Brilliant Gary.
Your experiments prove that the ferrite filling of the Wellbrook could be snake oil!
Once I am all fixed up I want to build another loop with alloy tubing made into a circular loop of between 1.5 & 2 meters, I'd like this mounted on the gable end with a rotator.
The losses though on the coax will be down to the bifilar winding on the output toroid which I reckon could be around 150 ohms, I was going to reduce the secondary turns by 50% on mine to see what effect it has. A job for later in the year though.
One thing that comes to mind, even though you have your "loop" around the window Gary, the performance will be even better just a few metres outside, so it just goes to prove how well these single turn loops actually perform.
How is it on Long wave? Are you getting a good few continental stations?
