Webputting it higher, in other words—this will greatly reduce the likelihood of interference, which decreases at the inverse square of the distance. For example, doubling the distance reduces the potential for interference by 75%. As a further benefit, a large antenna doesn’t look anywhere near as large at 120 feet as it does close-up at 35 feet. WebTable 1 – Dipole performance over average ground. The flat-top dipole calculations in table 1 surprised me. While, no doubt, extending the height range beyond 100 feet would have …
