I've been looking through this site for a couple of weeks now. I must say I'm quite impressed with the wealth of knowledge and helpfulness and politeness of the members here. I read back a year in this thread alone. In addition, there are reference links offered to other posts which in turn lead to further research. I thought I was never going to get through everything, but I now have a better understanding of the terminology and believe I am ready to get some advice.
Like others, I came here with the intent of doing away with cable for obvious reasons. Of course, who wouldn't mind an attic install under the right conditions, but I'm going with a roof mounted unit. With that said, here is my TV Fool report based on my exact coordinates and a 25' height.
I played with a +/- 5' height variance and didn't notice much of a change, but I'm no expert at deciphering all of the given information. With the exception of WSKY-TV (RC 9) at over 44 miles away, all of the stations I'm after are LOS. At 30', it would also become LOS. This is a station I wouldn't mind receiving. It is one of three VHF channels over a 13 degree angular spread (RC 7 and 13 are the others).
So based on my reading, I've seen two or three antennas recommended over the last year by various folks on the forum. Looking at other reports similar to mine, I'm guessing I may need the good old RCA ANT751R.
Regarding mast material: If the antenna mast were made out of a non conductive material, there wouldn't be a need to ground it, only the antenna itself via a grounding block. Maybe I missed it somewhere, but there must be a reason why masts aren't constructed with non conductive materials. Just curious...
Thanks much in advance for the help!!
