| Summary:
We present the confirmation and characterization of three hot Jupiters,
TOI-1181b, TOI-1516b, and TOI-2046b, discovered by the TESS space mission. The
reported hot Jupiters have orbital periods between 1.4 and 2.05 days. The
masses of the three planets are $1.18pm0.14$ M$_{mathrm{J}}$, $3.16pm0.12$,
M$_{mathrm{J}}$, and 2.30 $pm 0.28$ M$_{mathrm{J}}$, for TOI-1181b,
TOI-1516b, and TOI-2046b, respectively. The stellar host of TOI-1181b is a F9IV
star, whereas TOI-1516b and TOI-2046b orbit F main sequence host stars. The
ages of the first two systems are in the range of 2-5 Gyrs. However, TOI-2046
is among the few youngest known planetary systems hosting a hot Jupiter, with
an age estimate of 100-400 Myrs. The main instruments used for the radial
velocity follow-up of these three planets are located at Ondv{r}ejov,
Tautenburg and McDonald Observatory, and all three are mounted on 2-3 meter
aperture telescopes, demonstrating that mid-aperture telescope networks can
play a substantial role in the follow-up of gas giants discovered by
textit{TESS} and in the future by textit{PLATO}.
