Portable HF Delta Loop
A delta loop antenna is described which is cheap, simple to make as well as being very quick and straight forward to put up for portable work. With a balanced ATU it will work well on 20, 15 and 10m
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
Delta loop 50 Mhz
A Delta loop is formed by an equilateral triangle, the base of which can lie on both the top and bottom and can be hung on various shapes

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
