E- vs H-
« on: August 22, 2014, 11:23:05 AM »
I didn't see anything specific on this:
I'm setting up a new station.
Other than polarity and magnitude, why would one set up a magnetic receiver?  Simplicity?
Why would one NOT build an e-field station?
residential power line: 7.2kv, 100 meters
nearest 115kv transmission line: 10km (6 miles)

Well, Bill, I thought you got some answers over on Blitzortung Forum????

Its up to you. Combo system supplies better parameters for processing. Much of which has not been implemented. An efficient system will use both.
Peruse http://www.nssl.noaa.gov/users/mansell/icae2014/preprints/Chen_64.pdf and if somebody figures it out, let us know.

Each type of detector has advantages and disadvantages, among them being:

H-field is more immune to placement with respect to foliage and structures, and might be useful for direction finding with two orthogonal coils/ferrites.  E-field can detect polarity.

Having both will likely, eventually, enable two interference mode thresholds and more flexible functionality.
