Does anyone have any experience with an omni directional digital TV antenna?  I have the old analog TV antenna mounted on a rotor and then a cable down to a converter box.  It works pretty good but my computer is real fussy about stations.  If the antenna is off just a little it won't get some of the channels.

Our channels are numbered 1141 1142 1161 1162   for 4 and 6 and so on.

Always a 1 followed by the channel and then the last digit because those channels have more than one now.  In the case of a channel such as 24 it now is 1241 and 1242.

I'd just like to put up a good antenna that was omni directional to hook to my computer.

Thanks in advance to any help.
