NOTES:

IFI Model EFS-1 and Holaday Model HI-3001 field intensity meters used to measure E field. Calibrated loop antenna+HP power meter used to measure H field. Measured values corrected for calibration error and rounded off. 1Tri-band, Yagi, HF antenna mounted on a pole over a garage near single-story house. Antenna appx. 8-9 m above ground. 2Distance measured from appx. location under antenna base and in direction of maximum propagation.
