Default 60 meter vertical (was: WEDNESDAY: More Of Our Soldier Die for Bush's Lies)

But back to the subject, has anyone used a 160 vertical, or 160 inverted
L, on 60 meters (5 MHz)? 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)???

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.

A 5/8 wl has gain over a quarter-wave, of course, but so does a dipole
I think they are roughly the same (that is, 5/8 vs. dipole), and the
reason I'm asking is because of the ERP requirements of the 60 meter
allocation.

All the best, and 73,
Dave

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).
