Two, thanks for the info on the SGC personnel.... that might explain why some of their responses to my emails didn't seem to make sense... especially their comments about NOT needing any balun. Three, and more direct to my initial questions, it appears we will be using coax between the coupler output and the antenna feedpoint.... up to 20 feet of low loss... we'll just eat the loss. But more importantly, I had intended, and will proceed along the lines of your comments on baluns, by installing a 1:1 balun at the input to the tuner. This will, at least, keep the RF out of the building and our station location. thanks. Ed Ed, you would be Much Better Off, if they would allow you to use (2) runs of Coax, side by side up the mast, and connect only the Center Conductor of each, to the tuner, with the shield left open on each end and sealed against water intrusion. Even if taped to the aluminum mast. This would provide a much better situation than a single coax feed. Also if you are stuck with a single coax, then make SURE, that the shield side of the coax is connected to the Ground Stud of the tuner. -- Bruce in alaska add path after fast to reply |
