New TV Antenna
This past Monday had me at my parent’s house again, in Waterford. My parents don’t watch a lot of TV and they do not want to pay monthly fees for DirecTV or DISH Network. As they live out in the country, where there is no cable television, their only hope to get local TV is the traditional way… put up an antenna. They are greater than 60 miles from either the Sacramento television stations or the Fresno television stations, so we need a good antenna. I did quite a bit of research prior to Monday and had purchased many things needed for the job. Other than the over-the-air (OTA) antenna, my parents also have an Adventist Satellite system that gives them channels such as The Hope Channel, 3ABN and Loma Linda Broadcasting Network; religious programming. My job was to make it easy to watch these channels and local news.
First off, the antenna; my father purchased a Radio Shack VU-190XR VHF/UHF 160″ boom antenna. During my research, I argued debated with a local TV installer about what I needed. He insisted that using a smaller antenna and the strongest powered amplifier was the way to go. I felt that having a better antenna was better. I view it much the same way I view digital cameras: optical zoom is better than digital zoom… in both cases, you can only boost what you truly have. If you amplify a very poor “iffy” signal… you will have a stronger “iffy” signal. If you digitally zoom a wide shot, you are only magnifying the details you already have. Anyway, I felt the larger antenna important. I also wanted to install a rotator, especially since a bigger antenna is more directional than a smaller one. I chose the Channel Master 9521A digitally controlled rotator, as it is both strong, simple to use and pre-sets can be set. Since I had previously had a pull-string in a wall, it was easy for me to run the rotator control cable. I had also previously placed coax cable for the purpose of an OTA antenna and ran both out a vent, onto the roof of the house. I chose a mount with guy wires for stability. I placed the antenna mount about 10 feet from the west edge of the roof, at the peak. I placed eyebolts low on the eaves of the northwest and southwest corners, as well as about 10 feet east of the antenna mount. Securing the guy wires was probably the most difficult part of the job. For the lower mast, we used a 1″ galvanized pipe with an outside diameter just over 1.25″… the “just over” bit was an issue, as the mounting hardware was designed for a 1.25″ outside diameter. We had to modify the guy wire ring to get it to fit over the pipe. I believe we made that pipe 7-feet long. We had no issue placing the rotator on the pipe. The antenna was thankfully easy for me to install; lucky for me being over 6 foot tall. Since my parent’s house is a two-story house at the top of a hill and the tallest thing in the area, I was worried that it would be at risk for lightning and static electricity build-up, so I wanted to ground it well. We purchased an 8-foot copper-clad steel grounding rod and rammed it 7+ feet in the ground. We ran 6-gauge bare copper wire from the antenna, down a guy wire, and down to the northwest corner of the house, where I pounded in the grounding rod. The wind really picked up about the time we finished the job and I was happy to note that the antenna did not move much at all, despite the wind. My biggest worry with the install is the 3rd eyebolt installed on the roof… I’m worried that it may have too much pull against the threads. I’m thinking that replacing the wood-screw type eyebolt with a machine eyebolt with a big fat washer and nut on either side of the roof sheathing. I think that would relieve my worry that it may pull out.
Once everything on the roof was installed and grounded, I turned my attention to inside. I had purchased a ChannelPlus DA-550BID distribution amplifier, which makes up for loss in signal through the wires. The amplifier also mixes in RF modulator signals. An RF modulator takes a (usually) composite video signal with audio from a device like a satellite receiver or DVD player and outputs it onto a channel that can be tuned in by a television. I also purchased a ChannelPlus 5545 4-channel RF modulator, which allows for up to 4 devices to be inserted onto blank UHF channels. After hooking up a television to a jack, I scanned the channels to see what I could find. I had aimed the rotator towards Sacramento and pulled in all of the Sacramento channels perfectly. I then rotated the antenna towards Fresno and pulled in all the Fresno stations perfectly too, in addition to channels from Visalia and Merced. I then connected two satellite receivers to output on channels 28 and 36. Everything works exactly as I had hoped. I was quite relieved.
My parents are now looking to purchase a new TV, they currently only have a borrowed television. At this time, it appears that they will be going for a 32″ LCD TV. One of the nice features about these televisions are they include an ATSC digital tuner, opening up more channels my parents will be able to receive. Two examples of additional channels are KCRA broadcasts a sub-channel of NBC Weather Plus or KXTV’s AccuWx TV weather channels. Other sub-channels include The Worship Channel, ION, ION Life, and qubo. While the initial investment is inevitable, at least there are no subscription fees.
