New SW antenna on Universal's online catalog.

The inventor of this antenna makes some wild claims about some of his other antennas, which I own and they do not match his claims. He seems to sell himself as a Phd in electronics/antenna theory but he's actually a low level medical doctor of some kind. That might explain why he only has a tech class ham license.

I'd like to see the coax common mode choked please. Hard to do on that magmount at the feedpoint unless you hack it.
I get PLENTY of signal from my loop wires that are entirely on the ground. Choke that thing.
Unless one wants to listen to near-field magnetic components that are less than 1/20th wavelength away, anything beyond your backyard is definitely far field, and no matter the antenna, it is the E field, not the magnetic that drives it.
Be very careful here. Anyone remember the E-H antenna. Uh huh.
A dangerous topic, as 20 years of usenet bickering about "shielded loops" responding to the magnetic field turned out to be false for anything worth listening to beyond your shack.
I'm still open to it, but "proprietary" antenna engineering kinda raises my inner skeptic.
Some pretty unflattering words for Doctor Jack. How well do you know Jack?
I met him 30 years ago when he attended the ham radio class I was teaching and passed. And has done well with his life.
So, you don't like his antennas. Just say that and be done with it.

Actually have the 145/220/440 MHz mobile antenna. It works as good as any Larsen dual band I've ever had, and any other branded antenna/antennas.
But, would I buy that for shortwave, most likely not. I prefer something that would be a 'bit' bigger.

Bravo, thinking critically can guide you toward a favorable result. A bit of wire outdoors, a proper balun, coax/feedline and a passive tuner can provide happiness on RX. (One may quickly learn that AM and or FM band filters inline can prove quite helpful.)Think I will save my $$ and work on building a hidden exterior dipole for 6 meters.
