Anders,

I just saw the two videos. Now that is very impressive. It's not even tuned
either from what I can see. My pickup loop is like 6" in length also. Fun
stuff for sure

Lucky,
The loop in the picture is an untuned shieded loop. Do a google search
on shielded loop antenna or magnetic loop antenna.

There are a lot of benefits to a loop antenna. Low noise is the best
feature.

The simplest loop can be made from a piece of coax and the connector to
match the one on your radio.

You can start with an untuned antenna which is low cost and simple. If
you want to put more effort into it, try a tuned loop.

Have fun,
