Topband: Length of Beverages

[Cqtestk4xs--- via Topband]

I'm planning on putting up some Beverages for the fall  season...primarily 
for use on 160.  Unfortunately, they have to be taken  down again in the 
Spring for crops.  The good news is they can be any  length up to around 
1200-1300 feet.
 
Many have said that around 880 ft is the "sweet spot".  Is  there any 
advantage to going up to around 1300 feet?
