Topband: NEW BEV DESIGN?

[Mike Greenway]

There is new player on the low band receive antenna market that will be at Dayton.  Here is the link

I have looked at their brochure but have one big question.  They say the feed point, which has two coaxes, can be put at any point on the wire.  If I put the feed point at one exteme end, that gives me a bi directional receive antenna with one wire?  I have used two wire systems and understand the need for the second wire there, but not sure I see the theory behind two directions from one wire fed on one extreme end.  I have seen designs that do feed at different points along the line and could see if the feed was put near center you could get two directions, but it would seem the closer to get the feed to one end, one direction is going to suffer due to shorter wire length.   I understand they will be at booth BA 0488 on Saturday.  See some of you at the Topband dinner on Friday night.  73 Mike K4PI
