Need help selecting an antenna setup in Rural East Texas

Thank you for the additional information about your location. When I look at the satellite photos, I see your location at the end of an access road off the main road.
The satellite image from the tvfool interactive map browser, using Google maps, was done in the winter when the leaves were off the trees. The image from Bing maps, if I have the correct location, shows a lot of trees that might block your signals. You will need to find a location for your antenna that avoids the trees as much as possible. A high gain UHF antenna aimed at about 14 degrees magnetic and a preamp should work. My only concern is about NBC. If KTAL is too weak, you will need a rotator or a separate antenna, and single channel injector for KETK. CW is also in a different direction. Antenna: Antennas Direct DB8e with both panels aimed in same direction, or 91XG, or Solid Signal HDB91X. Preamp: Antennas Direct Juice or Channel Master 7778. If the antenna is outside, the coax shield should be grounded with a grounding block that is connected to the house electrical system ground with 10 gauge copper wire for electrical safety and to reject interference. For further compliance with the electrical code (NEC), the mast should also be grounded in a similar manner to drain any buildup of static charge which will tend to discourage a strike, but the system will not survive a direct strike. http://forum.tvfool.com/attachment.p...9&d=1441917363 |

My account was activated today so I can see the images now. :D
Thanks again for posting for me. Here is a more representative picture of the trees since we had some timber cut. Also, the section of trees in blue have now been clear cut. I'll take a look at the options you provided and get one of the antennas and preamps on order. Does any one have the potential to be significantly better then the other? If we can pull in several channels we'll be happy. Does anyone know if our Weboost cellular signal booster will have any negative effect on the tv signal? Is it ok to mount on the same mast? Also, was there much improvement in going from 20' to 30' height? I'm guessing that will be somewhat dependent on the trees in the direction of the signal. |

Most of your channels are at the low end of the UHF band. The DB8e, with both panels aimed in the same direction, has more gain than the 91XG in that part of the UHF band. https://www.antennasdirect.com/cmss_files/attachmentlibrary/Technical%20Data%20PDF's/DB8E-TDS.pdf https://www.antennasdirect.com/cmss_...y/91XG-TDS.pdf Quote:

I just found this one on maps.google.com that is even more current. The gaps are starting to fill in with undergrowth but it isn't over about 10' tall. Attachment 2478 |
Did the the 30' report look considerably better than 20' or about the same?

Not much difference.

Just wanted to take a minute to say thanks. I got all of the components and have been so busy with other projects that I haven't installed the antenna yet. Tonight I wired everything together and put the antenna on the back porch to see what stations I could pull in.
I currently have 29 very clear stations (a few duplicates) so I'm going to be very pleased once I get the antenna mounted on the mast. Thanks again for your help. These channels come in better than those at our home and we're in the greater Houston area. Obviously I'll need some help selecting the correct antennna for that location once I complete this setup. I fell for the Leaf Mohu marketing :( |
Thanks for the update. It sounds like you will be OK.
