Topband: Pennant Antenna

[RICHARD SOLOMON]

I put up a Pennant Antenna, facing NE and am comparing it to the Loop
Antenna I have up. So far, the jury is still out.

But, one thing I noticed is that it is gangbusters on 80. Which leaves me to
ask:

If a 14' X 29' Pennant is so good on 80, what if I double the size ? To 28' X
58' ?? Would that work even better on 160 ? 
I don't have nor have I used EZNEC so I cannot go that route.

Thanks for any input,
