Digital TV Coat Hanger Antenna
Rabbit ears are for rabbits, not digital televisions. In this project, we’ll show you how to build your own digital TV antenna from wire hangers, a piece of wood andsome pipe.
Television antennas are comprised of a series of metal rods cut to exact lengths and positioned so they receive a particular television frequency. The following design was invented in the1960s by an engineer named Doyt Hoverman. It is particularly sensitive in the UHF frequency range, the same range used for the majority of digital television transmissions.
Tools
Electric drillScrewdriver or screw shooter Screwdriver bits 1/16” drill bit 3/32” drill bit ¼” drill bit Scrap wood
Materials
Wire hangers (6) Wood board, approximately 3” x 20” x ¾“ #6 round head wood scews,¾” long, and washers (10) U-bolts, ¼” diameter, 2 ½” long, nuts washers (2) ¾” diameter iron pipe, 24” long, one end threaded ¾” pipe floor flange #10 wood screws, flat headed, 1” long (4) Wood board,approximately 12” x 10” x ¾” 75 to 300 ohm matching transformer with spade clips on one end and female F connector on other
Estimated Cost:
$20 or less.
Before you begin:
You may find itnecessary to modify these instructions, depending on what materials and tools you have at hand, and any improvements you might want to make in the design. Go ahead and customize the project and make ityour own!
