CTUN Installation Considerations
VHF Field Tunable Antenna
CTUN-NB-VHF
The CTUN-NB-VHF is a field tunable antenna that operates in a 3 MHz bandwidth across the frequencies of
150-174 MHz. Once tuned to the desired frequency, the locking mechanism holds the tuning assembly in place.
This omni-directional, vertically polarized (from bottom edge) antenna can be concealed in a tissue box on the
rear deck of a vehicle, placed between two boards, hidden in a sign, or mounted in countless covert ways.
