There is a Canadian Ham on the magnetic loop list who makes first class
butterfly caps(you assemble) less than $100 to my home.

If you are making a home-brew loop why not make the capacitor too? My
loop works fine at 100 W input but not yet tested at 500 W. I borrowed the
capacitor design concept but the implementation details are mine. Capacitor
components are hardware store copper pipe, copper pipe couplers, and PEX
tube.
