Hello Alain,
Welcome to the hobby. Lots of ways to have fun. Whether you like a
particular antenna or not, depends on what pursuits you take up in your quest
for fun and satisfaction in the hobby. Your G5RV can play just fine forever,
depending on whether you are looking for local or regional stateside contacts,
or looking for long range, DX contacts. The two pursuits favor quite different
antennas.
This reflector is a very good one, for answers to questions like yours
of how or whether to mount masts or towers or other antenna supports to
buildings.
(or any other antenna structure planning question.)
80 mph is serious wind, and to mount a 30 ft mast
(actually, I hope you mean tower, such as Rohn 25, as opposed to a
mast) in 80 mph is non trivial, and certainly far beyond a couple of
u-bolts through the eaves; even a purpose built wall bracket needs
substantial structural backing (engineering) before screwing it to a
side wall of a house. So, to help you, many wizards, are accessible
here on Tower talk. You just have to narrow down your goals, as you
begin your adventure in ham radio, to ask the right questions.
If budgets, or space limit your options, and you are after DX, height is what
you want to invest in, if you have horizontal antennas. Try to get more than
1/2 wavelength, preferably 1 wavelength, which for 20 meters is around 60 ft.
If you had and compared two rotatable dipoles, one at 30ft, and one at 60 ft,
and you were listening for European Stations from California around sunset, or
in the morning, there would be a (probably) a profound difference in what you
hear. Once up at 50-60 ft or so, even simple wire antennas work DX very well.
In your case, being discreet, points possibly to a near-ground mounted
vertical, which finds the long range contacts much more easily, and through a
totally different mechanism than horizontal antennas.
Welcome, and enjoy....
All the Best, 73,
