Well at least hot glue is recyclable as long as I don't get it too hot ;-) Doesn't a RF choke need low Q ? Or at least very lousily at 1.5 Ghz ?
Will connect some more receivers today to get a better idea about how well it works my Brandywine is the most deaf, will start with that one.

I'm sure that's high performance microwave certified hot glue (from Lowes) and not the common garden variety kind (from Home Depot).
