Hi- I hope to be out to my rural property in a year or less and am wondering about tv antenaes- the external kind. Currently on a battery operated set outdoors there I can pull in 4 channels quite clearly, but when I go inside only about 2 channels clearly and 1 poorly. Any one have any experince with outdoor tv antenaes? What should I look for? Does price make a difference in reception? Who makes a good one?
