[TowerTalk] M2 40 meter Yagi

[kdutson at sbcglobal.net]

I have the 40M4LLDD model.  It has four elements and covers 7.0-7.3 MHz.  SWR is below 2.0 across the entire band.  This is possible because it has two phased driver elements, one for each segment of the band.  So, you end up with two three-element Yogis.  This is a great antenna for $2929.95, as seen on the M2 web site.

The 40M4CDD model covers less bandwidth with lower price $2729.95, but promises flatter response.  The selling point is that one does not need the frequencies above 7.2 since the foreign broadcasters have moved to other frequencies, and European hams can now use 7.0-7.2 phone and cw.

If I were the manufacturer, you would not see me publishing a graph like you want.  There are too many installations that are far removed from what the manufacturer can do to produce the graph.

M2 has a new version of their 40 meter Yagi - 40M4CDD.  unlike the one it replaced, it covers 7.0 - 7.2 mHz, or 7.1- 7.3 mHz.  Of course the "adjustable" elements can be shortened to make the sweet spot  up a little higher than 7.0 - 7.2.
The brochure says SWR varies from 1.2- 2.0.  However, when I asked M2 if they could send me a print out of the graph they responded they couldn't, which made me scratch my head.  $3000 for an antenna and they can't do that?
Anyone out there who has this specific antenna, not the one it replaced, let me know your experience with it...SWR, construction etc.
