[QUOTE="tballister, post: 45688, member: 5087"][b]Let's Be Careful[/b] Still feels to me that we really ought to remain cautious about the CM4228HD VHF observations. Just doesn't' feel like anyone here has yet offered any deep and credible analysis of the physics and mechanisms of the design that could contribute to such VHF performance. Unsubstantiated remarks like "it has [I]better [/I]nuts and bolts" really don't contribute to credibility. I'd love to see someone provide the deep analysis that can explain [I]why [/I]the nuts and bolts might be better. For example, there have been comments about the continuous versus split reflector, and let's be clear its role is [I]reflection[/I]. None of the energy landing on it goes [I]directly [/I]to the transmission line. The reflected energy must be captured by the active element(s) and [I]additive[/I]. I mean, [I]is[/I] the reflector the main reason for the VHF performance? If so, [I]why [/I]does having a continuous reflector have such a favorable impact on active elements whose optimal wavelengths are 1 to 2 octaves above VHF? Does the particular horizontal collinear arrangement of the active elements have anything to do with it? Does the horizontal spacing between the left and right active elements have anything to do with? Sorry, its just that my gut tells me the answer may not such a simple one..... Dunno...[/QUOTE]
