The cushcraft vertical sounds like it might be a cushcraft R-5, R-7 or R-8
antenna. These antennas had counter poise radials and did not use ground
radials. I had all of these antennas at different times and talked all
over the world with them. I don't believe cushcraft makes them any longer.

Subject: Observations about a cushcraft vertical antenna
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 good luck
with it for the past few years, even though I have it in my attic. I
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'.
