I wonder what the size and cost of the Vacuum variable is to make a
similar antenna??

Hi Buck,

Take your cue from the page. Multiply by Q and you have your ratings
(add a safety factor). Go to eBay and look at the prices. Place
order and wait for the mail. Assemble. Operate.

I suspect you already know that and are seeking solutions that border
on fantasy. Art has revealed the characteristics of his 160M antenna
(it takes only scaling to your favorite band) to obtain remarkable
results (he knows what they are, but hasn't actually tested one).

Fantasy publication is common enough here to satisfy any taste: You
can get at least 3dB more "efficiency" (emphasis due to its new,
tailored definition). You enjoy new equilibriums not formerly
available in common and ordinary antennas (such as those drab and
outdated models found at the web page you provided). You can discover
added signal strength from Gaussian principles (it's not just about
gain anymore). Find the hidden power of polarization unknown to the
general antenna marketplace. Size is of no consequence with
counterwound coupling. Q is no longer the irritating limitation it
once was. Marvel at hiding it in a hula hoop in the grass so the
neighbors don't suspect it as an antenna. No RFI either! Mount it on
a steerable camera mount so you can point it (and the camera) into
neighbor's windows.

Advantages galore to be found that were previously unthinkable with
those huge and cumbersome antennas that could only communicate with
half the world.
