Daniel te da una opci¨®n que estar¨ªa bien.
Tambi¨¦n podr¨ªas hacer un Dipolo triple en el ¨¢tico si ¨¦ste es suficientemente grande.
Pero ser¨ªa un Dipolo en forma de herradura.
Por otra parte, existe la opci¨®n de una vertical de 7 metros de largo, con un "sombrero capacitivo" en la punta? de unos 30 ctms de di¨¢metro. Esto baja la est¨¢tica cercana y te da proyecci¨®n a m¨¢s larga distancia en recepci¨®n.
Estoy tambi¨¦n aqu¨ª si necesitas algo.

That sounds like a very limiting scenario indeed.?
Any chance you could put a dipole on the outside above your roof,
even if fairly low to the roof?? It would be further above ground
than recommended, but the chances are that you be getting some
reflections off the house somewhat similar to what you'd be
getting off the ground.
Which direction is your backyard from the house?? If it points
roughly south, a sloped dipole going from the roof of your house
to however high you can get it at the far end will be as good as a
dipole running east-west.? I like to model antennas with computer
software and can prove that with antenna plots if you want.
There is a pretty pricey alternative.? If you know of somebody
with room to spare, you could try a remote receiver using the new
networked receiver from SDRPlay.? It would set you back about $500
though.

Hello everyone:
I've been using some low-quality antennas to try to detect
Jupiter but I have not had success, so looking for other
ideas.?
My fundamental problem is I have no way to set up anything
remotely like the Radio Jove dipole I should be using. I
realize that's the "right answer", but I do not have anywhere
where I could physically place one.?
My problem is this. I live in a house, but I have a somewhat
annoying set of constraints:
1) My "back yard" is entirely concrete- no grass to ground
anything into
2) There are also some large power lines just outside the
backyard?
3) There are no trees I can tie anything to
Most everything I've read suggests I should make a dipole and
either ground it or tie it to a tree, and be far away from
power lines, so you see my dilemma. It may just not be
possible. The best idea I've come up with is to put a portable
dipole or EFHW in the attic, but I have not seen any reports
of detecting the decametric emissions with such a setup.
Has anyone had success with a more compact setup or one that
doesn't depends on grounds or a tree under conditions such as
these?
