Não há problema em páginas ímpares. Somente páginas pares e \newlinecomando adicionar possuem espaço em branco. Então, alguém sabe como consertar isso?

Answer 1

Você tem que usar \\em vez de \newline, junto com \raggedrightou \raggedleft.

Também simplifiquei o código.

\documentclass[a4paper,11pt]{book}
\usepackage[
  left=1.5cm,
  right=1cm,
  top=3cm,
  bottom=1.5cm,
  marginparwidth=5.5cm,
  marginparsep=1cm,
  outer=8cm,
]{geometry}

\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage{lmodern}
\usepackage[svgnames]{xcolor}
\usepackage{amssymb}
\usepackage[fulladjust]{marginnote}
\usepackage{ifoddpage}
\usepackage{showframe}

\newcommand{\printarrow}[2]{%
  \makebox[0pt][#1]{\makebox[\marginparsep]{\color{red}$#2$}}%
}

\newcommand{\arrow}[1]{%
  \checkoddpage 
  \ifoddpage
    \marginnote{%
      \printarrow{r}{\blacktriangleleft}%
      \parbox[t]{\marginparwidth}{\raggedright #1}%
    }%
  \else
    \marginnote{%
      \parbox[t]{\marginparwidth}{\raggedleft #1}%
      \printarrow{l}{\blacktriangleright}%
    }
  \fi 
}

\begin{document}

TEXT\arrow{\textbf{H}igh \textbf{F}requency\\
   \textbf{V}ery \textbf{H}igh \textbf{F}requency \\
   \textbf{U}ltra \textbf{H}igh \textbf{F}requency\\
   \textbf{S}uper \textbf{H}igh \textbf{F}requency}

\newpage 

TEXT\arrow{\textbf{H}igh \textbf{F}requency\\
   \textbf{V}ery \textbf{H}igh \textbf{F}requency\\
   \textbf{U}ltra \textbf{H}igh \textbf{F}requency\\
   \textbf{S}uper \textbf{H}igh \textbf{F}requency}

\end{document}

Observação.O exemplo foi preparado paperheight=8cmapenas para mostrar as duas páginas em uma imagem.

Answer 2

Eu realmente não recomendo isso, pois envolve o uso de 2 notas de margem que parecem potencialmente complicadas, mas isso funciona:

\documentclass[a4paper,11pt]{book}
\usepackage[showframe,left=1.5cm,right=1cm,top=3cm,bottom=1.5cm,marginparwidth=5.5cm,marginparsep=1cm,outer=8cm]{geometry}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage{lmodern}
\usepackage[svgnames]{xcolor}
\usepackage{amssymb}
\usepackage[fulladjust]{marginnote}
\usepackage{ifoddpage}

\newcommand{\arrow}[1]{%
  \checkoddpage
  \ifoddpage
  \marginnote{\hspace*{-.5\marginparsep}\makebox[0pt]{\textcolor{red}{$\blacktriangleleft$}}\hspace*{.5\marginparsep}#1}%
  \else
  \marginnote{%
    \makebox[0pt]{\hspace*{.6\marginparsep}\textcolor{red}{$\blacktriangleleft$}}%
  }%
  \marginnote{#1}%
  \fi}

\begin{document}

  TEXT\arrow{%
    \textbf{H}igh \textbf{F}requency\\\textbf{V}ery \textbf{H}igh \textbf{F}requency \\\textbf{U}ltra \textbf{H}igh \textbf{F}requency\\\textbf{S}uper \textbf{H}igh \textbf{F}requency}

  \newpage
  TEXT\arrow{%
    \textbf{H}igh \textbf{F}requency\\\textbf{V}ery \textbf{H}igh \textbf{F}requency\\\textbf{U}ltra \textbf{H}igh \textbf{F}requency\\\textbf{S}uper \textbf{H}igh \textbf{F}requency}

\end{document}
