I want to buy a new antenne, i think it's gonna be the ala-1530 or the
rf sysytems dx1promk2.
Anybody here as experience with these one's? witch performce better?

The ALA 1530 is also a great antenna, but to match the performance of the
DX-1 it would have to be mounted on a rotator.
If you did that, it might also be better at suppressing urban RFI.

The 1530 is a great antenna. Here's a review of the ala 330, which is
basically the same antenna, with more gain through the shortwave bands:

Ok, thanks for the reply, i shall visit the mentioned site and do some
reading.

I understand that the 1530 must be used with a rotor,to get the best
results, correct me if i'm wrong.
I have not much room over here, so i'm curious how it performs under the
roof?

hi Henk...

I use the 330, and once i'm free of this chemo, i'll be ordering the
1530.
i got the 330s because i'm more into SW than MW/LW. i'm on top of a
mountain
in w.pa. 6 acres, lots of room for all kinds of ant. you can mount the
loop a
number of ways. read the reports from a number of web sites and you will
see
what i mean. on SW you can turn the loop for qrm or to cut out a boomer
to find
that low power station you have not heard before. check the loop groups
on yahoo
for some great info. and, RHF, will be along with some good info for you
also.
i love to play with all kinds of loops. i have 7 different types. great
fun. and,
Joe A. will be along with some great info for you. he has his 330s in
his attic
on a rotor. my 330s hung in my dining room, for about 6 months last
winter, from
a bungee cord to a large ceiling fan. worked great, and i could rotate
it by
turning the fan. right now it's off my rear deck, on a 10 ft. mask, i
can turn
by hand. these loops are first rate. you can email wellbrook with any
questions
you may have. after i get the second loop, both will be mounted in my
attic like
Joe's. like i said, these loops are first rate...Good DX...

That sounds good, i actually in the middle of a city(all buildings
around me) so for wires is almost no room, i shall visit the yahoo group
about the loops, my main listening is utility and sometimes aero.
Thanks for the information, i shall keep it in mind.

Henk.

I did a www.devilfinder.com search for,Build your own radio
antenna rotators.You might want to check that out.

It has more to do with the incoming signal to the antenna. The lower
frequencies look more like a signal point source so then the antenna
pattern has an appreciable effect on the received signal strength.
Certainly you will see the loop null on a AMBCB daytime signal and
chances are you will also at night depending on where the signal is
coming from because at that time you could have either or both sky wave
and ground wave.

The smaller the loop size relative to the received wavelength the
better defined the directional pattern.

For SW the higher the frequency the more the signal energy is scattered
by the ionosphere so again the antenna pattern is effectively less
defined. Some people report small loop directional characteristics are
evident up to around 5 MHz. I have had a small loop of 20 foot
circumference showing a null at 5 MHz myself. I expect that a smaller 1
meter loop might show a null up to 10 MHz but a null in the pattern is
a lot less likely higher in frequency than that.

Well, I keep talking about nulls because the loop pattern response is
very broad and you are only likely to notice the null in the pattern.

My experience would seem to bear you out, Telemon. I have a 330S and
originally had it on a rotor. However, because the antenna's
directional characteristics disappear at around 4 mhz or so, and I
don't do a lot of listening 'down there', I opted for a simpler setup
without a rotor. It'd be different if I had a 1530 though. I think I'd
insist on a rotor then, since the 1530 operates best on the lower
frequencies.
