Wind your own coil...
Quarter inch diameter copper tube (50 foot coil of refrigeration tubing) from
the Home Depot, Lowes, etc. and a 6 to 8 inch coil form ( cardboard tube for
casting cement footings, from same stores)...
\Use a hammer to flatten the end of the tube and drill it for a sheet metal
screw.. Use the screw to attach the end to the cardboard form... Takes two
people, preferably 3,,, Roll the tube to wind the copper tubing around it...
Space the turns by the tubing width, a quarter inch...
20 turns will be ~10 inches long at 2 turns per inch... You can leave it
fastened to the tube, or remove it... The carboard is transparent to RF...
This will use 43 foot of the tubing...
You can wind the remaining tubing if you wish...
Then a variable cap, and you are in business with an L match....
