Default 80M antenna question

My country total on 80 CW is very small, so I plan to do something about it.
I'd like some recommendations on a modestly priced 80 meter DX antenna. I can
build it or buy it.

I plan to put up the antenna atop a five acre piece of land, at about 1200 feet
above sea level. There will be no power lines nearby.

Is a vertical a good solution, or would a dipole be better? What about
practical heights for the wire antennas, and should the vertical be elevated or
placed on the ground?

Thanks in advance,
Gary K5QT

Have you considered the Titanex 160/80/40 m Vertical? With a sufficient number
of radials that should do a good job and give you the one or the other
occasional new one on 160, too.

What is your current antenna?

I'm currently using a "mini-G5RV" with a height of 25 feet, in a
deed-restricted subdivision. I'm moving to the country in a couple of months.

Hi,
For what I experimented during this low solar activities where we all need
an excellent antenna to work in low bands, the vertical like a R7 placed on
top of a 10m high mast, with a dozen soft radials burried into the ground is
perfect.
I did another test with aluminum tubes, 20m long "only". Was light enough to
be erected alone then a 2d man to pull on wires and erect it perfectly.
Signal QRO, similar to R7.

A dipole, but very long, 30 or 60m long, or even a beverage if you have some
place left can also worked and will display some lobes? Try to place it as
high as you can (lambda being quasi impossible).

See also ARRL ant.hdbk for curtains like antennas and other variantes and
the famous ON4UN book about working low bands.

Hi Gary,

we are using a GAP Voyager DX IV (have a look at there WEB-Page)
with great success. It has only 3 radials and is good on 40+80,
Not too good on 160. I worked Heard Isl. a couple of years ago during
a huge European pileuo without a problem Same with HC8.
In my opinion a fine antenna. The only disadvantage is a vy noisy RX,
but this is also a QTH question. We are in an idustrial area....

Gud luck on 80m.
