Just had an idea; what about transforming one of those "chinese loop antennas" like the MLA-30, into a cardioid loop ? Mine is down the basement, so it will take some time to put it back on duty, but if someone here had an MLA at hand, I think it may be an interesting experiment; it would ...

NICE

which kind of loop is the one hanging on the wall ?

also (I'm curious) which antenna is connected to that coax going out, through the window frame ?

Here's a video I shot last year using the passive 20m LoG antenna before I shot the pics above: [...] That's 16,000km away from my secret LOG testing ground, on a day with no particularly elevated condx. The link seems to be working, and the video shows what an antenna laying on ground can do; then...

I've used a W6LVP loop in the past and was very pleased with the performance. Attached is a photo of it (from a few years ago) in the shack installed on a tripod with an RCA rotor. Eventually I moved the antenna outdoors for even better reception. It's an active antenna with a preamp. Don't know wh...

working ok for me !

Oh and, as for "matching", if you feel you need such a thing, you may just pick an MFJ-956 , it won't break the bank and will serve you honestly well, plus, if you'll then decide you'll need a preamp, you may pick up whatever wideband LNA and place it between the MFJ-956 and the receiver s...

Like the typical home, mine has its share of RFI. That's one reason the loosely-wound helical vertical was interesting, because the noise floor was lower. (But to make that antenna permanent, I need a dedicated broomstick, not the actual household broom!) I have taken the Belka outdoors on several ...

A reel up won't work like a loop, what I was suggesting is to tape a wire rectangle inside the window glass at some inches from the window frame (if it's a metal one), connect the ends of the resulting rectangular loop to a balun and from there run the coax to the receiver, willing to turn that ant...

As a note, the "belka" isn't so picky about impedance (and a lot of oldtime rigs won't present 50 Ohms as their input impedance), no, the issue (if we want to call it so) is mainly about input levels; start by setting the antenna gain to min if you aren't using the stock whip, and, when it...
