Paul: I believe that Part 15 Section 209 is also totally applicable. It says: § 15.209 Radiated emission limits; general requirements. (a) Except as provided elsewhere in this subpart, the emissions from an intentional radiator shall not exceed the field strength levels specified in the following table: Frequency (MHz) Field strength (microvolts/meter) Measurement distance (meters) 0.009–0.490 ................... 2400/F(kHz) 300 0.490–1.705 ................... 24000/F(kHz) 30 1.705–30.0 ..................... 30 30 30–88 ............................. 100 ** 3 88–216 ........................... 150 ** 3 216–960 ......................... 200 ** 3 Above 960 ...................... 500 3 Why don't you think this section applies? Also, the 3 meter limit is not for the antenna itself but rather for the sum of the transmission line (coax) and antenna as stated in Section 219: (b) The total length of the transmission line, antenna and ground lead (if used) shall not exceed 3 meters.
