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

40 meter 10 mt delta loop
This simple broadband antenna is easy to build,has gain similar to that of a dipole and is tolerant of near by objects
70mHz 4 metre Delta Loop
Although I would only have FM on 70mHz I thought that making another horizontally polarised Delta Loop made sense for a number of reasons, first it was simpler to mount and secondly it would give me chance to see if nesting the loops caused any problems
