In the october issue of "QST" a new Cushcraft beam generation
can be seen. Unfortunately, many of high interest data are not
shown ( like gain and front/back ratio ).
For those without browsing capabilities, I'm posting here more
tech specs as figured in their home page.
No details are given on the 2-el for 40m option ( dimmensions
after upgrade or performance ).
For any possible censor: be sure I'm not related to Cushcraft, I
only try to help those subscribers with only e-mail services.
