Well not really. There is a "Giant Difference" between Land Based HF and MF Rf Ground systems and those that can be constructed aboard ANY Vessel. Yes Radials in a Land Based Antenna System aren't designed to "properly couple it's image to the soil." They are to provide that image for the antenna system. The soil has very little to do with the Rf Gound System in a conventional Marconi Antenna System. If it were otherwise one would expect to see a lot more "Soil Remediation" going on around such Antenna sites, like adding Salt to the area, or Chicken wire, bonded to the radial system. On the contrary. They (buried radials) provide coupling. The soil itself provides the image. That's why there is, in fact, a lot of "Soil Remediation" - like adding salts and chicken wire and grin even radials. Waves also really don't have a lot to do with Antenna system in the Marine Enviorment. Unless they put the bottom xx feet of the antenna under water (c: "Conventional wisdom puts the antenna as high as possible." Nope, not really. The antenna just needs to have sufficent length,.... Trouble is few boat owners or installation techs understand what you are saying. They believe higher is better as a matter of faith. Thus ..... |
