Efficiency of Vertical
The antenna is a 7.5 m vertical used for 40m and up with an ATU. Due to space limitations I have radials in only about 90 deg of the circle around the antenna. 30 wires app 5m long on the ground. How will this affect the efficiency in the directions with no radials ?? Cant figure out how to model radials on/in the ground in MMANA... /js |
