"Here I go again" (quote from Ronald Reagan, don't want to be a Mike Barnacle) ... If I properly stack two matched tri-banders and if the match perfect, I understand that I have twice the capture are
You're rignt - Here we go again! Let me try this one: This isn't exactly how I'd describe it. In general: The gain of a stack in the first (lowest angle) lobe ranges from 1 to 3 dB more than either t
Clarification: If the stacked antennas (both fed) are pointing within a 3 dB beamwidth but not within the 1 dB beamwidth (or so) there will be a problem. In other words, use the stack as a stack (poi
Hi David, "Capture area" is mostly an amateur radio myth used to create an advantage where none exists!!! I think it was derived from the useful term "effective aperture" which is a function of direc
Where is a source of incoming angle by freq, etc? Has anyone ever *Measured* incoming angles carefully? 73, Guy. -- Guy L. Olinger K2AV k2av@qsl.net Apex, NC, USA -- FAQ on WWW: http://www.contesting
There are plenty of propagation programs available today. Just like antenna modelling, the various propagation models are very accurate and can let you know what to expect under various conditions. B

There was a thread about this on the 160 reflector. I think people incorrectly assume interferometer or other nulling/ peaking techniques will supply the true optimum wave angle, but that isn't the c
Guy asks: Dean Straw, N6BV, has done extensive analysis of incoming angles using IONCAP computer simulations for several locations in the US and other parts of the world. K4OJ suggests reading "All t
