I had a rotator installed with the brand new installation of my outdoor antenna a month ago I thought I would have a need for it due to my true locals which are about 30 miles away to the southeast (versus southwest for Charlotte). As it's turned out, I rarely use the rotator except with one of my local stations which operates at low power and sometimes will pixilate if the boom of my directional antenna is not pointing to the southeast. However, again, for the most part, I just leave the rotator alone (pointed south to southwest for Charlotte stations) and this highly directional antenna seems to pick up most everything else off the side (without the antenna being pointed to my true locals).

With this being an eve mount 30 feet off the ground, it is very difficult for me to get up there. (It clears the A part of my roofline but sits right on the edge of the roof up on a tall mast.

I guess my biggest question now is the following. Is 5 NM(db) of gain too little to work with? I thought, at least theoretically, that anything above 0 was okay and that 5 or 10(db) would definnitely clean things up.

In may case, I get all of the stations in green and yellow but only one station in the red/pink section of my tvfool.com report. Maybe, it's a lost cause to get WAXN Virt Channel 64-1. There is a distance factor there of over 60 miles. However, I am not having any problems grabbing the other Charlotte networks, which are the same distance in mileage and some of them even a bit further than WAXN. Of course, I know some of these stations operate at lower power.

But again, when a tvfool report shows a station at 5NM(db), is it normally a lost cause in terms of trying to grab the station? I am thinking the answer is generally yes. Thanks again.

Thanks for your feedback.
Scott
