This is a discussion on Terk Indoor Antennas within the DTV | HDTV Reception and Antenna Discussion forums, part of the Over-the-Air (Antenna TV) category.
You probably dont want a powered antenna that close, but its impossible to tell, without more information, like an exact address TVFool plot.
I use the Terk HDTVa 18 miles from Needham.... but it is located in my loft, essentially pointed through the incline of the roof, rather than close to a window that faces in the correct direction.
In general, amplifiers on indoor antennas should be avoided unless you have splitters or long cable runs.
Thanks for the input as usual. I've got a friend in a tight bind for cash. She's getting rid of cable service and wants to go back to over-the-air for a year or so. I'm trying to get her the best bang for the buck without sacrificing reception but as I've learned here, it's pretty much trial and error. I think we'll go for non-amp first.
The one thing I like better about my Philips antenna is that the amp is variable. There are ten settings, starting from practically no amplification, to full power. I have that one set up in my kitchen, right by a window, facing northeast. (The transmission towers are southwest of here, so I'm essentially pulling in reception on that antenna through my home, through an internal wall, and out the back sidewall of the building.) The amp is at level 9 for best reception.
