Ok I have not ever used wire antennas but I suddenly got the urge and Im stumped regarding hooking up this New SG-235 remote tuner that just arrived. Does anyone have experience with these? First I have a flagpole antenna with a ladder feed, power to the top long section and the ground to the first bottom section. Questions: 1. This SG-235 tuner has one post only at the top for the positive wire, do I connect the other side of the ladder to the grounding lug on the tuner? 2. The coax feed of this tuner is strange, the shield and the center feed have continuity between them, My ohm meter shows that, is this a short? 3: Why no continuity from the coax shield to the ground lug of the tuner? NOTE: My hard line run is grounded so is this an issue? 4. I have a power supply to power up the tuner,,Red (power) and I see a black and purple wire soldered together assuming this is the ground, correct? 5. Why does the (Ground) soldered black/purple wire have continuity to the Hot Post on top of the tuner? Please help, this was a very expensive tuner which Im sure Im doing something wrong. |

http://www.sgcworld.com/Publications/Manuals/235man.pdf The manual includes a schematic. It appears that T1, T2, and T3 provide a DC path to ground from the RF Input. It may help to study the schematic and the hardware to better understand how it works. Zak Lau W1VT ARRL Senior Lab Engineer |
