- Understanding Impacts of 75-ohm Devices in 50-ohm Systems
- This article explores the implications of using 75-ohm devices, common in TV setups, within 50-ohm systems. While mismatched cables and connectors may lead to minimal consequences in receive-only setups, potential losses and reduced isolation in splitters and taps are examined. The article concludes that, for general applications, inexpensive TV-type components can offer reasonable performance with some trade-offs
