Antennas for System BLUE - Mini Guide

[Egon]

For me it is also hard to believe, but it's not an antenna, its a probe, as Richo repeatedly emphasized.

Its exelent, thanks Richo!

Hello to all...
Thanks for the mini guide Richo.
I just want to ask a few questions.
I want to make a mini loop for my blue system with 2 simple coax loops (no trafo small loop 38cm).
I dont have a clear connection guide to the blue board. Is it easy for anyone to make a simple diagram of the wiring ends?
May i use 2 or three of them? What about grounding? 
Thanks in advance and keep up your special job.

Many have questions about antennas
I made a mini guide to getting started making antennas

Good luck

...If you wish I can help with ready-wound transformers

Excellent guide, I have just signed up on the forums and for a system blue and think I'll start by building antennas and see what kind of VLF noise I pick up in my home.

I tried to access http://www.richos.dk/TOA but it seems to be down?

Richo,

I have started making the H field Copper tube Loop antenna shown in your mini guide and also from http://users.skynet.be/DanielV37/Project...m#Hardware.  I have produced 3D print files for the top & bottom Junctions from the drawings on that site and have published these files at http://www.thingiverse.com/thing:1713141 .  I have included attribution to the design as best I could find reference.  Can you have a quick look at this url and advise if any further attribution is needed.

thanks

My Red and Blue are currently side by side, both with ferrite H field antennas. The Red were shielded with the plastic tube/copper tape method, and the Blue not shielded.

The Blue performance was not quite as good as the Red, so last weekend I swapped the antennas over so the Blue was shielded. The Blue performance hasn't really changed much, but the Red performance has dropped through the floor. So next weekend I'm swapping them back again!

Have a lot of suggestions for changes - water intrusion is a challenge

By the way - time has run from this antenna - it is too large, and intended for System GREEN
Make it of brake tube 5-6 mm and a diameter of ~ 40cm
Most effective is the "Möbius" with transformer

What size PVC pipe are you using for the e-field antenna? I'm going to try and stop at Home Depot tomorrow to pick some up. Need to get mine out of the attic!

32mm inside can do it

Hi all,

I have a new System Blue (#1588) and have been testing H-field performance with a 2 axis wire loop antenna with 20 turns @ 38cm diameter (with the jumpers made on the back of the H-field antenna).

Can anyone comment on the relative performance between the simple loop antenna, and the ~40cm 'brake tube' möbius antenna that RichoAnd mentioned a couple of posts back?

Thanks,
Peter

Minor difference if any
