[Antennas] Newbe with First Question

[johnkin]

Greetings to the Group,.

This is my first time on here so I hope you all understand my question. 
I have recently built a G5RV Jr. that I plain on using portable. I have 
a 21 foot mast that is very easy to set up and take apart. The length on 
each side of the antenna is 26 feet and I have an extra 40 feet of rope, 
to add on each side. Each side will be tied to a stake, Making it a very 
shallow inverted Vee.

My question is this. At what point does an antenna turn from an Inverted 
Vee to a somewhat flat antenna? Is there a gray aria between 120 degrees 
and 180 degrees?

I have heard some say they have a drop of 10 feet or a bit more and it 
seems to work out just find. So this is why I ask the question.

I am looking forward to your replies.
