The directional coupler I'm building calls for a couple of short pieces of
RG-303, apparently an obsolete teflon-insulated coax. I haven't been able to
find any of it. I need only about 6 inches (yes, inches!) of it. It is used
to carry the power--just 100 watts in this application--through the toroid
cores in the pickup unit. The coax simply runs through the middle of the
toroids, which have a winding on them. The cores are small T68-2 types, so the
coax must have a pretty small diameter. RG-58 is a tight fit.
Anyone have 6" of the RG-303 lying around to sell; or any suggestions for a
substitute coax?
Tnx and 73,
Tony, N2UN
