loop antenna construction ideas.

i tried making a loop with 4mm copper wire and found the reception very poor, i read on a prior post it should have used something thicker to lower resistance.

so what should i use for an attic install, i see on ebay you can buy copper tape or do have some RG213 up there it might be long enough.
how long should it be, 3 Meters enough?

using the CCW HF/VHF Loop antenna amplifier.

Thicker dia the better. But no real gains after 25mm dia.
its to lower inductance not resistance..
2- 4 small loops in parallel works better..as lowers inductance..

no bigger if single than 1m dia..any bigger hf suffers..

You could use an aluminium bicycle wheel (which has good inductance properties) as demo'd by Chris on an introductory video of the low-cost loop antenna amplifier...
See: https://www.youtube.com/watch?v=iegoJ0gTdBI
I have one installed on an attic wall that does work within the constraint of being indoors.
