Delta loop 10-80m
We actually wanted to build a similar antenna on 80 and 40m and we were pleasantly surprised. It works even on higher bands Its principle and mechanical construction is exactly the same

Vertical Loop for 80-6 Meters
loop antennas have always fasci nated me. From a common sensestandpoint they seem impossible.I mean, how can you have a short circuitat the output of your transceiver
Yet another delta loop antenna
I decided to try a loop antenna and I only had one mounting point on the paneling, so I used tape to make a triangle, but if I used an equilateral triangle as in all of the antenna books, I would have to put a nail in the middle of the paneling
Delta loop rotable for 40 m
the delta loop has an impedance of about 100-120 ohms. a quarter wave of 75 ohm coax is used to transform the impedance down closer to 50 ohms

Linear loaded short dipole 21Mhz For my amateur radio activities on the HF bands I only have a 3.6 m wide balcony available for antennas. After some study I decided to experiment with a shortened dipole for the 15 m band
