Antenna Multiband delta loop
A multiband antenna, giving comparable results to a mono-band loop or dipole. At the open end of the loop a 1/4 wave shorted stub for 28Mhz was added. The stub and the feed line is made of 450 ohm ladder line. The stub opens the loop on 28Mhz, on all other frequencies the antenna is working as a closed loop

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

50MHz to 28MHz RX Converter The concept of the rx converter is quite simple and nothing really new. the local oscillator is a standard colpitts crystal oscillator producing the 22mhz lo signal
