Just some preliminary unscientific observations. I have been
using a Cushcraft vertical on 20 through 10 meters for a couple
of months now. Sorry, I don't remember the model number. It is
mounted on a ten foot steel post behind our garage and has its
own ground rod, but only small radials on the antenna itself.
The bottom of the antenna is just a couple feet above the garage
roof. The antenna has a match box at the feed point where the
coax connects at the bottom. Sorry I can't remember the model, a
ham friend gave me this used antenna. Anyway, my point is that
it's my first use of a vertical on HF and is not as noisy as I
expected it would be. I also have a DXCC dipole that works on
the same bands and I can switch from one to the other antenna for
noise and signal comparison. I can't really tell much difference
between the two antennas so far. 73, Jim WA6EKS

I have the 5BTV ground mounted and honestly I don't really see it
being as
noisy as I expected hearing my whole time as a ham how noisy
verticals are.
Height might make a difference but with being in a trailer park
and all
buildings being the same height, I'd have to guide it like crazy
if I went
above the roof. I did think about it. I have it guided now with
very light
rope tied to the house and shed but still half of it is above the
roof line
of all buildings in this area for miles so when we get wind, it
sure gets
the worst of it. I did it to be safe.

I used the 4BTV with four radials on each band on my rooftop and
it
worked extremely well. It was noisy like all verticals, but DX
was
readily available.

I have the Alpha Delta DX-EE, and it's a good dipole. I've had

haven't used one that's exposed to the elements though, so I
can't tell
you
how it holds up under adverse weather.

Is there anyone here on our list personally familiar with either
of these
antennas, and if so, what feedback can you give me about them?
1. The Alpha Delta DX-EE
Description: Alpha Delta "ISO-RES" inductors replace lossy traps
and
capacitors, rated for Full Power; Direct 50 ohm feed, no antenna
tuner is
required except for extended frequency coverage; Fully assembled
with
insulated #12 copper wire, stainless hardware and 50 ft. of
nylon rope;
Includes the DELTA-C static protected center insulator and
DELTA-CIN end
insulators; Installs horizontally OR as an inverted V; covers:
40-20-15-10M
plus 30-17-12M using a Wide Range Tuner, 40' Multi-band Antenna.
2. Hustler 4BTV -- 4 Band Trap Vertical
Description: 4 Band Vertical HF Fixed Station covering 10, 15,
20, and 40
Meters; 21'.
