[Towertalk] Help needed Cushcraft R7000+ 80m add on

[Tord E Julander]

Hi out there,

We need to get in touch with someone having any experience in assembling
and using an R7000+ vertical w 80m add on kit.
We're presently helping a local Oldtimer, to install an antenna bought
second hand. Fiddling a lot getting the thing to resonate within its
specified bands.

The manual describe the use of 3 counterpoise wires, each 20ft long for
80 meter use. These are left out here and need to be replaced. The
manual describes the use of an  "Anti-Resonator" to be installed in each
of these wires to avoid detuning of the higher frequency bands.

My  question is: What kind of circuit is this "Anti-Resonator", we need
to construct a sustitute to the original part,  in order to get this
antenna to resonate properly on 8 bands.

Yes,  there might be spares to order from the Manufacturer but....

Any ideas Please?
