Simple Ham Radio Antennas: Full-Wave Loop Antenna. Post #368.

Nice, easy to understand tutorial on Full-Wave Loops antennas from Stan Gibilisco (W1GV). I've used full-wave loop antennas for many years and have found them to be simple, effective, and efficient. Full 80-10 meter coverage can be gained if you design your full-wave loop for 80 meters and use 450 ohm ladder line as your feed line . The ladder line then goes into a balanced tuner , which is connected to your rig by a short length of coaxial cable . If you don't have a balanced tuner, you can connect the ladder line to a 4:1 balun and use a short piece of coaxial cable to connect the balun to your tuner. You can use a variety of shapes for your full-wave loop, with the square and delta loop being popular options. For the latest Amateur Radio news and events, please check out the blog sidebars.

Simple Ham Radio Antennas: Stealth Amateur Radio Antenna System (7 MHz to 1.3 GHz) AKA HDTV antenna. Post #302.

Here's a curious design for a stealth antenna from Jim Whitaker . The antenna appears to be a type of Off Center Fed Dipole ( OFCD ) capable of working on 40, 20, 15, 10, 6 meters . The antenna functions as a discone for 6 meters, 2 meters, and 70 cm. I've built a few OFCD antennas , but they didn't look like Jim's. You may want to test Jim's idea if your antenna space is limited or discouraged by HOAs and CC&Rs.For the latest Amateur Radio News and Events, please check the blog sidebars.
