[Hi-zreceivingarraydiscussions] Hi-Z 4-8 Pro

[John Kaufmann]

Hi Larry,

 

I had the exact same thing happen to my array just recently.  I disconnected
the antenna feedlines one at a time until removal of one feedline made the
noise go away.  It turns out a critter had chewed into that RG-6 feedline.
Because the feedlines carry DC to the preamps, a cable fault, like a partial
short of the braid to center conductor, will result in noisy current flow
across the breach.

Hi all,

 

    For some reason I have experienced a sudden increase of 20db noise floor
increase in the 4-8 pro array....  Has anyone else ever seen this and what
should I look for?

Guess I may need to head to the Remote and try and trouble shoot his.  The
temperature is about right for antenna work anyhow...  been around 10-20
degrees all week.

 

Merry Christmas all,

Larry  K1UO
