[TowerTalk] antenna patterns of antennas in forest, over varying soil

[jimlux]

Here's an interesting report done by SRI during the late 60s, early 70s.

"SUMMARY OF MEASURMENTS AND MODELING OF THE RADIATION PATTERNS OF SIMPLE 
HF FIELD ANTENNAS IN OPEN (LEVEL) TERRAIN, MOUNTAINS, AND FORESTS"
By Barker, Taylor and Hagn.



They measured far field patterns with a probe towed by a helicopter for 
various HF antennas in forested and un-forested areas (Lodi, Lake 
Almanor, and Thailand)

dipoles, OCF dipoles, slant wires, inverted L, etc.
