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...

Ok, I think we may stick with "SDL" (Small Directional Loop) or "SDRL" (R for Receiving) I suggest SLOB then, you know it really helps if the acronym is a word (took me 2 years until I could memorize "NCPL" and 10 for "G5RV/HB9CV/W3DZZ"), or the antenna has a...

As a thought, the "SDL" may be built using off-the-shelf stuff, a spool of wire, some resistors , some PVC pipes, a NooElec 9:1 v2 balun , some snap-on ferrites and optionally a NooElec LANA HF (or a similar low noise preamp) will suffice to put together the antenna; add two or three (if u...

Hmm... I have no experience with naming antennas other than giving mine the "crap" prefix, craploop, crap-pole...because I initially thought they are cheap and simple so they must be crap :mrgreen: Crapbeam sounds not very attractive. The Greyhat SLB (Small Loop Beam) Small Unidirectional...

Just for fun, if the antenna stands to the "real world test", I think we'll need to find it a name, now, I was thinking to something short and easy to remember and following the acronym "tradition" (LoG, SRL, NCPL, ...) I think that this one may be called SSB (Small SWL Beam), bu...
