[SixClub] Different 6M Antennas Different Noise-Level

[donroden at hiwaay.net]

Trying to use an 80 meter antenna on six is a roll of the dice.

Instead of a predictable "fat figure eight" pattern of a six meter dipole,
there will be many peaks and many nulls in the pattern.  The long  
dipole may even be acting like a longwire with directionality off the  
ends.

What the writer is saying is that somewhere in his neighborhood, there  
is a noise source that the delta loop "sees" but the dipole doesn't.  
I've seen random length antennas perform as good as, or better than a  
dipole , and
sometimes as well as a beam IN SPECIFIC DIRECTIONS.   It's good to  
have the ability to be able to switch antennas. Sometimes, you get a  
nice surprise.
