I keep on and on about my little balcony and the antenna restrictions it imposes on my HF antennas. This projects was developed as a result of experiments to become QRV on 80 meters, again, using the little balcony. I have now built several of these antennas with equal success every time. The frame antenna may not be the most efficient but it can get you QRV on 80 and is ideal for boats and holidays. The VSWR is almost 1:1 from 3.5 to 3.8 MHz. The antenna may be modified for 1.8 MHz but the efficiency may suffer.
