Bias-Tee Power Delivery
Powering a preamplifier on your tower is pretty straightforward, right? Just run a power line up the tower and plug it in! Well, that's more cable to run up the tower and more cable to maintain. You've already got perfectly good coax going up the tower; why not just use that? Well that's exactly what we're going to do! Using a bias-tee (or bias-T) SFRC President Jeffrey KI6SGV will tap off a DC current sent over the antenna coax to power a preamplifier in a satellite rig. Come see the design, build, advantages, limitations and flexibility (and great price!) of this kind of power delivery system. With a little luck we'll have a working unit for a demo!
