[TowerTalk] Maxcomm and B&W folded dipoles

[W7RY]

That QST review of the Maxcomm is quit interesting!  I'm sure that kind
of thing is more prevalent today than 1983.

Thanks for passing along the info.

The Maxcom was reviewed (debunked?) in QST, November 1984.  The product
review is available in the members-only section of the ARRL web site. 
There are X-ray photos as well as one of a unit with some of the
potting cut away.  The circuit board components weren't even connected
to anything (I don't recall if the article mentioned whether or not the
toroid was connected.) It apparently is just a bunch of resistors
across the input (the VSWR was < 1.4:1 across the HF bands with no
antenna attached!)

QST reviewed one of the B&W dipoles in March, 1981.
