Attenuation depth depends on the shield & conductor resistance. RG11/6 tends to have a bit more resistance so the attenuation null is not as deep. But you should get at least 23 dB out of; /archives//html/CQ-Contest/2016-07/msg00303.html (12,754 bytes)

It tends to be made with a copper clad steel center and Al shield. That depends on skin effect, so RF res; /archives//html/CQ-Contest/2016-07/msg00308.html (11,986 bytes)

Specifically, the use of type 3 stubs, where we use two 1/8th wave stubs in parallel instead of a single 1/4.
