Me again. I just got "handed" a potential project. I am looking for information on the phasing harness for Sinclair VHF 4-bay dipole arrays with the coax inside the mast. I want to know types of coax and lengths so I can understand the matching. I could use info on both the bidirectional and cardioid versions, but especially cardioid. The harness lengths must be different in order to cram it inside that mast. Burt? Or anyone can shed some light on this? (I was thinking Burt had some info on a web site somewhere, but I can't seem to find it)
I am aware of the 125 ohm quarter wave section inside Sinclair dipoles, but want to know about the rest of the harness. I am wanting to attempt the difficult or, maybe, impossible... I am trying to figure out if it would be possible to use dipoles from an SRL235-2 to rebuild what is believed to be and SRL214, and at the same time convert the antenna from bidirectional to cardioid pattern. I would be constructing my own harness. I think this might be possible, if I can find out how the phasing harness for the SRL214/cardioid version was made. Any info out there? Paul N1BUG
