From what limited info I can see on the web, it's a 5/8 wavelength and is very close to a dipole in the ERP result. 73, Dave Shouldn't a 5/8 be a gain antenna (around 3.5 dB)??? |

Excellent deduction, you stupid ****. WOW!!! |

I have a 90 foot vertical for 160 meters.
Yes, I have tried it on 60 meters. It seems to be about equal to an inverted vee at 60 feet at long distances. For short skip, as expected, the inverted vee wins. It is over a VERY extensive ground screen. A 90 foot vertical is the same as a 90 foot dipole, except it is in a different orientation and is fed at the end instead of in the middle. Since the FCC rules do not address these distinctions, AFAIK this is a regulation dipole into which you can transmit 50 watts. Rick N6RK "Dave KZ1O" wrote in message .. .

A 5/8 wl has gain over a quarter-wave, of course, but so does a dipole ![]() reason I'm asking is because of the ERP requirements of the 60 meter allocation. All the best, and 73, Dave |

Rick N6RK The FCC does require that you be able to show your calculations or measurements to confirm that it is equivalent to a dipole (i.e. no gain). Dee D. Flint, N8UZE |
