  We consider a nontrivial action of $\mathrm{C}_2$ on the type $1$ spectrum
$\mathcal{Y} := \mathrm{M}_2(1) \wedge \mathrm{C}(\eta)$, which is well-known
for admitting a $1$-periodic $v_1-$self-map. The resultant finite
$\mathrm{C}_2$-equivariant spectrum $\mathcal{Y}^{\mathrm{C}_2}$ can also be
viewed as the complex points of a finite $\mathbb{R}$-motivic spectrum
$\mathcal{Y}^\mathbb{R}$. In this paper, we show that one of the $1$-periodic
$v_1-$self-maps of $\mathcal{Y}$ can be lifted to a self-map of
$\mathcal{Y}^{\mathrm{C}_2}$ as well as $\mathcal{Y}^{\mathbb{R}}$. Further,
the cofiber of the self-map of $\mathcal{Y}^{\mathbb{R}}$ is a realization of
the subalgebra $\mathcal{A}^\mathbb{R}(1)$ of the $\mathbb{R}$-motivic Steenrod
algebra. We also show that the $\mathrm{C}_2$-equivariant self-map is nilpotent
on the geometric fixed-points of $\mathcal{Y}^{\mathrm{C}_2}$.
