Co-phased collinear for 2m – discussion of phasing devices

An exploration of a cophased collinear array with coax phasing stubs explored various structures for encouraging co-phase operation of a 3/4λ vertical over perfectly conducting earth (PCE). This article expands that set with NEC-4.2 models of some variations on the traditional Franklin form of the antenna. Let’s start with review of the traditional Franklin form … Continue reading Co-phased collinear for 2m – discussion of phasing devices
