Robert 11,
"IF" you have a Long Wire Antenna that is located OutSide then you should look at those things that can be done OutSide to improve your Antenna System from the effects of a nearby Lightning Strike to your Antenna, Radio Equipment and possibly your House. 1. An OutSide Remotely Located Ground far away form the House. 2. With a LongWire Antenna use a Matching Transformer (UnUn) between the Wire Antenna Element and Ground; and the Coax Cable Feed-in-Line. 3. Use a Coax Cable Feed-in-Line and bury it if possible. 4. Use an Antenna Switch between the Antenna's and the Radios in the Shack. The type that lets you dixconnect the Antenna from the Radios and Short the Antenna to Ground for Safety. Note - Many of these Antenna Switches have GDT's built into them. http://www.universal-radio.com/catalog/switch/2415.html 5. When you are not using your Radio and Antenna disconnect the Coax Cable from the Matching Transformer outside the House. "IF" you have a Long Wire Antenna that is located InSide your House or Attic. 1.A Ensure that your House and Wiring meets the Standards for your Area for Lightning Protection. 1.B. Improve your Shack Grounding and Electrical Sysyem Bonding as best as you can. 2.
