Antenna Loop reception 80m and 160m
Experimenting with loops and found them to be very good Rx antennas. They have a useful null and provide a wonderfull drop in noise to bring the DX in

Transmitting loop for 7 MHz
Large-diameter plastic support frame surrounded by thin layer of copper
A Stealthy 75 meter Antenna
The 75 meter dipole was put up to meet the need for making contacts with friends in the Southwest and Southern California to be put up so no one can see it from the surrounding neighborhood
A Stealthy HF Coat Hanger Antenna
You're looking at a 110 foot inverted-V, fed with homebrew ladder line
Antennas for Limited Spaces
Some problems that while not unique to Florida are certainly more pronounced here Lots tend to be small, often less than 2000 square feet.
