Pixelated in Chicagoland

Hi all,

About 10 months ago, I made the decision to nix Comcast and go OTA for my TV services. I mounted an RCA ANT751 (combo UHF/VHF) to the existing satellite mast that my home's previous owner left on the roof, about 15' off the ground. I aimed the antenna directly at the tower using a compass. I ran some RG6 Quad Shield down to a grounding block, then into my house, into a three-way splitter, and then to each of the three tvs in my house.

Here's my issue: I get TERRIBLE reception on four channels, at least two of which are "green" stations that I should be alright with. The four channels are CBS (2.1), NBC (5.1), WIYY (20.1) and WCIU (26.1). The picture is constantly pixelated, freezing up, and utterly unwatchable. All of my other channels come in crystal clear, and I couldn't be happier with those.

The link to my TVFool report is here: http://www.tvfool.com/?option=com_wr...990035bec3bcf4

Can someone please help me out? Is there a way to fix this? Is there something I'm doing wrong? Thanks in advance.

Install a Winegard HD7082P antenna aimed at about , 131 degree magnetic compass.

Here is how to aim antennas , http://www.kyes.com/antenna/pointing/pointing.html.

Here are some strong and sturdy antenna mounts. http://www.ronard.com/909911.html , http://www.ronard.com/34424560.html , http://www.ronard.com/ychim.html , http://www.ronard.com.

Buy the ronard antenna mounts at solidsignal by typing the word ronard in the solidsignal search box.

Here are some places to buy antennas and etc. , http://www.solidsignal.com , http://www.winegarddirect.com , http://www.amazon.com.

The HD7082P antenna is to be mounted above the roof in a manner that is above the roof so that it is Up High for better reception of the Tv stations/channels to the south east at about 131 degree magnetic compass.

Locating the antenna so the antenna is not pointing through trees or buildings will improve reception.

Also install a Channel Master CM3414 , distribution amplifier.

The Tv's Must scan for the Broadcast Tv channels sometimes named the 'Air Channels' or 'Antenna Channels' in the Tv setup menu because the Tv transmissions travel through the air from the transmitting antenna to the receiving antenna.

Do Not scan for cable tv channels.

Electron,

Thanks for taking the time to respond. A few questions, though:

I already have an antenna mounted to a mast on the south side of my roof, aimed at 131 degrees, and I have already scanned for OTA channels on all of my tvs. Is the antenna you recommended so much better that it's worth replacing the one I have? Would the amp you recommended help my current set up?

Thanks again.

The HD7082 is a highly directional antenna.

A larger highly directional antenna will improve reception by rejecting multipath (reflected signals) that reach the antenna and rejects interfering signals better then the ANT751.

The HD7082P antenna is a larger antenna and as such is designed to receive more signal from weaker Tv stations.

The distribution amplifier increases the signal strength of all channels and this is good to keep the weaker signals/channels strong through out the system of multipul Tv connected.
