  We demonstrate resonant detection of rf electric fields from 240 MHz to 900
MHz (very-high-frequency (VHF) to ultra-high-frequency (UHF)) using
electromagnetically induced transparency to measure orbital angular momentum
$L=3\rightarrow L'=4$ Rydberg transitions. These Rydberg states are accessible
with three-photon infrared optical excitation. By resonantly detecting rf in
the electrically small regime, these states enable a new class of atomic
receivers. We find good agreement between measured spectra and predictions of
quantum defect theory for principal quantum numbers $n=45$ to $70$. Using a
super-hetrodyne detection setup, we measure the noise floor at $n=50$ to be
$13\,\mathrm{\mu V/m/\sqrt{Hz}}$. Additionally, we utilize data and a numerical
model incorporating a five-level master equation solution to estimate the
fundamental sensitivity limits of our system.
