YES!  I LOVE fan dipoles.  A HIGH 80/40 fan (higher than 50 ft) is 
likely to be a good match to 75 ohm coax.  Mine are at 110 ft, and I 
feed them with Belden 8213 (very low loss foam RG11). They also work 
quite well on 30, 17, and 12M.  A LOW 80/40 fan, and any 20/15/10 fan, 
will be a better match to 50 ohm coax.

For construction ideas, see the pieces on my website about antennas for 
limited space. There's a text document and a Power Point.
