NOTE 1: At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by
absorption and reflection from structures, objects, and people
Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land
mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically
with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site
survey should be considered. If the measured field strength in the location in which Loop™ is used exceeds
the applicable RF compliance level above, Loop
performance is observed, additional measures may be necessary, such as re-orienting or relocating Loop
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
