say to put the 2 (or maybe 3) ferrites at 90 degrees.
The picture on the same page http://en.blitzortung.org/cover_your_area.php
shows the ferrites in a 120 degree delta
What should I do?
Have I missed some documentation/description somewhere ?
thanks
Have a look into the Assembly instructions chapter 4.2: Antenna
Scroll down and you will find a picture with 2 horizontal ferrite antennas 90° and one vertical in 90° to them
but....
why the picture of three in a delta.? There is no description of deltas in the instructions ?
Which one should I be building
Why the picture of the delta if they are all meant to be at 90°
I have read in a post somewhere in the forum (maybe it was Egon) that it makes not a big difference if there are 2 or 3 ferrites. As you can see on my webpage I'm using 2 on ground level . Both are schielded to the south side due to my home in the back but I still receive a lot of signal from the south direction. At the moment there is low activity in Europe but when comming closer to Italy Spain, France... I'm always on page 1 - 3 seen on the station-list (http://de.blitzortung.org/station_list.php?session=1) whis very good efficiency.
The complete system is not only plug and play and I would recommend that you will start with 2 or 3 horizontally as you can see on my picture. I started with a piece of hard-paper, fixed the ferrites on it with some cable ties and tested for some days on different positions. I you have found a good position you can try with one vertically. Don't use them all vertically mounted on a wall. Check each position and configuration really for at least 1-3 days to get a valide response since the conditions will change all the time with the lighnings, noise, weather,...
So take your time until you have found the best position at your location. Then finalize it (and make it nice ). I recommend also to start with automatic settings. If you start with manual settings you will have too many variables changed at the same time.
If you have neighbour station check his results, compare and find a new location.
Good luck!
