A company in Florida once dazzled the Army back in the ‘70’s or 80’s with a compact 2-30 MHz dipole targeting the Manpack market as I recall. They made a similar claim... Something like 1.5:1 SWR over the entire range.

  It didn’t take a lot of effort to reverse engineer the design... essentially a short dipole as advertised, shunted at the feed point with a 50 ohm power dissipating resistor. i.e. a leaky dummy load of sorts. Indeed... no tuner required. Don’t you just love the creativity of marketing?   Truth in advertising at its best. LOL!

Tom sez:  The "MAXCOM automatic antenna matcher". And they sold millions of them to thegovernment, who wanted "no tune" antennas for Embassies, MARS and the military. They received OK, but most of your trasnsmit RF went up in heat!
