I want to install OTA TV antenna
 
I apologize up front if this question has been asked and answered before.

I was pleasantly surprised when I learned that the FCC overrules most, if not all HOA bans on outside roof antennae. This is great news for me.
I have cut the cord on my cable for almost a year now. I had fiber internet installed for streaming and went from paying over $250 per month to just $80 for a 1000mb fiber account.
My issue now is with OTA broadcasts of local channels. I have those “paper-thin, leaf-like” antennae in different rooms connected to each TV. The problem is reception is lousy on one side of my house compared to the other. So, I thought about installing a larger centralized antenna system either in my attic or on the roof. Here is where it gets confusing for me. I’ve watched a few YouTube vids that explain connecting the antenna to a media box or junction box usually located in the basement and utilizing the existing coaxial cable system run throughout the house.
Because I live in the South Eastern part of the US, I don’t have a basement. All I have is a box on the side of the house that was used to split my cable signals to each room in my house. Is this the same thing? If I utilize the existing coax, will I need a signal booster from the antennae to ensure strong signals to each TV? Thanks y’all 😉!

Yes it is the same thing. However depending on what service you had may or may not have the correct splitter in the box. For example if you had a satellite dish before, the coax can be reused, but the "splitter" will not work for OTA signals and will need to be changed.

You might be able to use just a passive splitter which is going to be the least expensive like one like this: https://smile.amazon.com/PREMIUM-Spl...+coax+splitter .
That one is a 6 way, but we would need to know how many rooms you need to hook up to recommend a specific one.

Depending on your location and thus your signal strengths, you may need to use an signal amplifier at the antenna or a distribution amplifier instead of a multi-output splitter. To know we would need your www.tvfool.com report. Go to that site (http://www.tvfool.com/index.php?opti...pper&Itemid=29) and enter your address to get the report. Then post back the URL for us. Since you don't have enough posts to post a link, just post the part of the URL after the "http://www.tvfool.com/" which should start with "?option=" so we can get the data.

Antenna amplifier:
https://smile.amazon.com/Channel-Mas...enna+amplifier
This amplifier mounts on the mast at the antenna and the power is feed through the coax with an indoor power supply which is in the antenna coax. You would need to supply 120vac to the power supply, so if there is not any ac power in the existing box, you may need additional equipment to get power to the antenna power supply.


Distribution amplifier:
https://smile.amazon.com/Channel-Mas...enna+amplifier
That is a 4 port, they also make an 8 port:

What is nice about these are they have the power feed by a coax cable which will allow you to use an existing coax run into the house to supply power to the amplifier.


Those are just some general equipment suggestions which we can refine when you give us your tvfool data. Also an antenna suggestion can be made with the data.

Finally, WELCOME TO THE FORUM !!

Thank you so much for your support. Here is the data from TVFool:

Thanks, again.

rbinck doesn't seem to be available now. Is this your report?
http://www.tvfool.com/?option=com_wr...9038ea2e572f91

Will you be using the existing coax cables only for antenna reception with a separate connection for internet, or do you expect to use the existing coax cables for antenna reception and internet?

rbinck 05-31-2018 08:02 PM

Go ahead rabbit.

bimfi 05-31-2018 10:47 PM

Yes, the existing coax will only be used for antenna reception. The internet is brought in through dedicated fiber line to Ethernet router and WiFi.

Your TVFool report does not show WCSC CBS because they are using a defective database to generate reports, but it does show on a report from rabbitears.info:

https://www.highdefforum.com/attachm...dfreportre.jpg

Most of your channels are on UHF (real channels 14-51), but WITV PBS is on VHF-High (real channels 7-13), so you will need a UHF/VHF combo antenna like the Winegard HD7694P. Try it in the attic first.

Interestingly, WITV will be moving to UHF channel 24 in phase 10 of the FCC UHF Repack:
https://www.rabbitears.info/market.p...&callsign=witv

These are the changes in your area:

You will need to rescan your tuner.

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.

Since your signals are strong, check the reception with just one TV. Next add a splitter. If the signals are too weak after splitting, add a single output distribution amp like the Channel Master 3410 before the splitter, or replace the splitter with a distribution amp with more than one output like the 3414 which has 4 outputs.

If the signals are still too weak because of attic loss, you will need a preamp at the antenna, and its power inserter down below, followed by the splitter.

The last resort would be to mount the antenna outside, but I don't think you will need to do that unless there is a signal loss I'm not aware of.

My plan is, or was, to set up an antenna in my attic. I'm not too keen on climbing on top of my two story roof, especially at my age. If I must do so, I will probably hire someone to do this. Anyway, will the length of coax needed to go from the antenna to the outside box degrade the signal, or will the pre-amp or amp fix this problem?

I'm thinking that I either place the antenna on the roof or in the attic, then run the cable into the attic and have all the connections and power necessary in one place. Then run the coax to the end of the house and drop it down the outside of the house to the cable box.

Try the attic first; it has a good chance of working. Do you have a TV with a signal strength indicator that well let you know how weak a signal can be but still be received?

Yes there will be a signal loss in the coax to the box, but your signals are quite strong. A preamp at the antenna would make the signals stronger BEFORE the coax loss, but it would need to have power before the splitter, or have a special power passing splitter which is a complication unless you have AC power in the attic.

That has a good chance of working with an attic antenna.

If you have a problem, come back here to this same thread.
