With an outdoor antenna you can watch HDTV for free of cost. All you need is a high definition television or an HDTV-ready television.

For this purpose it is better to install your antenna in the roof of your house.
Some of the tools and the accessories that you need to install the HDTV antenna in your roof and then to connect it to the HDTV or the high-def tuners are, Mounting hardware, wrench, drill, screwdriver, grounding wire (the length should be sufficient to run from the antenna to the ground), grounding strap, coax grounding block, and a shielded 72 ohm coaxial cable (all weather). The length of the coaxial cable will depend on the distance from the antenna and the place where you have your HDTV or the high-def tuner.
