[QUOTE="Piggie, post: 45420, member: 2941"]Which elements? My 4221A measures 7.5 inches per element. If you take the virtual distance from tip to tip of 16 inches, that is close to a 1/4 wave at highband. But you are comparing that to a 1/4 length of metal that is feed at it's end as a Marconi 1/4 Wave. On the N-Bays the quarter wave you describe would be center feed. I have no antenna to compare that with except to call it an 1/8 wave dipole, that would have a huge mismatch. Also even to presume the virtual distance from end to end of a diaganol pair in a N-Bay is continuous would not be any more true than because an DB8 has as wide of reflector it too should resonant at VHF as does the reflector of an old CM4228A.. Now. As always I could be wrong, but this idea just hit my sense of antenna sideways and why I pose an opposing view.[/QUOTE]
