Best Roof Mounted FM Antenna


I am considering buying a Ron Smith Aerials outdoor antenna and heard that they are the best on the market. Is this a good choice? Since this is directional, would it be necessary to use a rotor? Thanks.

I have one of those $20 Radio Shack roof FM antennas that I've had since 1980. They do work very well !! I do not currently use it because the TV antenna allows me to use a TV in that room as well. There are lots of stations around DC even without cable.
My mistake - the rotor is channel master and the antenna is antenna specialities.
i'm not familiar w/the ron smith aerials antennas, but i use an antenna performance specialties aps-13 to great effect. it is directional, so ya prolly wood need a rotor, unless yer on a fringe area, & all the stations are in one direction.

in my case, i'm ~60 miles nw of the stations i listen to, (wpfw & weta - know them sugarbrie?), & i'm near the bottom of a ~1500' ridge, on the nw side. so, the ridge is between me-n-the stations. w/the aps-13 on the roof - no fancy high-mounted tower or anyting - i get excellent reference-quality sound thru my onix bwd1 w/soap p/s tuner. for info, see:
