Home Brew -VK2AWJ LOOP 80, 40, 30 and 20m
John sent some early photos of the Loop and tuning unit. Note - the LCD
capacitor position indicator board has not yet been fitted in this picture.
There is no dramatic difference in performance of the loop compared to the Bushcomm dipole, the latter being a 'Quieter' antenna when listening. Signal reports suggest similar signal strength when transmitting. I have not had time to explore the advantage of the directional ability of the loop"
I have made no provision for ground plane radials, only running an earth lead from the antenna socket to an earth stake.
The gamma match is working very well with SWR =< 1.2 on the 80, 40, 30 and 20 m bands I can tune.

Johns home brew 5.52m circumference loop using
25mm copper tube. John built his loop controller and
LCD loop position readout based on my design.
