Hello,
Please, has anyone out there any experience of using a Cushcraft R7000
vertical ant?
I was thinking of buying one second-hand.


Hi,

Excellent vertical. Over 295 DXCC confirmed in several years.
Less good during low solar cycle as now, but still good, much better than
any G5RV (I use now). A bit sensitive to QRM.
Works fine at ground level with soft radials burried into the ground but
best results are obtained at about10m high (on a small pylon) and with 10
radials in the ground.

Another ham used it too : see his QSL album on http://www.qsl.net/on4ldu/

Hello again,
Thanks to Thierry and Surious Noise for the info.Certainly ON4ldu seems to
think a lot of the r7000 but opinion on the 'eham' site seems divided.
Perhaps the 7000 is OK if you have a little time on your hands and a little
patience?

I'll think about it.

Thanks to all, you've been a great help.

When you ask the question "How good is an xxxxx antenna", you have to
remember that the answers are all relative - to the type of antennas
that the person answering the question has used.

A guy who's never had a directional antenna, and who was using a G5RV
up 10 feet will tell you that a mutiband vertical is WONDERFUL.....

A guys who's been using a five element monobander on every band will
tell you that a multiband vertical sucks.........

So one guy will be very happy with it, and another will not.

What YOU have been using may be the deciding factor in the question
will YOU like it.....

I would venture to guess that if you put up a dipole on any particular
band, and compared it in real time to the R7000, you'd find the dipole
usually worked better. But then you'll need a bunch of dipoles to
duplicate each band, and maybe you don't have that much space.....

I don't know much about antennas, technically, but I've always like to

play with them, and I have the habit of comparing antennas with each
other - always try and have two I can switch - instead of comparing
what other people think about them. With lots of sunspots, you can
work 278 countries with a chain link fence for an antenna, so boxes
full of QSL cards don't necessarily indicate that an antenna works
well.

Having used a few of different multiband verticals in the past, I'd
say your money would be better spent on a ball of wire (if you have
the space to put it up). With two trees, some rope, and some wire,
you can build a four element 20 meter quad for a couple bucks, and
it'll beat the vertical by 40db.....

You might want to look at the Butternut HF2V, it's 40 & 80, no
traps.

Hi Jim,
Well yes, of course your basically right, though I might quarrel with your
40db for the quad and in any case I'm a little low on tall trees!

Really all I want to do is get the current node a little higher into the
air and the 7000 looked as if it may be the answer (compared with my
1/4-wave at ground level). I don't want to alienate the neighbours so the
less stuff I put up, the better.

Right now I'm torn both ways ----- from all accounts the 7000 may need a
little maintenance as time goes by, especially as where I live the wind
howls and howls during the winter.

We'll see! I only work 40 c.w. ("so why a multiband ant ?", I can hear
everyone howling). I may well end up with a dipole with the middle tied as
near the top of my GP as possible. I have a good takeoff over the sea so
that should be worth a db or two.

Best wishes,
Frank
