Narda 1970's Isotropic Radiation Monitor
joeqsmith:
Pictures are of an old 70's broadband isotropic radiation monitor. The 300MHz 20mW/cm^2 H field probe was the only one included with the set.
The plastic selector knob was gone but the metal insert was still on the unit. The knob shown I believe was from an old HP scope. The rest of the unit appears original and in near mint condition. The battery still had a very small charge but would need to be replaced.

Showing the model 8631 10-300MHz H field probe. Also shown is a page from the manual that shows the basic construction.
joeqsmith:
Pictures showing the model 8616 radiation meter. The paint cracked when I removed the cover. I think this is the first time this unit was taken apart.
joeqsmith:
The battery pack appears to be no longer available.
joeqsmith:
I doubt you would find too many wooden spacers in a modern battery pack.
