Hi Jamie,
I assume you are referring to short RX verticals similar to those used
in the Hi-Z and other arrays with a 20 to 25 ft vertical element.
I have extensive experience with these and have the HiZ-8 on 160, the
passive BSEF-8 array with 25 ft "umbrella" verticals on both 160 and 80
meters and also have the YCCC 9 vertical array. I have never experienced
a situation where I believed there was a need for any type of choke or
bleeder resistor to quiet noise. As Tree has pointed out with an active
array such as the HiZ or YCCC-9 this may create issues with the array
amplifiers
After a proper installation to ensure good RF connections in the system
and address any common mode noise condition that may exist, all of these
are extremely quite at my QTH without the need for "bleeder" components.

Since verticals are know to be "noisy" on receive, and a fix is a rf
choke or bleeder resistor to ground, anyone try that on short
verticals used for receive only to quiet some noise?
