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.
