Re: Tips to improve LAA+ Performance?

Hello Simon

Sturdy looking loops and it looks like you've put a lot of effort in to them.  

I was wondering how these would compare to Chris's idea of bicycle rims.

The amp likes low inductance..

So bigger dia tubing the better (there is a point of low return dont be silly and use 3 inch tubing.)

To improve more then use 2 or 3 loops in parallel, spaced say 6inches apart.

Or even better use 4 crossed parallel loops..

To improve hf over lf use smaller dia loops..above pic shows loops of 80cm ( circa) squares..i have the preamp switchable directions, hence why 8 loops in pic.

Above works well from dc to 20mhz..
