Monitoring facilities at Westerbork Observatory

Fixed monitoring station.

Azimuth range (in °):	0 - 360
Elevation range (in °):	0

Characteristics of the facility:

Frequency range	Frequency resolution	Antenna gain	Sensitivity	Omni-directional antenna
(MHz)	(kHz)	(dBi)	(dBW/MHz)
200-1000	3	9	-78 to -83	yes
1000-2600	3	1.2	-96 to -100	yes

Mobile monitoring station.

Azimuth range (in °):	0 - 360
Elevation range (in °):	0

Characteristics of the facility:

Frequency range	Frequency resolution	Antenna gain	Sensitivity	Omni-directional antenna
(MHz)	(kHz)	(dBi)	(dBW/MHz)
0.01 - 80	0.15			yes
80 - 1600	0.15	2	-127	yes
1000 - 3000	0.15	0	-125	yes
80 - 1300	0.15	6.5	-131	no
400 - 3000	0.15	5 - 7	-131	no

Note: Sensitivities can be improved by 30 dB, using lna and appropriate filtering.
