Separation to MF-HF, VHF, and UHF antennas
The LT-3130 Antenna Unit must be installed with a 360° clear view of the sky. However, minor
obstructions such as a mast will not degrade the antenna performance severely, if a separation
distance larger than 15 times the diameter of the obstruction is kept.
