Central VA Antenna Recommendation & Mounting Info Request

TVFool - http://www.tvfool.com/?option=com_wrapper&Itemid=29&q=id%3d1ddae1108cd9e9

I borrowed medium directional unknown brand & model, about 6'L x 4' W https://dl.dropbox.com/u/46204484/2013-02-17%2015.54.12.jpg and did some tests this weekend. Channel 48 (4.1) had 10% signal (according to my tv) inside 1st floor and inside 2nd floor. Didnt try attic as there was 0 improvement between 1st and 2nd floor,. Antenna laying on the ground outside the signal went up to 25%-30 and was viewable. Only 1 other channel came in clearly with no "lag". Holding the antenna on front porch, so about 8' elevation, brought the signal up to 60%. I did not verify all the channels at this point, probably should have.

1. What antenna is recommended for this location? If I get UHF only antenna will I be unable to view channels 7 & 9, but will be able to view Fox5.1 because it is actually on channel 36?
2. Can someone provide a link covering roof mounting? I thought it was all done with tripods, but then I was looking at some pics and it seems that passing the mast through the roof into an attic mount makes the most sense.

I'll leave the antenna mounts to the experts. I'll only cover the antenna part. You definitely need VHF-Hi & UHF. If you want to go with separate antennas, then I recommend an Antennacraft Y10-7-13 for VHF & an Antennas Direct DB8. I'm recommending the DB8, because it's less directional than a yagi, & your UHF stations are spread out in one specific range. If you go with combo antennas, then either the Winegard HD7696 or 7697, or the Antennacraft HBU44 or 55.

The antenna you tested with is a UHF/VHF antenna, which is the correct antenna for your needs. However your testing methods was only at ground level. You really need to put the antenna on the roof for max signal. Height is the key factor when trying to receive signals. I would suggest the HBU-22 from Radio Shack.

When you put it up, point it North. In the picture of the link I posted, the right side of the pic is the front of the antenna.

You can certainly try out the antenna in the attic and see if reception improves, but 44 miles away is at the outer limits for an attic antenna..

As for mounting it, I prefer not to touch the roof If I don't have to. I have mine mounted on the chimney with chimney straps from Radio Shack. They also sell 5 ft and 10 ft masts.

If you're only interested in the Washington stations, a Winegard HD7694P (combination UHF plus VHF-high antenna) up on the roof/chimney and aimed at around 4 degrees true would probably work just fine. If you were also interested in receiving the Richmond and Baltimore stations (down to around WWPX-12 or maybe even WUTB-41 on your TVFool report), you'd go with the generally recommended long-range prescription, which is a DB8 (for UHF) mounted 2 or 3 feet above a Y10-7-13 (for VHF-high) on the same mast, on a rotator, joined together up at the mast by a special UVSJ signal combiner, and with a single coax from the UVSJ down to your tv. An amplifier could also be added to the long-range system afterwards if necessary to strengthen some of the weaker stations.
