- Television lead-in wire connects the receiving set to the antenna. Good quality 300-ohm wire is used for both VHF and UHF receivers.
- A TV set coupler is a loss-producing device for connecting two or more TV receivers to the same antenna. The loss introduced into the circuit is small, but can be critical in “fringe area” reception. In such areas, you should be aware of this small loss and to expect a slight reduction in signal strength at the receiver.
- A lightning arrestor mounts on the outside of the house as close to the TV receiver as possible to protect the receiver against lightning damage. The lead-in wire is attached to proper contacts and the ground rod to ground connector. Lightning will jump the gap inside the arrestor and flow into the earth if the circuit is properly installed.
