Default 75 meter hamstick vs low dipole

It just occurred to me that I have over looked something that might have
some use in this discussion. I just realized that this thread is about a
low dipole compared to a vertical Hamstick antenna. I reported that I have
compared a Hamstick dipole to a full size dipole and that it was down 20db
from the full size dipole. I can also report on a Hamstick vertical
compared to a full size dipole on 80m. For some years I’ve been using a
phased vertical system as a receive antenna on the 80m SSB Dx window. It is
2 Hamstick’s spaced 1/16 wave apart and feed 90 degrees out of phase with a
relay system that lets me switch directions. As a receive antenna it works
very well. A friend that has a 900’plus beverage tells me that it compares
very well. For me it gives me about at 15db signal to noise advantage over
my transmit dipole. The front to back is also about 20db in the most
favorite direction. But here is the part that is germane to this thread.
The signal level compared to the dipole is still about 20db down. I don’t
care as receivers have a lot of extra gain and the increase in signal to
noise makes all the difference. I don’t have much of a ground system, just
4 10’ radials under each vertical but putting down a good ground will not
make up 20db, no way. The main advantage that a beverage has over this
antenna is that it will cover several ham bands and the Hamstick verticals
are only good for about 100Khz around the DX window but that is all I want
and it fits in my yard as the spacing is only about 30’.
So I can say that a phased hamstick vertical on 80m with a poor ground is
also about 20db down from a full size dipole at 40’.
