Horizontal Loop Loading Methods
The primary radiating area of a half wave loop is about 1/8th wavelength. We are essentially end loading a 1/8th wave long dipole when we use a 40 meter full wave loop on 80 meters

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

23cm Yagi Antenna building Finished antenna at 1275 MHz SWR under 1:1.5 at resonant frequency
50 MHz preamp Gain 26dB with the BFG135 Preamps for 144 and 430 MHz, for 50 MHz, the BFG135a is a cheap transistor and in my view rather strong. It is not easily damaged by static discharge or RF power. FG connection
