Here follows the field strength data of the
RoomCap Antenna.
This allows, among others, to determine the
security distance for the EMF regulation.
Field measurements performed 5th.July 2006
------------------------------------------
performed by HB9BWN and HB9ABX
sport field Bachgraben / Basel-Allschwil
Measured antenna:RoomCap 20m (w/o top capacity)
Transmit frequency = 14 Mhz
Distance = horizontal distance sensor to radiator
Height = height of sensor above ground
Ant-Height = height of Varylink above ground
Input power to antenna = 100 W
E-sensor / Ant-Height = 50cm / 100 W
------------------------------------
Distance = 10m
Height = 30cm / 1m / 1,5m / 2m
4,6 6,0 8,3 9,1 V/m
Distance = 5m
Height = 30cm / 1m / 1,5m / 2m
8,8 11,7 13,2 14,7 V/m
Distance = 4m
Height = 30cm / 1m / 1,5m / 2m
10,8 13,3 17,1 18,2 V/m
Distance = 3m
Height = 30cm / 1m / 1,5m / 2m
14,2 20,2 22,3 23,4 V/m
Distance = 2m
Height = 30cm / 1m / 1,5m / 2m
21,5 34,6 41,2 42,6 V/m
H-sensor/ Ant-Height = 50cm / 100 W
-----------------------------------

Measuring instrument:
Wandel&Goltermann
Type = EMR-200
Serie = BN 2244/21
H-sensor = 12.1 / 2244 / 90.28
E-sensor = 8.2 / 2244 / 90.20
