Horizontal Attic Loop Feed
"Dale Parfitt" wrote in message news:uQQii.2972$Np2.1287@trnddc07... "Wayne" wrote in message news:4EBii.3183$fw2.1666@trnddc04... Looks like I'll have to use a horizontal loop in the attic for a few months. Any opinions on how to best feed it? --open wire --coax coil balun --ferrite bead balun --straight coax The loop is about 13 feet per side, and I want to operate 20 meters and up. In the past I have simply used a coax feed without a balun. It worked OK, but there was a lot of stray RF around the house. TIA If the antenna is in the attic you are going to have RF in the house because the antenna is IN the house. Dale W4OP I wouldn't expect otherwise. It was just a comment about what was previously observed. In fact, the RF got into the computerized thermostat and burned out the computer. The new thermostat has ferrite chokes on the leads, and it has survived nicely. |
