Antennas - Is NVIS a good thing?

It certainly does that. It can be a test of how quickly a group can gets stations up and running. It can be a test of which groups are better organized and it can certainly be (and is) a test of how efficient operators can be in copying a message quickly and accurately. They keep and publish scores, do they not? That's a contest as well as an exercise. And a time to experiment with new techniques and technology in an "emergency" setting without it being a "real" emergency. I'm going to be bold in stating that I believe Field Day is a terrible time to be fiddling with new techniques/technology. It is a simple matter to do that well in advance of Field Day. You certainly wouldn't want to experiment with new techniques/technology in an actual emergency. Considering the relative ease of setting up an NVIS antenna system, and the number of other stations on the air, Field Day makes a perfect time to see how it performs and to map it's effectiveness for short range HF communications. I could have done that last Tuesday. The bands are loaded with stations almost all of the time. The results of installing an NVIS antenna are well known. They work better for working stations within a few hundred miles of your location. Install a low dipole or install a dipole at medium height above ground with a reflector under it and voila! Maybe I'm going blind in my old age, but I just don't see contesting under 47CFR97.1 You're right. Neither will you see anything about discussing non-functional body parts on 75m, participating in a large roundtable discussion or DXing. There are numerous things not addressed. That does not mean that they are prohibited. Dave K8MN |
