, I simply removed the 9:1 UNUN (Palomar Engineering) and made a "direct" connection to the rain gutter via a sheet metal screw.
Then ran one radial along the ground (I will try more radials later).
Much to my surprise, it now loads better on the 10/15/20 meter bands.
I will try it on the air today (QRP power only) to avoid setting off any fire alarms here (TU for that advice).
I realise that the information from the Nano VNA in my shack has limited value - TU.
Coax is 50 ft RG8X (decent quality) and a couple of "isolators" (RF chokes) in the shack.
