Does anyone have any experience getting a exterior HD antenna installed? I want to get one installed, but don't want the cable ran on the outside of the building stapled to the side. Should I bother when I live so close to Madison? I can get most channels except FOX.
Perfect timing, d0nkeyq0ng! If Fox 47 is the only station that's giving you problems, all that you need to do is wait until the end of the month for their new and improved ATSC UHF antenna to come online.
If you already have an exterior antenna, you don't need a new one.
Every TV antenna is a "HD" antenna. Don't let an unscrupulous retailer or under-educated big box store salesperson steer you into something that you don't need. Even old TV antennas work with the new ATSC HD format.
If you have an internal antenna, and the patience to wait until October 28-29, just sit tight and watch the WMSN-TV website (or here!) for news of when the new transmitter is up and running.
There are lots of good reasons not to use staples to secure antenna cable to your house, from the possibility for poor reception, to fire hazards if lightning should strike. If you're running 300 Ohm balanced line from the antenna (not very common these days) the use of approved standoffs to keep the line electrically isolated from your roof and walls is a must. If you're using the more common coaxial cable (RG-6 is best) you should ask your local building supply company what to use, so that you adhere to local building and electric codes, and don't jeopardize your homeowner's insurance.
Another option if you have an attic is to install an external antenna in the attic, beneath the roof. It works fairly well in good weather, and by keeping the antenna out of winter weather and wind, it might give you a better signal overall.
