Default Need advice on how to fine tune OTA reception

I am in the process of installing an antenna to grab OTA signals from the Savannah, GA market (about 30 miles away). I have assembled a DB8e from Antennas direct, propped it up in the attic and pointed it in the general direction of the towers (the important ones are all in the same place). I was happy to see I got most of the channels I wanted. I think the TV scanned 12 channels, but all I really care about are the main networks (for sports mostly).

Anyway, I could use some advice on how to fine tune things. A couple of the channels I want are pixelated or freeze a little. I am thinking that fully installing the antenna and orienting it properly will help. I also need to split this signal once to go to our bedroom TV. This split will take place about 30 feet from the antenna, with total runs to the TVs to be about 50-60 (over RF6 quad). So at this point I'm thinking a pre-amp may be helpful to boost the weaker channels and help with signal loss.

I would appreciate some thoughts on the process from here. Today I will mount and reconnect the antenna directly to the TV and see what I get. If I still have issues with some channels, is a pre-amp the next step?

I would include a TVfool map, but their current database doesn't even show about 1/2 the key stations in Savannah.

Thanks for your help!

Welcome, maui19

To give you accurate advice, we need some kind of report. We are aware of the problem with TVFool reports. The latest database that they are using is ALL SCREWED UP. If you can give us the last part of the link, because you do not yet have 5 posts, we can get a rough idea of your signals; like this:
?option=com_wrapper&Itemid=29&q=id%3de6a46686a80dec

If you are willing, you can give me your address or coordinates of your antenna in a PM and I can do a report.

At the bare minimum your city and zip code.

Which channels are giving you trouble?

First you get the signals good for one TV, and then split.

It's RG6 not RF6.

A preamp or distribution amp might help, be we can't be certain yet.

I guess you already know that an attic location for an antenna isn't ideal.

A antenna mounted in an attic will loose about 1/2 of the available signal strength from any station surrounding your location, an eve mount would be a good choice, but not knowing the surrounding terrain we would be just guessing, if you up on the roof do you have a clear line of sight from the roof peak ?(please be careful as we don't need any accidents)

Other houses or large trees in the way will affect the signals.

We will wait for the report when you can post it. (or if Rabbit has done one for you)

That helps, but we don't know where he is located that is 30 miles away, and which channels are the problem channels.

OMG are my posts ever going to be "approved" for this thread. It is like watching paint dry. No wonder there is so little activity here. FWIW I do appreciate all of you guys who are trying to help.

Hmmm...is the trick simply to have 5 posts? (I apologize for the obvious padding...)

Mine arrived yesterday. My plan is to add the CM pre-amp to see if it fixes the minor signal glitches, and enables us to pull in FOX. I'm not worried about WTOC/CBS any more because I just discovered we get it on Playstation VUE.

If the pre-amp does the trick, then I split the signal to the second TV. If that works, then I figure out which OTA DVR to add.

FWIW I get (I'm doing this from memory so I apologize if I forget something):

WSAV-HD 3.1 (NBC)
WSAV-CW 3.2
WSAV 3.3
Four versions of ETV/PBS 16.1-4
WJCL 22.1 (ABC)
And a couple other weird ones I can't recall exactly and don't care about, such as Laff, etc.

Well the preamp didn't seem to help things. I think I am going to try some different locations for the antenna.

I moved the antenna deeper into the attic, farther away from an air handler and some 2x4s and that did the trick. Everything comes in nice and clear--a far better picture than I ever got from DTV.

So now I need to get smarter about OTA DVRs. Can anyone point me to some good info?

Thanks!
