Re: [IRCA] Active Whips Mounted Horizontally

The Wellbrook loops are broadband and generally work well with an SDR, and are less
susceptible to noise than a vertical or wire antenna.

     Russ,
 
       
 
       What about a broadband loop, such as the Wellbrooke
 ALA-1530S? I
       have one purchased, and setting the shack awaiting
 installation.
       Would this be a good choice?

       My understanding is that more electrical noise is
 vertically polarized than horizontally, so there
 could be an advantage in a horizontal antenna on that score.
 However, by putting the antenna
 in the horizontal plane, it is now no longer
 omnidirectional, but rather somewhat bidirectional,
 which may or may not be a good thing. 
 
 Where noise is a problem, one's optimum choices would be
 an inductive antenna. This will
 normally also be directional, whether it's an indoor
 tuned air core loop or an outdoor untuned
 superloop or flag. The former would also include a ferrite
 core tuned indoor antenna.
 
 These will all almost always be quieter than a wire antenna
 of almost any length, either 
 vertically or horizontally polarized.
 
 But since you are using an SDR, which is broadband, any of
 the tuned indoor loop options 
 would be impractical as they are not broadband.

  Forgive more of my silly questions,
  but here goes. I continue to try to fight, abate, and
 reduce
  local noise here in my suburban neighborhood. Deed
  restrictions complicate things further, since no visible
  outside antennas are allowed.
  
  Would mounting the active whips horizontally have any
 effect
  on the noise that they're receiving? I notice that
 noise
  seems to generally be lower using horizontal antennas than
  verticals in my situation?
