Question DetailsAsked on 9/21/2011

I can't find a category for a man to maintain my roof antenna for broadcat TV (not cable). The man who put it up has left the state.

The person would have to know how to tune the antenna for different stations (especially Canadian public TV which has just gone digital and changed channels). He would have to know how to connect two more TV sets to the antenna. He would have to know when the antenna wasn't working right and what to do to fix it, as after a storm, etc. These men have to exist because they work for cable companies that have roof antennas or receivers. Many people have broadcast roof antennas rather than cable. What do they do?
I live in Ferndale Michigan. I can get 18 broadcast "air" channels with my roof antenna now.

You might try local ham radio club and see if a member would be interested in helping you,, They are experts at tuning their antnnas so potential is there, Or a dish installer, You could ask local dish dealer for installers phone # and give them a try, both of these could address your wiring issue.

Have you tried checking the "TV Antenna" category on Angie's List? www.AngiesList.com

Roof antennas used to pick up local broadcast stations are directional - so depending on where your local stations and their repeaters are located, it is common to find that you can pick up most local stations regardless of antenna aiming, but to pick up the ones from further away or who do not have local repeaters to cover the whole area you have to pick and choose which you want to view.

Aiming of the antenna just involves slightly loosening the clamp on the antenna enough to be able to rotate it without it sliding down the mast, then turning it while another person is keeping track of which stations come in at each setting - most digital tuners and add-on digital tuning boxes have a signal strength indicator on one of the setup option settings so you can see where it has the strongest signal. Easiest thing is to draw a 360 degree map showing, with partial rings around the center point for each station, where each station comes in acceptably as the antenna is rotated in about 10 degree increments, then decide which direction picks up the most stations that you want.

For the ones you can't get that way, or maybe to eliminate the antenna entirely, there are electronic antenna boxes for about $25-50 you just put on a shelf near your TV (except in buildings that are metal sided, steel framed, or have foil facing on their insulation, in which case they may work only near a window) - in our case such a Magnavox antenna located in the basement worked better for ALL stations than an existing 10 foot long antenna 26 feet in the air. The beauty of it is, with a splitter switch box you can use both antennas, though you have to punch a button on the splitter switch to change from antenna to antenna. Many times you can actually have both connected together and not have to swtich back and forth, though sometimes having both connected at the same time causes a fuzzy image. A LOT cheaper than an antenna with a power rotator, which typically only last maybe 5 years at most unless you buy a very pricey commercial antenna one, if it will work for you in your area. In areas of very weak signal strength, you are stuck with an antenna.

As for maintenance - not much can go wroong with an antenna - if the connections have gold plated contacts put together with dielectric silicone in them and are then sealed with heat shrink tubing (if outdoors or in attic) they last almost forever, and are pretty easy to replace yourself if one does go bad. Otherwise, unless a storm takes your antenna down (not hard to replace yourself if you are not afraid of roofs or ladders), there is no real maintenance.

For two or more TV sets, unless you have very long runs in a long house, you can just use an antenna splitter block (a few bucks at an electronics department) to divide the cable where needed to several separate runs as needed. The antenna and cable are carrying all the signals together without discrimination - the splitting out of the different frequencies to find a specific station occurs in the digital converter box or in the TV tuner, so one antenna and coaxial cables to the different TV's can serve several TV's at once, which can all watch whatever broadcast station they want at the same time. With digital TV conversion, each TV WILL need a separate analog to digital converter box or digital receiver box - typically about $25-40 each. Your TV station websites and probably Communications Canada website, and lost of US websites, have instructions on how to put in a converter box for an analog (old TV. A new digital signal TV does not need any converter box at all to handle digital signals, but does need a different kind of converter box to convert analog to digital if there are still analog stations in your area you want to watch.
