well https://www.amazon.com/NooElec-Balun-One-Nine-Applications/dp/B00R09WHT6 and then, I have some v2, they work a bit better than v1, the other option is to pick a binocular core and wind the balun as for the v2, check the download section here https://www.nooelec.com/store/balun-one-nine-v2-bareb...

well, given signal reflections inside and all factors, the nulling seems promising; as for the balun... SIGH, but then it's a lesson I learned myself as well, ALWAYS use terminal blocks (if not using nuts and bolts) since they'll get the strain and not the balun, also, to lock the wires, a pair if n...

good !! I can't wait to read about the real world test !

as for the LoG, just put together a NEC model, place the wire at 1cm or so from ground, so NEC won't complain and see what comes out

a crazy thought (maybe), I wonder if using the same approach, that is resistor and balun at the opposite corners, it may be possible to make the LoG directional; I'll need to run some NEC simulations to check the idea...

My first SWL radio was a kit radio from back in the day. I have many great memories from building it with my Dad to the many days/nights of listening. I still use it from time to time...will never give it up. Does anyone still listen using a kit or home brew radio? not using a kit radio, but built ...

Yeah, another thing I forgot to buy is the alternative to that - a nice pair of M4 bolts and nuts/wing nuts/washers to use cable lugs, making that all as "modular" as it gets. BTW, the balun and the preamp weigh like 20 grams together and I'm planning to omit the preamp first, as long as ...

Yeah I understood this, it's just that I'm usually reluctant to bend coax sharply, even the double foil-shielded stuff, particularly that stiff Belden H-155. Probably unnecessary in this case since that's being bent only once and at the antenna where the integrity of the shield isn't that important...

quick note, will reply more extensively later; if you're using the NooElec v1, ensure to cut the "R1" trace to achieve full galvanic isolation ! https://www.nooelec.com/store/downloads/dl/file/id/40/product/192/balun_one_nine_schematic.jpg in short, the V1 has a tapped transformer, antenna...

Ah yes, of course - the inside of the loop is probably less prone to be disturbing the pattern and that would indeed solve the problem with the load and the preamp, that could sit just inline with the balun box, at the feed line end equipped with this: no need for the angular adapter, see this sdl_...

As a note, the difference between a 530 Ohm or a 540 Ohm load resistor is negligible, so 2x270 Ohm resistors in series will just fit I figured. I'll have to use 2x 1kOhm parallel -> 2x 47Ohms parallel for 523 Ohms (the 525pc resistor box doesn't come with 270 Ohms). With some good layered shrink tu...
