this is the one i have

http://www.radioshack.com/product/in...ductId=3730720

yes i run 4 tvs. well 2 at thew moment but i have all 4 rooms wired. the antenna coax runs down to the other side of my house, down the eve into the telephone/cable box near my electrical panel. inside the cable electrical panel is where the the cale come from all 4 rooms. All the rooms were hard wired when i the house was built in 2006. i ran the antenna coax to the inline amp, then the amp to the 4 way splitter and connected all the rooms.
----------->
antenna ----------->in line powered amp----->4 way splitter----------->
roof 50ft ----------->
----------->

there is a grounding block from the cable guy in the cable panel. how do i ground for lightning and surges to?

update:

So i disconnected the 4 way splitter and just ran the antenna coax tot he amp to my living room coax. the picture hasn't cut out once, i get all the channels except 12-1 12-2 (also 43-3 43-4) seems to be off air or something. anyway. To me this would indicate that the 4 way is interfering with my reception and i am losing db's? So would a 4 way amp help so i could have all 4 hooked up? Also i believe i have over -20db loss with the long cable run, splitter and the long cables going to the tv's.

I recommend a Winegard HD7000R antenna with a Antennas Direct PA-18 preamp aimed at about 186 degree magnetic compass. Here is how to aim antennas , http://www.kyes.com/antenna/pointing/pointing.html. The 2 groups of tv stations are 117 degrees apart , thats a real wide streach for a directional antenna to receive. The HD7000R antenna is aimed at KMCA channel 10 http://www.americaone.com that is a weak channel in between the 2 groups of stations. Here are places to buy antennas and etc. , http://www.solidsignal.com , http://www.amazon.com , http://www.starkelectronic.com , http://www.3starinc.com , http://www.winegarddirect.com , http://www.antennasdirect.com

That's the antenna I have. I rigged it to mount onto a mast.

Also I do not get that channel you asked about. I will try your recommendation thank you.

Install the HD7000R antenna and the PA-18 preamp , and the 4 way splitter. If KMCA is not received with 4 tv's connected then remove the 4 way splitter and install a Channelmaster CM3414 distribution amplifier. The CM3414 is not an automatic install , it is only installed if it needs to be.

Ok one last question I did the calculation for my db loss. With 75 ft of coax from antenna to splitter thus about -6db loss+ 4 way splitter is -7.5db loss plus roughly 140 ft of coax To the 4 tvs is -8db loss so I calculate approx -21.5 db loss. Is that the right pre amp to have? Thank you dimming for your help sir

The PA18 will overload in this location. Select the CPA19 instead.

There is no need for an all-channel antenna in this location unless you really want Daystar, the only programing that is unique to the low-VHF band in this area.

You'd do best to first investigate the fare available separately from the Chico or the Redding locations and determine of you want both or only one of those markets. Only then can an informed recommendation be made based on YOUR requirements.

I basically jus want to receive the basic network channels abc, PBS, CBS, fox etc which I already am with my current setup but not when I throw in the splitter. Fox 20.1 and 24.1 nb will glitch when I throw the splitter on. Here's my updated digital only tvfool map

http://www.tvfool.com/?option=com_wr...60b5b0ccaf855a

Basically just want everything from krcr-dt down to Kmca 50.1 I guess. I get most of those already without the splitter so should I just run a distribution amp?

The optimistic approach would be to install one antenna with a wide forward beam (such as the HD7000R) hoping to see both Redding and Chico. The CPA-19 is the better choice of preamp in your situation. Mileage ratings are less helpful than reasonably accurate gain figures... read through the forum threads for more thoughts and explanation re. mileage ratings. I believe the HD7000R and CPA-19 would be an improvement over the RS antenna but the extreme angle between the Chico and Redding transmitters worries me.

If that doesn't work well, you're faced with choosing from:

1) A larger (more directional) antenna on a rotator. This is often frustrating to anyone other than the viewer with control of the rotator. Many TV's will only display channels detected during a setup scan and will 'forget' the previous channels each time you re-scan. This can make using a rotator very frustrating.

2) Multiple antennas. This would require cabling each antenna separately to each TV. You can use an A/B switch at each set to select the desired antenna, but this will be problematic for sets that lack the ability to scan for or add additional channels.

3) Multiple antennas with an additional set-top-box tuner. SD tuners are fairly cheap. HD tuners cost a bit more... Channel Master and Pico Macom are a couple of examples of HD capable STBs. With one antenna feeding the existing TV tuner and the second antenna feeding the STB, the TV remote will usually let you select the HDMI or video input of the TV.

If I were in your situation, I'd go with a multiple antenna install. I'd point a Winegard HD7694P at about 245° and a another Winegard HD7694P pointed at about 130°. I'd mount the antennas separately, at least 8' apart. Again, the CPA-19 preamp would be a good choice for each antenna.
