I have an amplified Astatic D-104 with the older T-UG8 stand. The Astatic manual
says to use a .01 cap in line with the white wire, and to use High impedance mic
only, which I assume it is.

They may say this for one of two reasons:
They may need DC isolation from mic to radio (should have a series cap
already... so this is not likely) or
They want to reduce low frequencies exiting the mic. This is the most
likely reason.
