Plans to make an HD antenna are available on MikesTechBlog.com, TVAntennaPlans.com and LifeHacker.com. Some supplies required to construct an HD antenna include screws, washers, wire, wood and a balun. Tools needed include a drill with a screw bit, wire cutters and pliers.
The first step to making an HD antenna from the plans on TVAntennaPlans.com is to mark and measure the wood. In the next step, construct eight, 7-inch "Vs" out of the wire. Using the screws and washers, attach the "Vs" to the wood at the pre-measured and marked intervals. Lastly, attach the reflectors and the balun, ensuring the reflectors do not come into contact with the wires.
