prevent the vector arrow from centering over the letter + subscript

Question

I want to typeset a vector with an arrow over the top that has a long subscript. My approach makes the vector arrow center over the letter including its subscripts, but I want the arrow to be centered over the letter only instead. Does anyone have an idea how to achieve this? I guess it will be kind of easy for you folks, but I couldn't find an answer by googling.

My code:

\documentclass{article}
\usepackage{amsmath}

\begin{document}

\(\Vec{H_{\mathrm{n,1}}}\)

\end{document}

my output:

I would like the vector arrow to be centered over the "H" instead of the whole thing.

Personally, using a vector notation with an upward slanting arrow positioned toward the center is not at all appealing to me. There are so many ways to write a vector in LaTeX. Here is a suggestion using esvect package with the c option. But you can choose any of the options you like from the link that I have added.

\documentclass[a4paper,12pt]{article}
\usepackage{amsmath,amssymb}
\usepackage[c]{esvect}

\begin{document}
\(\vv{H}_{n,1}\)

\end{document}

This is with the option f similar to tikz-cd:

\documentclass[a4paper,12pt]{article}
\usepackage{amsmath,amssymb}
\usepackage[f]{esvect}%%%%%%%%%%%%%%%% option f. 

\begin{document}
\(\vv{H}_{n,1}\)

\end{document}
