MAGNETIC MEASUREMENT AND MONITORING ANTENNA
Omnidirectional mobile antenna with magnetic base for VHF DAB digital terrestrial bands. Built in two models, ARM1DAB.A 174 - 208 MHz block 5A ÷ 9D and ARM1DAB.B 195-240 MHz block 8A ÷ 13F. The protective UPVC cover also protects the antenna from strong and violent atmospheric agents. The antenna is electrically grounded to perfectly protect the radio devices connected to it against lightning strikes. Quick fixing is achieved by means of three strong magnets positioned 120 ° below the reference disc.
