I have 2 dipoles in my attick. One is attached to the center beam and the other is suspended just below it. Both work awesome. Can not tell the difrence in either of them on the recieve end and both have talked around the world hundreds of times.
And your 25' dipole i believe is tuned for 17m. 468/18.150= 25' so if its 25' the center freq is 18.150mhz not near 11m or 10m unless you have a good tuner. My tuner tunes a 32' dipole all the way from 6m to 75m.
Another thing too is a lot of people on 10m and 11m run vertical and would be cross polarized if your on the dipole.
