Dear John, LF, I would like especially to comment on using a one winding loop combined with a step-up transformer: I am using such a loop for years with continuing success. The primary of the transfo
Ha-Jo, That's one way to look at it, and a valid approach. But consider another example: Suppose you have a single-turn loop that has an (arbitrary) impedance of 0.1 +j10 ohms at a frequency of inter
I would like especially to comment on using a one winding loop combined with a step-up transformer: I am interested in knowing opinions about using the loop itself as a primary of the transformer, as
Laurence, What do you think is the upper power limit for a loop using coaxial cable as a conductor? I've run about 1.3 kW into my loop made up of one turn RG-11 and one turn RG-214 (both turns parall
Dear John, I am sorry, but I do not see your problems. I do NOT tune my loop. The loop is feeding a transformer, its secondary is connected to a cable into the shack to the receiver or the preselecto
Hello John, Regarding the single turn versus multiple turn loop, I have done both. For the multiple turn loop, 100 meter of 1.2 mm PCV clad electrical mains wire was wound on a wooden frame with side
Use a vertical and avoid all the specified LOOP problems and directional limitations. Loops maybe for RX but for TX vertical systems, ie inv L, T top is probably the best approach on LF and MF. One w
Dear LF Group, Since I have used several designs of loop antennas almost exclusively for 136k and 500k reception, here are some thoughts:- For small VLF - MF RX loops, the available signal power from
Just to add a little more information on LF transmitting loops: Paralleling conductors is usually more effective than creating a multi-turn loop. The extra copper loss from another turn can easily ne
Ha-Jo, I wasn't making a comment on your setup -- just pointing out some options for others who might want a tuned, single turn loop. No offense intended! John, W1TAG I am sorry, but I do not see you
