[QUOTE="ProjectSHO89, post: 123031, member: 4698"]More likely, it's a fat-fingered typo since the verbiage in the Overview section says "[B][U]doubles[/U][/B] [emphasis added...] the power of traditional bow tie designs. ...". What that means, is you don't have ANY evidence at all of such. Actually, you've exaggerated that one. Back in the 80s, the ARRL set as editorial policy that all advertisements in their publications for antenna gain be derived from computer modelling rather than "range" or similar testing since the testing could be cooked to enhance results. OTOH, anyone with the antenna's physical measurements could run the same simulation and should produce almost identical results. That means that you could get an antenna for measurements and run the simulations yourself with one of the publicly available simulators like 4NEC2 and you'll then be able to comment knowledgeably about the antenna's performance. Nonsense. Simulations are performed in "free space". OTOH, "testing" could be done on that same real patio and the antenna performance may well be affected by that location and its surroundings.[/QUOTE]
