Preparing the antenna for IH9/IZ2LSC

Yesterday I prepared the vertical dipole for 17 m. that I want to use from Pantelleria AF-018.
The total length of the dipole is 790 cm and it's mounted on a fishing rod. I used a balun 1:1 from Siegfried DK9FN.
I tested it in my backyard near concrete wall and metallic objects, so it' not an optimal location but I want to find out the rough measure to facilitate the installation on the island.
This is the SWR curve:



And These are R Z and X:


Not so bad for now.
