AMATEUR STATION E
Station E was located at a single-story residence. Two antenna systems were examined.
(1) 40 m Wire Antenna
One antenna was a "40-meter," center-fed, half-wave dipole antenna (total length approximately 20 m). This antenna extended out over a sidewalk located next to the residence. The dipole was roughly horizontal, with the two ends being about 2.5 m above ground and the center located about 4 m above ground. This antenna was used by the operator to transmit at HF frequencies of about 7 and 21 MHz. The ham shack was located inside the house about 5 m from the closest segment of this antenna. Measurements were made both inside and outside the house. Results are given in Table 16.
(2) Multi-band Vertical Radiator
Field strength was also measured relative to a multi-band "trapped" vertical radiator mounted
on the roof of the house above the ham shack. It was attached to a chimney and was positioned approximately 2-3 m above the ceiling of the ham shack. This antenna was used to transmit at HF
frequencies of about 14, 21, and 28 MHz.
Results are given in Table 17.
