Hi there, I have some radio equipment, I live on a hill with big oak trees, and I have a lot of wire. I'd like to set up a strong antenna for receiving, that I can potentially improve later, for transmitting. But I want to get the receving set up immediately. Here's what I have: A Realistic TRC-430 CB radio, with car antenna; A JVC RC-M70JW boom box with shortwave receiver; An RTL-SDR.com Software-defined radio dongle. I also have a lot of outdoor telephone wire. There were three lines coming into the house from a previous owner, and I took the wires off the house and the telephone pole that's on my property. Each line is easily over 200 feet. So here are my questions: The first antenna I want to set up is for shortwave receiving. The phone lines are two wires together, like a speaker cable. Every tutorial I've seen for longwire antennas shows only a single wire. Does this mean I should split my wire down the middle, and only run one strand? Or should I tie the ends together? I plan to cut the longwire to 203 feet, because that is a recommended length for random wire. Then I would run a second length of phone line from the back of the boom box, which has two screws for antenna terminals, and attach both wires to the one longwire. Is that right, or can I just get my longwire the length I want, then bend it over an insulator and run it all the way into the house, to the boom box? I guess I'm not clear why there are two terminals if the end-run longwire is a single strand. I have to ground the antenna, or the boom box. The box has a phono input, with a ground terminal. Can I just run a wire from the ground terminal to the ground of an electrical outlet? Or, should I run a separate wire from my longwire antenna to an outdoor ground? I could run a wire to my home's grounding rod—is this better than grounding the boom box? Can I use my longwire for multiple receivers, if I'm not using them at the same time? For instance, if I run another receiver to the same longwire, but the first receiver is connected but turned off, can I use the wire with the second? Is there a good way to get my CB car antenna working at home? Right now, if I stick the car antenna to a metal porch swing outside, I get nothing at all. Should I put the antenna on the roof? I assume I would need to run a metal pole to the ground, separate from the one that received the service drop wires, since everything I read says to keep antennas away from power lines. If I run multiple, random-length longwires at significantly different lengths, and connect them all at the one line running to my boom box, will I improve my coverage? I see a lot of tutorials on youtube where people space out their longwires and run them together, but I assume I could have them going in any which direction. I know those are a lot of questions. I know very little about antennas, nothing about baluns, and I'm just starting out. But before I start cutting phone line and getting up on the 30 ft ladder, I want to make sure my first steps are productive ones that will pay off. Thanks so much for reading, and for your help.
