While you're at it look up Hy-Gain

Then look up the designer of the Hy-Gain AV series and the Cushcraft R series. There is a reason they look so much alike. But why did Cushcraft keep a couple traps? Just to make it look different? Reduce efficiency just to look different?

It's like trying to find the same applications in Win 10 that were in Win 7. They just reorganized it to look different? You really need to hunt to find some of that stuff.

It's basically the same speed with more annoying adds and programs that phone home.

Didn't you know that Cushcraft had been sold, long ago?
Compare the address in that ad you mentioned with the address of MFJ. (see page 127, same issue)

First there was the Gotham Vertical. Then the infamous Max-Com automatic antenna matcher. Now, Cushrcaft is in on the action.

"R9"
vertical.  Low angle radiation gives incredible, easy, world-wide low
band DX on 75/80m and 40m, plus it covers 30 through 6m with low
VSWR on all bands, with broadband matching transformer; no antenna tuner
needed. Low profile blends inconspicuously to keep your HOA happy.  31.5
ft tall.  Best of all, NO RADIALS NEEDED!!!

Only $639. Just plug in your plastic radio and talk, talk, talk!

See November, 2015 QST, page 2.

Amazing
that hams (or maybe I should say HAMs) swallow that crapola.  31.5 ft
is only an eighth wavelength on 75/80m. The base impedance of a 1/8
wavelength vertical is about 12 ohms. No matter how much gimmickry such
as stubs, loading coils, toroidal transformers and porcupine spikes are
added, that thing will basically be a dummy load unless it is used with a
SUBSTANTAL radial ground system.  A couple of 8' ground rods won't cut
it.

I had always considered Cushcraft, which has been in the business for decades, a reputable outfit, but this makes me wonder.
