and where can I get some. I am going to build some of the famous slinky
beverages. Our local Target stores have been carrying them."
For a successful temporary 500' Beverage I put up to receive the recent
VK9 operation, I used an Amidon FT140-43 toroid core with a single
winding of 30 turns, with one end going to earth ground and the other end
to going the Beverage wire. I connected the 50-ohm coax up ten turns
You can order cores directly from Amidon by telephone at (310) 763-5770.
