This is Post #1031 in a continuing series on "Simple Ham Radio Antennas." This is another great, easy-to-understand antenna tutorial from "Ray" of the "Radio Workshop." If you can only erect one antenna to cover the 80 through 10 meter amateur radio bands, then the classic "doublet" antenna is your best best to get reasonable multiband HF performance at a modest cost. As Ray explains, a "doublet" cut for 3.500 MHz (total length of 133.71 feet/40.76 meters) will perform well on amateur radio frequencies between 3.500 MHz through 29.999 MHz if you feed the dipole antenna with balanced line (300 ohm television twin lead, 450 ohm ladder line , or homebrewed 600 ohm balance line). Run the balanced feed line into a 4:1 current balun and connect the balun to your antenna tran
