AMATEUR STATION H

Station H was located at a single-story residence. A large horizontal loop antenna was the subject of measurements at this station. Its shape was that of a large rectangle extending around the

perimeter of the back yard and over the roof the residence. This antenna is essentially omni-directional. It can be used for several frequency bands and has been referred to as a "loop

skywire" antenna.

The leg of the rectangle extending over the roof of the house was about 20 m in

length. The two perpendicular segments were each about 21 m in length and extended back across the roof toward the backyard, over the respective edges of the yard, and up the rather steep slope of

a

hill at the rear of the yard. The remaining segment of the rectangle was about 20 m long and followed the ridge of the hill to complete the loop. The antenna was fed at a corner of the antenna over the roof. The height above ground to the antenna ranged from about 8 m at the feed point to as little as 1-2 m along the ridge of the hill. The antenna constituted a full-wave loop at about 80 m wavelength (3.75 MHz). Measurements were made both inside and outside the house at transmitting frequencies of approximately 3.7, 7.1, 14.1, 21, and 28 MHz. Results are given in Table 25.
