I have seen this before and still have to wonder if it is not trying to profit from the gullible. I mean seriously, the 10m seven element yagi is $877,half of what they are asking for the six element 11m model. Face it a lot of CB'ers are gullible when it comes to the power ratings of what they think their amps are actually delivering versus what the DC power draw on them are and also as to some of the wild gain figures some antenna manufacturers make, so perhaps M2, who really makes the antenna, sees an opportunity to take advantage of that just like some audiophools (audiophiles) believe that you have to spend several dollars per foot for speaker cable because it makes sooooo much difference over regular zip cord.In short there will always be those that believe everything they see or hear and without fail there will always be those quite willing to sell them what they think they need at a price they think it is worth.
