loop antenna construction ideas.

ok, many thanks.

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.

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..
